IAU COMMISSION 27 UNPUBLISHED DATA FILE 98 3 pages, including cover sheet June, 1982 PHOTOELECTRIC V OBSERVATIONS OF ALGOL Photoelectric V observations relative to the comparison star Pi Persei are presented. The observations were corrected for differential atmospheric extinction and transformed to the V of the UBV system. The telescope used was an 8-inch f/6 Newtonian with an Optec photometer which uses a PIN silicon diode instead of a traditional photomultiplier tube. A 2.9 arcminute diaphragm was used. 3 pages, including cover sheet Gary A.
