The target - 2MASX J22373491-1925343 - was observed by ACIS-S for 3 hours and 20 minutes, ended 25 minutes ago, and is part of the proposal The First Serendipitous Dual [Ne V] AGN: Probing Obscured Black Hole Growth with Chandra. The target - also called LEDA 855412 - is located in the constellation Aquarius and is a Seyfert 2 Galaxy. The source is so bright in X-rays that only one-eigth of the chip was used for the observation. More information on the target can be found at SIMBAD
. See related observations: 31316, 32491, 32493.
This was a joint observation with Hubble Space Telescope (HST) (for 33 minutes and 20 seconds). However, it does not necessarily mean that the observations were done at the same time!
