Target Info

Target Name: MAXI J1752-457
Target No.:
Category: X-RAY BINARIES
Coordinates[J2000]: (268.26900, -45.86600)
Exp (ks): 30

Constraint Details

Monitor: Y
Criteria: Three 10 ksec observations at intervals of 1 day each.
Phase Dependent: N
Epoch:
Period:
Min:
Max:
Remarks:
Specific Time: Y
Start: 2024-11-20 00:00 UTC
End: 2024-11-28 00:00 UTC
Remarks: The chosen time range aligns with the decay phase of the MAXI J1752-457 outburst, as observed by MAXI and NuSTAR. These dates are critical to capturing the rapidly evolving soft X-ray flux and potential state transitions. Observations within this window will provide the best opportunity to study the source while it is still sufficiently bright for NICER's sensitive instruments.
ToO: Y
Coordinate Observation: Y
Observatory: NUSTAR
Description: Coordination with NuSTAR to study the hard X-ray component, using its previous observations and planned follow-ups to complement NICER s soft X-ray capabilities.
Uninterrupted: N
Justification:
Estimated Count Rate (cts s-1): 700.000
