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." 主題: 回覆： 人馬座新星 ASASSN-16ma probable nova (11.6 mag) 作者: peter 於 2016-11-08 18:23:18 http://www.starlab.ru/showthread.php?p=521456
