Monitor: Y
Criteria: 4U 1705-44 expected to observe on two occasions for 10 ks each. The interval between successive observations is 7 days. The two 10 ks NICER observations can be spread over the simultaneous AstroSat observations.
Phase Dependent: N

End: 2020-08-15 12:16 UTC
Remarks: The two 10 ks NICER observations can be spread over the AstroSat observations, but it should strictly fall in the AstroSat observing windows in order to get the simultaneous data. The expected dates of AstroSat observations are, Epoch 1: 2020Aug07 at 23:56:31 (MJD 59068.99758102) Epoch 2: 2020Aug14 at 23:56:31 (MJD 59075.99758102) We will confirm the exact observing windows as soon as possible.

Coordinate Observation: Y
Observatory: ASTROSAT
Description: RXTE was the workhorse in the field of rapid time variability during 1996-2012. Now, LAXPC instrument onboard AstroSat effectively replace RXTE and contributing to the rapid variability studies in the 3 80 keV energy band. The large effective area and superior time resolution make the LAXPC an ideal instrument to explore the timing properties of XRBs in the hard X-ray band.
