- Аннотация: MASTER OT J102725.40-172356.7 discovery - PSN in PGC883918 MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 10h 27m 25.40s -17d 23m 56.7s on 2017-10-24.1072 UT. The OT unfiltered magnitude is 17.4m (mlim=18.64). The OT is seen in 2 images. There is no minor planet at this place. We have reference image on 2015-03-15.0663 UT with unfiltered mlim= 19.0m. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/MASTEROTJ102725.40-172356.7.jpg MASTER OT J011700.59-105906.0 discovery - short OT MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 01h 17m 00.59s -10d 59m 06.0s on 2017-10-24.02622 UT. The OT unfiltered magnitude is 19.3m (mlim=20.5). The OT is seen in 3 images: 2017-10-24 00:37:45.844 m_OT=19.5 2017-10-24 00:41:24.297 m_OT=19.3 2017-10-24 00:45:03.272 m_OT=19.7 202017-10-24 01:55:20UT m_lim=20.3, no OT There is no minor planet at this place (the nearest (96825) 1999 RA185 is in 2.7W,2.8N - not our OT, see image) . We have reference image on 2017-09-25.03440 UT with unfiltered mlim= 20.8m. Deep photomtry is required.

The OT unfiltered magnitude is 19.5m (mlim=19.7). The OT is seen in 3 image. 2017-10-23 00:21:37 m_OT=19.8+-0.3 2017-10-23 00:25:18 m_OT=19.5+-0.2 2017-10-23 00:32:51 m_OT~20.0+-0.5 2017-10-23 01:29:45 no OT up mlim=20.8 There is no minor planet at this place. There is Wise source in 1.4 VIZIER database, so it can be UVCet flare We have reference image on 2016-09-08.13229 UT with unfiltered mlim=20.3m.
