- Аннотация: MASTER OT J172540.91+114744.4 discovery - Novalike (NL) type of variability MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 17h 25m 40.91s +11d 47m 44.4s on 2015-05-10.96431 UT. The OT unfiltered magnitude is 18.0m (limit is 19.1m). There are 10 images with OT on 2015-05-(10.951 - 10.974) in MASTER-SAAO database. There are about 200 images with this OT in MASTER-Amur, Tunka and Kislovodsk databases since 2010-04-21.044UT as well as on the CRTS since 2006-06-18 (17.65 CV). But. There is no object at the position on the POSS I and POSS II images. So we assume Novalike (NL) type of variability for this MASTER OT. Spectral observations are required. The discovery images are available at https://master.sai.msu.ru/static/OT/MASTER172540.91114744.4.jpg
