Remarks: The NICER time range below are selected in order to coincide with the strict observing times for HiPERCAM/GTC. Night beginning 12 and 13 May.
ToO: Y
Coordinate Observation: Y
Observatory: GRAN TELESCOPIO CANARIAS
Description: This observation will be in coordination with the HiPERCAM instrument (sub-second multi band imaging CCD) on the 10.4m Gran Telescopio Canarias. Correlated Optical/X-ray observation has previously proven highly useful in the analysis of X-ray Binary sources.
Uninterrupted: Y
Justification: We have been allocated 2x3.6ksec HiPERCAM observations 12 and 13May. Ideally we want the optical/X-ray observations to overlap for as long as possible. Our minimum uninterrupted observation is 1.5ksec
Estimated Count Rate (cts s-1): 6.000
