The target - SN2026hkg - is being observed by ACIS-S for 4 hours and 10 minutes. The observation started 3 hours ago and ends in 1 hour, and is part of the proposal Mapping the most extreme mass-loss events from massive stars with Chandra+NuSTAR. The target is located in the constellation Volans. See related observations: 31144, 31145.
This is a joint observation with Nuclear Spectroscopic Telescope Array (NuSTAR) (for 1 day and 17 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.
