SUBJECT: GRB 200215A: Liverpool Telescope upper limits

D. A. Perley and A. M. Cockeram (LJMU) report:

We observed the field of GRB 200215A (Bernardini et al., GCN 27079) with 
the IO:O imager on the 2m robotic Liverpool Telescope between 19:56 and 
20:14 UT on 2019-02-15.  We acquired 3x150s exposures in each of the i 
and z filters.  No counterpart is detected within the XRT error circle 
in either filter.  Calibrating relative to nearby standards from the 
Pan-STARRS 1 catalog, we place upper limits (3-sigma) of:

i > 22.90  (t = 0.2204 days)
z > 21.95  (t = 0.2264 days)
