Start: 2022-10-23 00:00 UTC
End: 2022-10-24 00:00 UTC
Remarks: The requested observation should be performed simultaneously with the planned NuStar observations (see below), which will overlap with a planned MeerKAt observation.

ToO: Y
Coordinate Observation: Y

Observatory: NUSTAR AND MEERKAT
Description: NuStar allocated time slots: 90802322004 XTE_J1701m462 255.242900 -46.186000 2022:267:16:40:05 2022:268:03:45:00 8 19.5 90801022002 XTE_J1701m462 252.742900 -46.686000 2022:268:03:55:57 2022:268:08:45:00 4 10.5 MeerKAT will observe for 1000s at some point in the above time slots (detailed planning still unavailable).

Uninterrupted: Y

Justification: Obtaining a number of consecutive orbits is crucial to properly trace the source evolution in the Hardness Intensity Diagram, especially given the difficulties imposed by the NICER soft response.

Estimated Count Rate (cts s-1): 1200.000
