MAXI/GSC detects an outburst from a Be/X-ray binary GX 304-1
Abstract
An X-ray increase from the Be/X-ray binary pulsar GX 304-1 was observed with MAXI/GSC on 2010 August 6 (MJD 55414.5) at 58+-5 mCrab (4-10 keV). This is consistent with the recurrent outburst from this source with a 132-day period since the last one on 55289.5 (= April 3, 2010) (ATel #2538). This is the sixth of successive outbursts following 28 years absence. The peak flux has been gradually increasing for the last five outbursts.
