(U. of Virgin Islands) on behalf of a large collaboration report:
One LCO 1-m unit at Siding Springs Observatory began observing Swift GRB
180624A (Gibson et al. GCN 22832) on June 24, 14:18 UT (28.5 min since
the GRB trigger time) with the SDSS r filter. Within the enhanced
Swift-XRT error circle (Goad et al. GCN 22835) we find an uncatalogued
object with a magnitude of r'=19.92 +- 0.10 (AB) at a mid time of 0.54
hours since the GRB trigger time at the following position:
RA(J2000) = 21:12:23.38
DEC(J2000)= -02:20:16.7
with an error radius of ~1".
