The ongoing outbursts of Aql X-1 and Ginga 1843+009 as seen with INTEGRAL/IBIS-ISGRI
Abstract
Our INTEGRAL monitoring campaign of GRS 1915+105 allows the Aquila region of the sky to be nicely covered with the IBIS telescope. During our last observation, on March 18, 2009 (11h-16h45 UTC), both the LMXB Aql X-1 was clearly detected with the ISGRI camera at 17.5 sigma, 8.6 sigma, 6.6 sigma in the 18-40 keV, 40-80 keV, and 80-150 keV energy ranges respectively. This confirms the renewal activity of Aql X-1 mentioned in ATel #1970.
