The target - NGC 1358 - is being observed by ACIS-S for 4 hours and 10 minutes. The observation started 2 hours ago and ends in 3 hours, and is part of the proposal A joint Chandra and NuSTAR monitoring of a changing-look Compton thick AGN. The target is located in the constellation Eridanus and is a Seyfert 2 Galaxy. More information on the target can be found at SIMBAD
. See related observation: 29936.
This is a joint observation with Nuclear Spectroscopic Telescope Array (NuSTAR) (for 20 hours and 50 minutes). However, it does not necessarily mean that the observations will be done at the same time! This is a time-critical and monitoring observation.
