The LCO 2-m unit at Haleakala Observatory (Hawaii), former FTN, began
observing Swift and INTEGRAL GRB 180626A (Evans et al. GCN 22850; Gotz
et al. GCN 22851) on June 26, 08:41:11 UT (20 min after the GRB trigger
time) with the SDSS ri filters. The optical counterpart (Evans et al.)
is clearly detected� with the following magnitudes:
