Specific Time: Y

Start: 58731.890
End: 58731.920
Remarks: While only one time range is specified above, in actuality we suggest two time ranges: 58731.89050926 - 58731.92013889 58733.88981481 - 58733.91967593 These time ranges coincide with two specific NICER windows, selected in order to coincide with ideal observing times for HiPERCAM/GTC based on instrument availability, source altitude, and local night, and are strict as a result.

ToO: Y
Coordinate Observation: Y

Observatory: GRAN TELESCOPIO CANARIAS
Description: This observation will be in coordination with the HiPERCAM instrument on the Gran Telescopio Canarias. Correlated Optical/X-ray observation has previously proven highly useful in the analysis of X-ray Binary sources, and we therefore consider it very useful for the investigation of Aql X-1.

Uninterrupted: Y

Justification: Since HiPERCAM will also be observing, and each window is only 2.5ks in length, we hope that the two observations will be uninterrupted in order to maximise statistics for this source.

Estimated Count Rate (cts s-1): 3000.000
