V404 Cyg in outburst
Posted: Sun Jun 28, 2015 7:30 pm
Dear All,
V404 Cyg is going into outburst.
Dr Olivier Godet (Midi-Pyrénées Observatory, France) asks for spectra.
He adds the following information : the last eruption occured more than 20 years. It is a very bright X ray source (more than 40 - 45 times the Crab Nebula). A multi-wavelength campaign is active from radio to gamma wavelength. My collegue Mickael Coriat contributes to the radio monitoring of this source, which is of special importance for the research of our team.
A spectroscopic survey is of very high interest. The position of V404 Cyg is :
RA(J2000) = 20:24:03.78; Dec(J2000) = +33:52:03.2.
If possible, in accordance with the magnitude of the object, short integration times are welcome to monitor the temporal evolution.
Spectra at low and high resolution must be sent to francoismathieu.teyssier at bbox.fr for inclusion in ARAS Data base
Clear Sky !
