MAXI/GSC detection of renewed activity of the black hole candidate EXO 1846-031 after 34 years
Abstract
The MAXI/GSC nova alert system triggered on a hard X-ray transient at 20:44 UT on July 23 (http://maxi.riken.jp/alert/novae/8686724981/8686724981.htm). We also received the "Alert" (Negoro+ 2016, PASJ, 68, S1) from the system triggered at 21:05 UT on July 30. The source position is consistent with those of the SFXT IGR J18483-0311 and EXO 1846-031, which are about 16 arcmin apart.
