Remarks: We are planning to observe simultaneously at optical wavelengths. In order to maximise simultaneous X-ray/Optical coverage, we request to observe with NICER during the following time slots: 59700.69-59700.70, 59700.75-59700.76, 59700.81-59700.83, 59700.88-59700.89, 59701.72-59701.73, 59701.78-59701.80, 59701.85-59701.86, 59702.68-59702.703, 59702.75-59702.768, 59702.81-59702.83, 59702.88-59702.89
ToO: Y
Coordinate Observation: Y
Observatory: THAI NATIONAL TELESCOPE
Description: We have guaranteed observing time with the ULTRASPEC instrument mounted on the 2.4 m Thai National Telescope to perform simultaneous optical observations of 3FGL J1544.6-1125.
Uninterrupted: Y
Justification: We would like to sample the light curve at multiple wavelengths for the longest time possible as we would like to observe the transitions between the high and the low modes and also look for flares.
