- Аннотация: MASTER OT J180241.87+090312.9 discovery -PSN(18.4m) in 9.3E 11.7S of PGC135878(Btot=18.5) MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 18h 02m 41.87s +09d 03m 12.9s on 2016-06-05.16160 UT. The OT unfiltered magnitude is 18.4m (limit 19.1m).The OT is seen in 10 images. This PSN is in 9.3"E,11.7"S of PGC135878 (Btot=18.5) We have reference image without OT on 2016-03-10.19389 UT with unfiltered magnitude limit 19.9m. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/180241.87090312.9.png MASTER OT J031316.27-261217.0 discovery - new dwarf nova outburst, no VIZIER data, Ampl>5m MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 03h 13m 16.27s -26d 12m 17.0s on 2016-06-01.17642 UT. The OT unfiltered magnitude is 17.0m (limit 18.7m). The OT is seen in 4 images. We have reference image without OT on 2015-02-18.79714 UT with unfiltered magnitude limit 20.5m. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/031316.27-261217.0.png MASTER OT J204719.21+074704.8 discovery - new dwarf Nova outburst, Ampl>5.4m MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 20h 47m 19.21s +07d 47m 04.8s on 2016-06-06.17414 UT. The OT unfiltered magnitude is b>16.6m (limit 20.3m). The OT is seen in 2 images. There is no minor planet at this place. There is no known sources inside 4" in VIZIER database, but if one analyse the POSS blue and red images, you can see very faint marginally seen source, both in B and in R. Taking into account 22m limit, the amplitude of outburst is more then 5.4m. We have reference image without OT on 2015-09-04.92508 UT with unfiltered magnitude limit 20.6m. Spectral observations are required. The discovery and reference images are available at: http://observ.pereplet.ru/images/MASTEROTJ204719.21+074704.8.jpg MASTER-SAAO auto-detection system detects the following OTs (possibly red giants): MASTER OT J174845.03-283646.7 (unfiltered (0.2B+0.8R calibrated to USNO-B1) m_OT=14.7 at 2016-06-09 23:11:57.197UT, 6 images) and MASTER OT J174643.71-290652.6 (m_OT=17.5 on 2016-06-09 23:11:57.197)
