LIGO/Virgo S200224ca: No counterpart candidates in TOROS observations

We report the following targeted observations in response to S200224ca conducted by the Cristina Torres Memorial Observatory (CTMO) in Brownsville, Texas: SDSS J113309.58-085247.9, RA: 173.289917 deg, Dec: -8.879995 deg SDSS J113813.09-113309.0, RA: 174.558000 deg, Dec: -11.552510 deg SDSS J113817.07-113633.2, RA: 174.574000 deg, Dec: -11.609180 deg SDSS J113440.11-074557.5, RA: 173.667145 deg, Dec: -7.765990 deg Observations were conducted on 2020-02-25 from 04:00 to 06:00 UT and 2020-03-01 from 04:00 to 09:00 UT using the CTMO CDK17 optical astrograph and ProLine 16803 CCD camera (43 arcminute FOV). For 02-25 observations, we took 10x30-second exposures in SDSS u'-band at 1x1 binning. For 03-01 observations, we took 15x60-second unfiltered exposures at 2x2 binning. Source search is ongoing and we will report any positive transient detection.
