MASTER OT J032950.10+081619.6 - PSN
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 03h 29m 50.10s +08d 16m 19.6s on 2014-08-24.98325 UT. The OT unfiltered magnitude is 19.4m (limit 20.1m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2011-01-26.75233 UT with unfiltered magnitude limit 21.9m.
The new object is located 9" east and 4" south of the center of anonymous galaxy USNO-B1.0 0982-0045541 (03 29 49.47 +08 16 24.0 B1=20.43 R1=18.62 B2=18.24 R2=17.79 I=17.31). The host galaxy is not present in NED, 2MASS and GALEX. Color-combined DSS finder chart is uploaded to http://master.sai.msu.ru/static/OT/J032950+081619-BRIR.jpg (10'x10' FOV). Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/032950.10081619.6.png
MASTER OT J030831.74+142530.3 - PSN in PGC 1457807
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 03h 08m 31.74s +14d 25m 30.3s on 2014-08-28.00450 UT. The OT unfiltered magnitude is 17.2m (limit 19.9m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2011-01-11.68212 UT with unfiltered magnitude limit 22.1m.
The new object is located 1" east and 7" south of the center of the galaxy PGC 1457807. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/030831.74142530.3.png
