The target - NVSS J081604-235003 - is being observed by ACIS-S for 4 hours and 43 minutes. The observation started 2 hours ago and ends in 3 hours, and is part of the proposal Confirmation of a Quiescent Galactic Black Hole. The target is located in the constellation Puppis and is a Radio Source. The source is so bright in X-rays that only one-eigth of the chip is used for the observation. More information on the target can be found at SIMBAD.
This is a joint observation with National Radio Astronomy Observatory (NRAO) (for 12 minutes and 30 seconds). However, it does not necessarily mean that the observations will be done at the same time!
