PSN J03481978+7007545   2014 09 11.7251*  03 48 19.78 +70 07 54.5  15.4 U    5W   4S  U2855     I 0


2014 09 11.8100

I confirm the presence of this PSN (mag.+16.3) from several unfiltered images taken by 0.35m. Sch.-Cass. F/5.5 + SXVR H-9 CCD camera; 60sec. exposure; limit mag.+18.5; Giancarlo Cortini (Monte Maggiore Observatory-Predappio-ITALY).



2014 09 11.725

Discovered by K. Itagaki, Yamagata, Japan, on an unfiltered CCD frame taken on 2014 September 11.725 UT using 0.60-m f/5.7 reflector at Yamagata who has put the discovery image at http://www.k-itagaki.jp/images/u2855.jpg. Nothing is visible at this location on his past frames including the most recent frame taken on 2014 Sept. 7.680 UT and verifying was done on a frame (limiting mag.= 19.5) taken on 2011 October 27.872 UT using same telescope for both frames.



2014 9 11.9484

I took confirmation image of this PSN in Luminace and V filter with 0.32m f8.0 astrograph + SBIG STL-6303E CCD camera at Nerpio, Spain, remotely. Photometry result was V=15.86. My image is available at http://meineko.sakura.ne.jp/ccd/PSN_J03481978+7007545.jpg, Seiichirob Kiyota (Kamagaya, Japan)



2014 09 12.53459

Mag.= 15.4U, position end figures 19s.93, 54".3 on three stacked 60-s frames (limit mag.= 17.5), using a 0.30-m f/7.0 Cassegrain + SBIG ST-1001E camera at Osaki Lifelong Learning Center, Japan. Observer T. Yusa, Y. Suzuki, and K. Kato, Osaki, Japan. An image was posted at URL http://space.geocities.jp/yusastar77/supernova/PSNinU2855_140912.htm



2014 09 12.95155

This transient was observed on 2014 09 12.95155 by G. Masi, P. Catalano and P. Schmeer remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 180-seconds exposures, unfiltered, show the source at mag. 15.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 19.86; 54.1 (J2000.0, mean residuals of 0.2" on both axes).



2014 09 13.453

Mag.= 14.9, position end figures 19s.94, 54".0 observed by T. Noguchi, Chiba-ken, Japan, using 0.23-m f/6.3 Schmidt Cassegrain + unfiltered CCD. See an image at http://park8.wakwak.com/~ngc/images/PSNinUGC2855.jpg.
