- Аннотация: MASTER OT J002844.97+233329.3 discovery - OT during GRB180113B (IPN) inspection During GRB180113B (IPN triangulation) inspection (Svinkin et al. GCN #22354, IPN map ) MASTER-Kislovodsk auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 00h 28m 44.97s +23d 33m 29.3s on 2018-01-14.64970 UT. The OT unfiltered magnitude is 19.3m (limit 19.8m) The OT is seen in 2 images (MASTER IPN inspection mode) at 2018-01-14 15:35:34UT +180s exposition 2018-01-14 15:51:47UT +180s exposition There is no minor planet at this place. MASTER-Kislovodsk reobserved it automatically on 2018-01-16 15:32:23UT with m_lim=20.1(no OT). We have reference image without OT on 2014-09-30.90519 UT with unfiltered magnitude limit 20.5m. There is Sloan disk galaxy in 1.48" with rmag=20.08 Deep photometry is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/002844.97233329.3.png MASTER OT J141021.86+391928.4 discovery - PSN during Fermi/Maxi long GRB180116A inspection During Fermi trigger inspection (Stanbro et al. GCN #22356, also publishied as MAXI/GSC GRB, see Kawai et al. GCN #22347) MASTER-Kislovodsk auto-detection system discovered optical transient - possible supernova - at (RA, Dec) = 03h 00m 57.16s -66d 25m 23.1s on 2018-01-11.89176 UT. The OT unfiltered magnitude was 18.3m (mlim=19.5) on 2 images. This OT is in 1.2" of Sloan galaxy with rmag=20.6 http://skyserver.sdss.org/dr9/en/tools/quicklook/quickobj.asp?id=1237662195072565919 (2 sources). MASTER-Tavrida reobserved it at 2018-01-25 00:08:46UT with unfiltered m_OT=17.8 (mlim=19.9) We have reference image on 2015-02-27.01593 UT with unfiltered mlim= 20.5m. Spectral observations are required.

The OT unfiltered magnitude is 16.7m (mlim=18.9m). The OT is seen in 3 images. There is no minor planet at this place. Spectral observations are required.

The OT unfiltered magnitude is 19.1m (limit 20.1m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2015-04-16.85825 UT with unfiltered magnitude limit 20.6m. Spectral observations are required.
