The target - AT2026dbl - is being observed by ACIS-S for 8 hours and 20 minutes. The observation started 2 hours ago and ends in 6 hours, and is part of the proposal Testing the limit: broad-band X-ray observations of the fastest and most luminous optical transients. The target is located in the constellation Cancer. See related observations: 31147, 31148.
This is a joint observation with Nuclear Spectroscopic Telescope Array (NuSTAR) (for 1 day and 12 hours). However, it does not necessarily mean that the observations will be done at the same time! This is a time-critical and monitoring observation.
This is an observation from a TOO (target of opportunity) proposal.
