In 1982, minima of the
short-period eclipsing binary V1010 Ophiuchi were found to occur more than 2.5
hours earlier than predicted by the light elements in the 3rd edition of the
General Catalog of Variable Stars (GCVS). Twenty-six visual and photoelectric
times of mid-eclipse during 1982-1986 are reported. O-C residuals from revised
light elements in the 4th edition of the GCVS remain significant, and improved
elements by Williams and Guinan are noted. The observations also indicate a
time-keeping or calculating error in the times of minima given by Hamdy et. al.
in IBVS 2818.
