Quote:
"ASASSN-16ma was discovered in images obtained on 2016-10-25.02 at V~13.7 and proceed to brighten to V~11.6 a day later (UT 2016-10-26.02). We do not detect (V>17.3) the object in images taken on UT 2016-10-20.04 and before. No previous outbursts are detected at this location since ASAS-SN started observing the Galactic center in March 2016."
