Monitor: Y
Criteria: We propose 10 observations spread as uniformly as possible (ideally separated by 27 ks intervals but 50% variations in these interval are Ok) over the 363.9-ks time span of NusTAR observation which starts at 2022:099:22:45:11 (MJD 59678.94804398) and ends at 2022:104:03:50:00 (MJD 59683.15972222).

Coordinate Observation: Y
Observatory: NUSTAR
Description: NuSTAR will be performing 363.9 ks observation (covering the entire binary period) of LS 5039. NuSTAR sequence ID is 30701024002. NuSTAR observation will have occultation gaps with the maximum width of 3 ks. Our 10-ks long NICER observations will ensure significant overlap with the NuSTAR on-target time.
Uninterrupted: N
Justification:
Estimated Count Rate (cts s-1): 1.000
