GRB 140206A optical counterpart: detection by the Virtual Telescope
On the night of 6 Feb. 2014, we tried to observe the optical counterpart of GRB 140206A, reported earlier that day. These afterglows fade quite quickly, but we tried anyway.
Several 300 seconds unfiltered exposures were taken with he PlaneWave 17″ robotic unit, easily recording the afterglow. Photometry and astrometry were promptly performed and shared with the GRB community via the Nasa’s Gamma-ray Coordinates Network (GCN).
Above is the average of 5 of those images and the preliminary analysis was published in the GCN 15801 circular.
The redshift of the source was estimated to be z=2.74, corresponding to a huge distance of 11.2 billions of light years.
