New outburst of the accreting-millisecond X-ray pulsar NGC 6440 X-2
On Friday 19th, 2010 (19h 13m 26s UT), the RXTE galactic bulge scans detected a flux excess in the direction of the globular cluster NGC 6440. This globular cluster is known to harbor at least 24 X-ray sources (Pooley et al. 2002, ApJ 573, 184), of which two have been identified as accreting-millisecond X-ray pulsars (AMXPs): NGC 6440 X-2
