G. Masi, the Virtual Telescope Project - Italy, reports:
I started observations of GRB 140709A (Hagen et al. GCN 16546) with the 17"
robotic unit part of the Virtual Telescope (Ceccano, Italy) at 02:04:00 UT, 3000
seconds after the burst.
An optical source is visible where described by Castro-Tirado et al. (GCN 16554)
in a image coming from the sum of three, 180-seconds exposures, unfiltered. The
position of the source is RA: 20h18m38.94s +51d13'29.9" (J2000.0, mean residuals
of 0.2") and the magnitude was estimated to be 21.0, assuming R mags for the
reference stars from UCAC-4.
