Central Bureau for Astronomical Telegrams
CBAT "Transient Objects Confirmation Page"
Discovery of many kinds of transient astronomical phenomena (e.g., comets, novae, supernovae, etc.) are traditionally reported to the CBAT. The Bureau is responsible for assigning designations to such astronomical objects as comets, supernovae, and Galactic novae.
This webpage, designed in 2010 for activation on 2011 January 1, replaces the former "Unconfirmed Objects Page" that the CBAT ran quite successfully during the previous decade, and which was updated manually by CBAT staff members. In contrast, this new webpage is designed to be updated automatically both by astronomers worldwide who are registered (via the CBAT) to do so and (when necessary) manually by CBAT staff. This addresses a strong desire in the astronomical community for immediate posting of interesting new transient objects, to solicit confirming observations (and thus to provide a place to post confirming observations, to help prevent potentially unnecessary observations at multiple observatories).
The TOCP is designed for use with stationary, extra-solar-system objects only. Data will be postable to the TOCP directly only by registered users, who can access RSS feeds and/or receive e-mails of new postings. There is no subscription charge for access (or posting) to the TOCP. Once items are posted on the TOCP, they will be available as RSS feeds -- as has been the case since 2009 for CBETs and IAUCs. The discovery reports posted on the TOCP will be sent automatically in standard XML format to the VOEvent system.
In order to post a discovery or follow-up observation to the TOCP, a user must be registered with the Central Bureau; instructions on registering and posting to this webpage are given here.

NOTE: TOCP discoveries that are published on CBETs/IAUCs or dismissed for other reasons are removed from this webpage and are listed on this separate webpage with cross-reference information..

| TCP J00003597+1757408 | 2024 07 11.0 | Andreoli.V and Castellani.F report the classification of TCP J00003597+1757408. We obtained, From Monte Baldo Observatory (OMB) located in Novezzina (Italy), a low resolution spectra (7x600s), by 0.25-m telescope + Alpy600 spectrograph (dispersion 4.9 Ang/pix), on 2024-07-11.007 . The spectrum shows a blue continuum and absorption in H delta (4100 Ang) and H gamma (4340 Ang) while H beta (4861 Ang) and H alpha (6562.8 Ang) are not present in our spectrum, probably filled-up by a disk. All the characteristics are typical of CV stars. We propose the classification of TCP J00003597+1757408 as a CV star. |

| PNV J00412371+4114594 | 2017 12 20.8507 | Emmanuel Conseil reports the discovery of a 15.5 magCV transient on 3x50s exposures taken with Slooh robotic telescope T2WF (17" F/6.8 + FLI PL16803) on 2017-12-20 at 20h25 UT. The transient is also visible on 3x50s exposures taken with Slooh robotic telescope T2UWF at the same moment(85mm F/7, focal reducer 0.8x, SBIG ST-10XME). This transient is located very close to the location of the dwarf nova M31N 1966-08a (also known as M31N 1968-10c) and could be a new outburst of this object. On 2017-12-20 at 21h29 UT, the transient has faded a lot on 3x50s new exposures, and is barely visible on 3 more images taken at 22h06 UT. Stacked (x3) images are available here for T2WF telescope : https://www.flickr.com/photos/econseil/38314239035 Stacked (x3) image is available here for T2UWF telescope : https://www.flickr.com/photos/econseil/39190450131 |
| PNV J00412371+4114594 | 2017 12 21.8750 | The transient has now disappeared (limiting magnitude ~19.5). Looking for litterature about its possible parent (M31N 1966-08a), I've found a very recent paper (https://arxiv.org/pdf/1712.05023.pdf), submitted last week, and showing that the outburst 50 years ago is probably not the consequence of a nova, but most likely a flaring star. That's the conclusion of Shafter et al. That might explain the rapid fading seen during the night of Dec 20th. |

| PNV J00422171+4112338 | 2011 09 14.643 | We performed optical low-dispersion spectroscopic observations of PN in M31 ( PNV J00422171+4112338 ) on 2011 September 14.643UT using the 1.3m Araki telescope(+LOSA/F2). The total exposure time is 3600 sec. The spectrum exhibits quite broad H-alpha and H-beta emission features. No other significant features could not be identified in our spectrum. The FWHM of the H-alpha emission line is about 4600 km/s. This suggests that the object would be a very fast nova and a candidate of recurrent novae in M31. M. Nagashima and A.

| TCP J01495677+5335018 | 2012 01 31.46 | We obtained a low dispersion spectrum (R about 550) of TCP J01495677+5335018 (=XMMSL1 J014956.7+533504; ATel #3896) on Jan. 31.46 UT with the Araki telescope with our spectrograph (LOSA/F2) at Koyama Astronomical Observatory, Kyoto Sangyo University, Japan. The Spectrum shows clearly a strong emisson of H-alpha, and absorptions of H-beta and H-ganmma on a blue continuum light. The absorption component of the H-beta was filled with its emission. The He I (667.8 nm) emission and a Na D absorption (E.W about 0.11 nm) were also detected. These features suggest that the current brightening of this object would be a outburst phnomenon in a dwarf nova. A. Arai, M. Nagashima, C. Naka (Kyoto Sangyo Univ.)

SN is located at about R.A. = 03h33m36.1s, Decl. = -36o07'34" (equinox J2000.0), which is 3" W and 52" N from the nucleus of NGC 1365.

| PSN J06161835-2122329 | 2013 03 01.66 | From images taken on 2013 March 01.66 with the Zadko 1 meter telescope (Gingin observatory, Australia) E. Conseil reports the discovery of a supernova candidate located at R.A. = 06h16m18.35s, Decl. = -21o22'32.9" (equinox 2000.0), which is offset of 51" W and 11" S from the nucleus of NGC 2207. The image was R filtered and the magnitude was R=14.4. The presence of the candidate is confirmed on images taken on 2013 Feb. 28.66 (R=14.6) and 2013 Feb. 26.66 (R=15.3) with the same telescope. The candidate is not detected on 2013 Feb. 06.72 (limiting magnitude R~19). Using NED parameters for the NGC 2207 galaxy, we fit the three Zadko measures on the template provided by the supernova 2012fr. If we assume a Ia type, this is compatible with a supernova which could reach the B max on 2013 March 10.0 (Rmax~13.7) and with an explosion occured at about 2013 Feb 21.0. Spectroscopic follow-up is important to identify the type of the supernova candidate. Images at http://cador.obs-hp.fr/sn_tarot/PSN_J06161835-2122329/ |

| PNV J06270375+3952504 | 2013 04 4.27 | A 3ks Swift observation of PNV J06270375+3952504 was performed on April 4.27 UT resulting in detection of a new X-ray source at the optical transient position. The Swift/XRT net count rate is 0.015+/-0.003 cts. The spectrum is consistent with kT = 3 keV thermal bremsstrahlung (integrated 0.2-10 keV flux of 4.5x10^-13 ergs/cm^2/s) with no absorption, however the number of collected photons is insufficient for a detailed spectral analysis. A bright ultraviolet counterpart of the flaring source is detected by Swift/UVOT having M2=10.55+/-0.05 (Vega system). Overall, the object might resemble a fainter version of GW Lib, another WZ Sge-type flare observed by Swift (Byckling et al. 2009, MNRAS, 399, 1576).

The OT unfiltered magnitude is 15.5m (limit 18.8m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2010-11-07.98868 UT with magnitude limit in 'BLANK' filter 19.7m. There is nothing at this position in USNO-B1.0, GSC 2.3.2, 2MASS, GALEX, 1RXS, GCVS catalogs and in AAVSO VSX. This area is not covered by SDSS and NEAT. Nothing is visible at the position of the OT on 9 available DSS plates and on their combination down to limiting magnitude ~21.5. Color-combined (BRIR) DSS finder chart is uploaded to http://master.sai.msu.ru/static/OT/J071856+601833-BRIR.jpg (10'x10' FOV). We have obtained follow-up images with MASTER-Tunka telescope simultaneously in two filters on 2012 Oct. 08.842 UT. The photometry is as follows: V=15.6, I=15.8. Based on the amplitude of variability (more than 6m) and color (V-I=-0.2) we suggest that MASTER OT J071856.78+601833.3 is likely a new cataclysmic variable (dwarf nova) in outburst.

| TCP J08371988-0602457 | 2018 10 21.8 | Kazuya Ayani, Bisei Astronomical Observatory, Ibara, Okayama, Japan, obtained a low-resolution spectrogram (range 400-800 nm; resolution 0.5 nm at H-alpha)of this TCP with the 1.01-m telescope of Bisei Astronomical Observatory on Oct. 21.8 UT. It shows absorption lines of H-beta, H-gamma, H-delta, He I (447.1 nm) on a blue continuum. H-alpha line is not discernible probably because the absorption is filled with the emission.

| PSN J09084248+4448132 | 2014 10 31.1351 | Several low resolution spectra of this transient were obtained on 2014 10 31.1351 by G. Masi abd P. Catalano, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 3, 300-seconds images were taken using a 100 lines/mm grating, with a dispersion of 34.5 angstroms/pixel. They were co-added and the resulting image shows Si II absorption around 6280 angstroms, suggesting this is a type Ia supernova. Assuming a recessional velocity of 8023 km/s for the host galaxy (UGC 09267, via NED), an expansion velocity of 10800 km/s is derived from the minimum of the Si II 6350-angstrom line. |

| PSN J14274900+1133400 | 2014 07 19.853 | Several low resolution spectra of this transient were obtained on 2014 07 19.853 by G. Masi, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 9, 300-seconds images were taken using a 100 lines/mm grating, with a dispersion of 34.5 angstroms/pixel. They were co-added and the resulting image shows Si II absorption around 6270 angstroms, suggesting this is a type Ia supernova. Assuming a recessional velocity of 7433 km/s for the host galaxy (UGC 09267, via NED), an expansion velocity of 11200 km/s is derived from the minimum of the Si II 6350-angstrom line. |

Other designations are e.g. USNO-A2.0 0675-23344754 (Bmag. 19.6, Rmag. 17.9), USNO-B1.0 0686-0567422, PSO J175459.999-212240.808 (gmag. 20.1, rmag. 18.7, imag 18.0); GLIMPSE G007.5785+02.0523, UGPS J175459.99-212240.7, and VVV J175500.00-212240.74 —— Patrick Schmeer (Saarbrücken-Bischmisheim, Germany) |
| PNV J17545999-2122401 | 2020 10 03.0981 | The latest ASAS-SN Sky Patrol observations (see also the link given by K.

Position end figures for Gaia DR2 are 55m00.10s in RA and 39.3" in DE (for the current epoch and equinox J2000.0). This red star is probably close to us (distance ~0.2 kpc), but the proper motion is rather small. Another red star, Gaia DR2 4070608344910091776 (Gmag. 19.99) is only 0.8" south of the reported position of the transient. The transient may be a reddened Galactic nova with an uncatalogued progenitor. Patrick Schmeer (Saarbrücken-Bischmisheim, Germany) |
| PNV J17545999-2122401 | 2020 10 03.0993186 | The transient is detected by ASAS-SN (Shappee et al. 2014, ApJ, 788, 48; Kochanek et al. 2017, PASP, 129, 104502) at g=12.23+/-0.02 2h 52m after the BraTS detection. Such a long duration seems unusual for a UV Ceti type flare and suggests that the object might instead be a Galactic transient affected by reddening (hence the difference between the unfiltered CCD and g-band magnitudes).

| TCP J18001854-3533149 | 2016 03 20.8 | Kazuya Ayani, Bisei Astronomical Observatory (BAO), Ibara, Okayama, Japan, reports that a low-resolution spectrogram (range 400-800 nm; resolution 0.5 nm at H-alpha) of this TCP was obtained with the BAO 1.01-m telescope. It shows H-beta, H-gamma, H-delta absorption lines on a blue continuum. Presence of H-alpha line is not clear probably because the absortion is filled with the emission. These imply that it may be a dwarf nova rather than a classical nova. The spectrum can be viewed via website URL http://www.bao.city.ibara.okayama.jp/astro/2016/tcp/TCP_J18001854-3533149_Mar20.png. |

The spectrum shows a blue continuum and absorption of Balmer lines except for H alpha (6562.8 Ang) which is not present in our spectrum, probably filled-up by the disk emissions, also D1 and D2 interstellar sodium are presents. All the characteristics are typical of CV stars. We propose to classify 2024rkw as CV. |

Klotz (Institut de Recherche en Astrophysique et Planetologie, France) on behalf of the TAROT Collaboration reports the discovery of an apparent supernova (mag about 15.6 +/- 0.2) on 2012 Aug. 19.122 using public images of the 0.25m robotic telescope TAROT La Silla observatory, Chile. SN is located at about R.A. = 21h01m58.99s, Decl. = -48o16'25.9" (equinox J2000.0), which is 7" W and 2" N from the nucleus of ESO 235- G 037. The supernova appear in an prediscovery image taken on 2012 Aug. 10.313 at mag 18.2 R. The supernova does not appear in an image taken on 2012 Aug. 07.133 (limiting magnitude 18.6 R). Spectroscopy was obtained by F. Colas (Institut de Mecanique Celeste et de Calcul des Ephemerides Paris, France) A. Peyrot and J.P. Teng (Association de Gestion de l'Observatoire Reunionnais d'Astronomie, Les Makes, Reunion island, France) using the 60 cm telescope at Les Makes, Reunion island, France (IAU station 181). A grating filter (300 tr/mm) gives a low dispersion (48A/pix). Date of observation is 2012 Aug. 21.6. We compared the spectrum of PSN J21015899-4816259 with spectra (provided by C. Buil http://www.astrosurf.com/buil/supernovae/2011/index.htm) of various SN types.

| TCP J21582885+2954056 | 2024 01 10.7777 | The CV=13.3 transient was discovered in nine 20sec exposure images obtained between 2024-01-10.6572 and 2024-01-10.7777 UTC using a 135mm f/2.0 telephoto lens attached to an unfiltered SBIG STL-11000 CCD. This is the secondary NMW survey camera ( http://scan.sai.msu.ru/nmw/ ) operating at the Astroverty astrofarm in Nizhnii Arkhyz, Karachay-Cherkessia, Russia. The previous image of this field, captured on 2024-01-07.6840 using the same camera, shows no transient brighter than CV~14.5 at the specified position. The CV unfiltered magnitudes were calibrate using V magnitudes of an ensemble of Tycho-2 stars in the field. The plate-solved FITS images and finder charts may be found at http://scan.sai.msu.ru/~kirx/img/TCPJ21582885+2954056/ The transient may be associated with a star PS1 143883296197442755 (g=21.9, r=21.8, i=21.5) located 1.7" from the measured position (within the expected astrometric uncertainty of a few arcsec). Given the low total Galactic extinction in this direction, A(V)= 0.33 (Schlegel, Finkbeiner & Davis 1998, ApJ, 500, 525), and the possible association to a Pan-STARRS source indicating an outburst amplitude of approximately 8.5mag, we suggest that the transient could be a previously unknown WZ Sge-type dwarf nova. ---- Stanislav Korotkiy (Astroverty, Ka-Dar), Kirill Sokolovsky (UIUC, SAI MSU), Sergei Ostapenko |

| PSN J23164332+3359476 | 2015 07 28.001 | I'm Constantine Emmanouilidi reporting a possible SN in galaxy PGC70909. The exact location of the candidate is J2000 RA: 23 16 43.32 Dec: +33 59 47.6 Magnitude estimation is around 17mag. I confirmed from MPChecker that there were no asteroids or comets at the time. I also confirm that the object is not moving in the three consecutive images with exposure time of 15sec. I'm sending you the fits file showing the possible SN marked. Today the weather is clear in Thessaloniki Greece and I'll have a chance to make a second confirmation image. The observation was made by Stavros Koukioglou who is a member of the Greek Supernovae Survey Team (GSST) that is coordinated by me and the data comes from my autonomous robotic observatory called KASTRO. It houses two catadioptric telescopes with 305mm and 350mm diameter. The observation was made with the 305mm telescope and a CCD camera without filters. The exposure time of the image is 15sec and its a stack of three images. I've searched through the Bright Supernovae page and didn't find any previous discovery. I searched with PGC, UGC and MCG names. I also looked the coordinates and even then nothing came up. I'll keep you posted today with newer images when they will be possible. Kind regards Constantine Emmanouilidi |

It was faint (mag ~21) on 1989 July 12 blue plate, but in outburst on 1989 Aug. 28. It is present in GSC 2.3.2 with coordinates 23 19 17.068 +48 31 14.16 and Jmag=16.95. Color-combined (BRIR) DSS finder chart is uploaded to http://master.sai.msu.ru/static/OT/J231917+483114-BRIR.jpg (10'x10' FOV) with comparison of 1989-07-12 and 1989-08-28 blue images at http://master.sai.msu.ru/static/OT/J231917+483114-anim-DDS-B.gif (200"x200" crop). The star has an ultraviolet counterpart GALEX J231917.0+483115 (NUV=21.61+/-0.32). It is absent in USNO-B1.0, 2MASS, 1RXS and GCVS catalogs, as well as in AAVSO VSX. This area of sky is not covered by SDSS, CSS and NEAT. Based on the blue color, amplitude of variability and presense of a previous outburst we conclude that MASTER OT J231917.03+483114.2 is a new cataclysmic variable (dwarf nova).

| PSN J23274086+2335214 | 2014 08 18.02 | A. Klotz (IRAP/CNRS, France), reports the sprectral observation of PSN J23274086+2335214 using the 94 cm telescope located at Saint-Caprais (France). The spectrum is 10 min exposure using an Alpy 600 spectrometer obtained at 2014 Aug. 18.02. H-beta, [OIII]-5007 and H-alpha lines are seen in emission at a redshift z = 0.01148 +/- 0.0015 which is compatible with the redshift of NGC 7673 (z = 0.011368 according to NED). The feet of H-beta and H-Alpha lines are spreader than that of [OIII]. The broad Balmer component and the absence of blue absorption of the Balmer lines suggests a typical young SN II supernova.
