The target - NGC 6099 - is being observed by ACIS-S for 6 hours and 56 minutes. The observation started 7 hours ago and ends in 3 minutes, and is part of the proposal X-ray emissions of a peculiar hyperluminous X-ray source. The target is located in the constellation Hercules and is a Radio Galaxy. More information on the target can be found at SIMBAD. See related observation: 32300.
This is a joint observation with Hubble Space Telescope (HST) (for 1 hour and 23 minutes). However, it does not necessarily mean that the observations will be done at the same time! This is a time-critical observation.
