Remarks: The MJD time intervals required for the simultaneous or very close observations with SiFAP2 are: 59754.708-59755.292 MJD 59755.708-59756.292 MJD 59756.708-59757.292 MJD 59757.708-59758.292 MJD
ToO: Y
Coordinate Observation: PREFERRED
Observatory: TELESCOPIO NAZIONALE GALILEO
Description: Simultaneous or quasi-simultaneous observations will allow extremely accurate studies of the phase-shift between X-ray and optical pulses. However, even a partial overlap between X-ray and optical observations, will guarantee to obtain good results.
Uninterrupted: N
