MASTER OT J221526.55-102834.6 - PSN in dwarf irregular galaxy
MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 22h 15m 26.55s -10d 28m 34.6s on 2014-08-29.54444 UT. The OT unfiltered magnitude is 16.9m (limit 17.8m). The OT is seen in 8 images. There is no minor planet at this place. We have reference image by MASTER-Kislovodsk without OT on 2014-07-04.920 UT with unfiltered magnitude limit 17.9m.
The new object is located 7" east and 6" north of the center of dwarf irregular galaxy LEDA 68414 = WHI B2212-10. This area of sky in Aquarius is not covered by SDSS. Color-combined DSS finder chart is uploaded to http://master.sai.msu.ru/static/OT/J2215-1028-JRIR.jpg (10'x10' FOV). Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/221526.55-102834.6.jpg
