In the night of 2020-02-13, we first observed the 16 NED galaxy fields
of LIGO/Virgo S200213t (GCN #27042) + IceCube neutrino candidate (GCN
#27043), as reported in GCN #27047, using the NEXT 0.6m optical
telescope, located at Nanshan, Xinjiang, China. Observations started at
13:19:16 UT and ended at 14:27:36 UT in the Sloan r-filter, and each
field was imaged twice with 90 sec for each exposure. Typical limiting
magnitude is r~19.0.
Subsequently we observed 120 GLADE galaxy fields that are selected
according to the probability skymap of LIGO/Virgo S200213t, the galaxy
distance within the 3sigma limit, the B-band absolute magnitude for the
galaxy < -18, as well as the observable altitude > ~20 deg. Observations
were again taken in the Sloan r-filter, with 90 sec for each exposure.
Typical limiting magnitude is r~19.0.
The list of the observed galaxies is given below.
