Constraint Details
Monitor: Y
Criteria: We request weekly 5 to 10 ks, as schedule allows, until the source becomes sun-constrained for NICER which will occur rather soon. The remainder of the exposure could be utilized in February and March (repair and schedule permitting). Then, we request bi-weekly exposures of 5-10 ks. We shall terminate this monitoring program if the latter indicates that the source has returned to quiescence.

Description: Proposal 7082 requests 100 ks of NuSTAR time, which we hope to be split into 2x50 ks, scheduled towards the end of October and November, respectively. We understand it will be complex to schedule quasi-simultaneous NICER observations. This is okay, since the outburst is observed mainly at >2 keV, the two telescopes are complementary and could provide a more complete coverage to the outburst
