- Аннотация: MASTER OT J181909.82+253407.7 discovery - dwarf nova outburst, ampl>6m MASTER-Kislovodsk auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 18h 19m 09.82s +25d 34m 07.7s on 2018-04-04.88163 UT during inspection. The OT unfiltered magnitude is 16.0m (limit 17.6m). The OT is seen in 3 images in MASTER-Kislovodsk. This OT was also detected by MASTER-IAC auto-detection system on 2018-04-04 06:01:15.291UT with unfiltered m_OT=16.0 and by MASTER-Amur on 2018-04-03 16:08:08.021UT with unfiltered m_OT=16.4. There are reference images without OT on 2017-11-27 16:04:16UT with unfiltered mlim=19.5, on 2012-04-30.02567 UT with unfiltered mlim=19.9m. There is only Pan-STARRS optical source(Chambers+, 2016) with rmag=21.40,gmag=21.51 on 2012-07-10 13:03:49UT in VIZIER database, it means 22m POSS limit and more then 6m of current outburst amplitude. . Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/MASTEROTJ181909.82+253407.7.jpg
