      PHOTOELECTRIC OBSERVATIONS OF V 1216 SGR DURING THE 
            1971, JUNE 16-30 INTERNATIONAL PATROL


According to the observing schedule of cooperative observations proposed by the
IAU Working Group on Flare Stars (Andrews et al. 1971, IBVS 516), V 1216 Sgr
was patrolled at the Catania Astrophysical Observatory for about 28.5 hours.

The observations were carried out with a 61 cm universal type reflector
feeding a synchronous u, b, v photometer.

The detailed coverage intervals are given in the accompaniing table. No
flare activity was detected during our patrol.

The explanation of symbols and details of the observing equipment can be
found in a preceeding number of this Bulletin (Cristaldi and Rodono, 1971, IBVS 525).
