GRavitational Wave Inaf TeAm report:
Observations of 1 square degrees of the skymap of the Advanced LIGO
and Virgo trigger G298048 (LVC GCN Circ. 21509, 21513) were performed with
the VLT Survey Telescope (VST - Proposal ID ESO 099.D-0191) at ESO-Paranal
equipped with OMEGACAM. The observations are centered on the galaxy
NGC4993. The images were taken in the i_SDSS filter with a total exposure
of 1200s. The observations started at 2017-08-31T 23:22:12.442 UTC and
finished at 2017-08-31T 23:39:26.585. The Optical Transient (OT) is not
visibile in the coadded image. The completeness at 50% for point-like
sources is 22.53 AB mag. Automatic data reduction with the VSTTube
pipeline (Grado et al. 2012 Mem.SAIt 19, 362 ) was completed.
We acknowledge excellent support from the ESO User Support Department and
from ESO observing staff in Paranal.
