We are continuing our C17 program, and will target a single bright x-ray nova in the bulge of M31. This is a joint program with Chandra, and the Chandra AO12 TAC assigned the HST time.

We will trigger based on discovery of a transient with Chandra, and then follow up with another 2 orbit observation 6 months later. The target co-ords will be updated at the time of the trigger. 12 false 0.0 0.0 false false false false SUPPORTED GALAXY BULGE position to be updated 3 to 4 weeks before observation.
