- Аннотация: MASTER OT J173432.09+191254.2 discovery - new OT, dwarf nova outburst, ampl>6.5mMASTER-Kislovodsk auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )during own survey detected new optical transient source at (R.A.,Dec 2000) = 17h 34m 32.09s +19d 12m 54.2s on 2022-01-20.14418 UT.The OT unfiltered magnitude is 15.7m (mlim=17.6m).The OT is seen in 3 images. There is no minor planet at this place.We have reference image on 2015-08-14.75668 UT with unfiltered mlim=21m.There is no known sources in VIZIER at this position.But there is non-catalogued blue OT at PanSTARR images, taking into account neighbouring faint stars with known rmag~22, the amplitude of current OT outburst is more then 6.5mag.Spectral observations are required.The discovery and reference images are available at:http://master.sai.msu.ru/static/OT/173432.09191254.2.pngMASTER OT J130738.14+210242.9 discovery possible UV CetiMASTER-Amur auto-detection system discovered the flash of OT source at (RA, Dec) = 13h 07m 38.14s +21d 02m 42.9s on 2022-01-19.67195 UT.The OT unfiltered magnitude is 15.4m (mlim=17.3m).The OT is seen in 2 images. There is no minor planet at this place.We have 1 images for this night without object 2022-01-19.66082UT with mlim=17.2m.We have also reference image on 2019-01-05.85213 UT with unfiltered mlim=17.1m, 2017-05-30 02:28:55UT with mlim=20.5m.The discovery and reference images are available at:http://master.sai.msu.ru/static/OT/MASTEROTJ130738.14+210242.9.jpg
