We report imaging observations for the gravitational wave event S200213t (LVC, GCNC 27042). We started our observations from 2020-02-13 09:39 UT (MJD=58892.40) about 5 hours after the event and ended at 2020-02-13 15:57 UT (MJD=58892.66).
We performed galaxy-targeted observations for 23 galaxies (see the Table 1 below) selected from the GLADE catalog (Dalya et al. 2018) in the probability skymap of S200213t using the following telescopes and instruments. In addition, we also observed 7 candidates from the Zwicky Transient Facility (Kasliwal et al. GCNC 27051; Table 2) and, 14 galaxies selected from a combination of the IceCube localization (Hussain
, GCNC 27043; Table 3) and the GW probability map. In this GW+IceCube region a cumulative probability to have a GW source reaches 95% by assuming that the source resides in GLADE galaxies.
We found no apparent transients except for variable stars around these galaxies to 5 sigma limiting magnitudes in the AB system listed below.
