2014 05 29.73
We discovered this object on May 29.73 2014 UT in the Tsinghua University-NAOC Transient Survey (TNTS), and the magnitude of the object on unfiltered CCD was about 17.5 mag. This supernova was detected on our survey images taken on May 25 and May 27, with unfiltered magnitudes being as 19.1 mag and 18.3 mag, respectively.

2014 06 05.83210
This transient was observed on 2014 06 05.83210 by G. Masi, remotely using the 17"-f/6.8 corrected Dall-Kirkham robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 16.6 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 31.06; 59.1 (J2000.0, mean residuals of 0.2" on both axes).
2014 05 30
This supernova was found by CRTS on May 30th as CSS140530:155831+125159. The discovery has been public since that date from http://nesssi.cacr.caltech.edu/catalina/AllSN.html and was announced shortly thereafter to the general community via http://www.rochesterastronomy.org/supernova.html
2014 06 05.94229
Several low resolution spectra of this transient were obtained on 2014 06 05.94229 by G. Masi, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 14, 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 6380 angstroms, suggesting this is a type Ia supernova.
