The Galactic microquasar Cygnus X-3 is presently undergoing a flaring state following a two month quiescent phase (ATEL #12510). This has been covered in the radio (ATEL #12668, #12700, #12701) and the gamma-rays (ATEL #12678).
We have observed the source from the X-ray observatory Astrosat, on 30 April-01 May, 2019. The SXT spectra reveals a flux level of about 260 mCrab in the range 0.3 - 8.0 keV. The same observation was also undertaken using the wide band X-ray detectors LAXPC and CZTI.
Coordinated multi-wavelength observation of this source in the present flaring state is encouraged and solicited.
