Target Info

Target Name: 1A 0535+262
Target No.: 5035
Category: X-RAY BINARIES
Coordinates[J2000]: (84.72740, 26.31579)
Exp (ks): 40
Extended: N

Extent Size:

Background Restriction: N

Remarks:

Constraint Details

Monitor: Y

Criteria: Our NICER monitoring campaign should consist of daily visits of duration 2 ks beginning March 21, 2020. Near peak luminosity we request twice daily 2 ks integrations. As the source fades after peak we request continuation of 2 ks daily integrations until X-ray activity ceases.

Phase Dependent: N

Specific Time: Y

Start: 2020-03-21 00:00 UTC
End: 2020-05-04 00:00 UTC
Remarks: We set the start time for our monitoring well before the expected Type I outburst peak. This allows us to cover the Type I burst rise in detail. We hope the next outburst will be very bright and has long duration. If this is the case, we will want to adjust the NICER observation cadence to obtain a maximum science return for this TOO.
