MASTER OT J040352.13+332556.4 - Possible Supernova
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 04h 03m 52.13s +33d 25m 56.4s on 2013-11-24.85205 UT. The OT unfiltered magnitude is 18.2m (limit 19.2m). The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2012-09-21.04574 UT with unfiltered magnitude limit 19.7m. New object was confirmed on 2013-11-28.94759 UT at 18.4m (limit 19.3m).
The OT is located 10" west and 5" north of the galaxy 2MASX J04035291+3325518. We also note there is an X-ray source 1RXS J040355.0+332615 (flux 0.0446+/-0.0116 cnt/s, hardness ratios HR1=1.00+/-0.16, HR2=0.36+/-0.24, error radius 16") formally 40" away.
We suggest that MASTER OT J040352.13+332556.4 is likely a supernova. Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/040352.13332556.4.png
MASTER OT J132248.38+333020.7 - Possible Supernova
MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 13h 22m 48.38s +33d 30m 20.7s on 2013-11-28.88726 UT. The OT unfiltered magnitude is 16.5m (limit 18.0m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2012-08-19.53226 UT with unfiltered magnitude limit 18.2m.
The OT is located 7" east and 11" south of the galaxy PGC 2033541 = SDSS J132247.82+333031.9 (z=0.0387). We suggest that MASTER OT J132248.38+333020.7 is a supernova. Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/132248.38333020.7.png
