During recent observations of the Galactic Plane (PI: A. Bazzano) weak hard X-ray emission was observed from the accreting millisecond X-ray pulsar MAXI J0911-655/Swift J0911.9-6452 in the globular cluster NGC 2808.
MAXI J0911-655 was detected by IBIS/ISGRI at 6.3 sigma during revolution 2381, between 2021-06-26 05:04:08 UTC and 2021-06-27 05:47:50 UTC, and during revolution 2384 between 2021-07-04 01:05:45 UTC and 2021-07-05 04:54:35 UTC with a combined effective exposure time of 6.9 ks. The 22-60 keV IBIS/ISGRI flux corresponds to (12.3 ± 2.0) mCrab.
All the data have been analysed using the Offline Software Analysis version 11.0 (OSA11). Results from the Galactic Plane Scanning are publicly available at: http://gps.iaps.inaf.it./
