The interactive map shows the VLT Survey Telescope (VST) pointings of GW 151226 in GCN CIRC. 18734.
For each pointing the integrated probability is reported according to the BAYESTAR skymap issued in GCN CIRC. 18728.
In white the 90% the probability is mapped using the Multi Order Coverage approach (MOC).

We observed 72 square degree of the skymap of the advanced LIGO and Virgo trigger G211117, with the VLT Survey Telescope (VST) at ESO-Paranal equipped with OMEGACAM (FOV=1 square degree). The r SDSS filter was used. The observations are divided in 8 regions 3 x 3 square degree each, centered on the following coordinates RA, Dec (J2000):
The first group of observations on the North area started at 2015-12-28T01:14:02.794 UT and finished at 2015-12-28T04:00:48.959 UT, while the observations in the South area started at 2015-12-28T07:51:18.143 UT and finished at 2015-12-28T08:55:27.653 UT.
The image analysis is ongoing. Further observations of these fields are planned.
