- Аннотация: MASTER OT J200308.64+023410.4 discovery - dwarf nova outburst, ampl>5.6m MASTER-IAC auto-detection system (Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L) discovered OT source at (RA, Dec) = 20h 03m 08.64s +02d 34m 10.4s on 2016-06-02.14910 UT with unfiltered m_OT=16.3m (mlim=18.8m). There are 9 images with OT.We have reference image without OT on 2015-10-12.82019UT, unfilt. mlim=19.7m (MASTER unfiltered W is calibrated to USNO-B1 as 0.2B+0.8R). There is GSC star with only blue 21.32(22mag POSS limit to Red), i.e.ampl>5.6m. The discovery and reference images are http://master.sai.msu.ru/static/OT/200308.64023410.4.png MASTER OT J180241.86+090312.9 discovery - dwarf nova, no VIZIER data, ampl>3.8m MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 18h 02m 41.86s +09d 03m 12.9s on 2016-06-05.13306 UT with unfiltered m_OT=18.2m(mlim=19.6) The OT is seen in 10 images.There is reference image without OT on 2016-03-10.19389 UT mlim=19.9m. There is no known sources in VIZIER database, it means 22m POSS limits and ampl>3.8m. The discovery and reference images are http://master.sai.msu.ru/static/OT/180241.86090312.9.png MASTER OT J130523.22-033819.6 discovery - dwarf nova outburst, ampl>3.3m MASTER-SAAO auto-detection system discovered OT source at (RA,Dec)=13h 05m 23.22s -03d 38m 19.6s on 2016-05-30.810UT with unfiltered m_OT=18.7m(mlim=20.3). The OT is seen in 4 images. We have reference image without OT on 2015-05-21.89800 UT with unfiltered magnitude limit 19.6m. There is no known VIZIER sources. The discovery and reference images are http://master.sai.msu.ru/static/OT/MASTEROTJ130523.22-033819.6.jpg MASTER OT J190901.75-343617.3 discovery - UG outburst,ampl>5.1m MASTER-SAAO auto-detection system discovered OT source at (RA, Dec)=19h 09m 01.75s -34d 36m 17.3s on 2016-06-02.08521UT with unfiltered m_OT=16.9m(mlim=19.3). The OT is seen in 3 images. There is no USNO-B1 star, it means the 22m upper limit to minimum and ampl>5.1. There is GSC2.3.2 star and GALEX source =>accretion to white dwarf, i.e. UG. We have reference image without OT on 2015-05-19.97662UT, mlim=19.5m. MASTER OT J145949.09-194555.3 discovery MASTER-IAC auto-detection system discovered OT source at (RA,Dec)=14h 59m 49.09s -19d 45m 55.3s on 2016-06-02.03126UT with unfiltered m_OT=17.8m (limit 19.6m). There are 3 images with OT.Reference image without it is on 2016-04-13.03639UT, mlim=19.6m. The discovery and reference images are http://master.sai.msu.ru/static/OT/145949.09-194555.3.png MASTER OT J194732.04+405021.8 discovery MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 19h 47m 32.04s +40d 50m 21.8s on 2016-06-03.91119 UT with unfiltered m_OT=17.3m(mlim=18.7m). The OT is seen in 6 images. We have reference image without OT on 2014-09-03.78622UT,mlim=19.5m. The discovery and reference images http://master.sai.msu.ru/static/OT/194732.04405021.8.png Spectral observations are required for all OT.
