Description: We ask to coordinate the NICER observations in order to have the major numbers of visits at the time of the NuSTAR observations. NICER observations before and after the NuSTAR observations can be important for a better characterization of the source activity in X-rays during this flaring activity.
Uninterrupted: N
Justification:
Estimated Count Rate (cts s-1): 500.000
