Abstract
The Haleakala 10m2 Cherenkov light telescope, which has an estimated energy threshold for gamma-induced atmospheric cascades of 2 x 1011eV, has observed the Crab pulsar, PSR0531, for a total of more than 211 hours. The results of analysis of 10% of this data are reported. Using standard methods of periodic analysis, pulsar periodicity consistent with radio ephemerides has been observed on at least two occasions. The light curve obtained exhibits both a primary and a secondary peak. Like other known astrophysical VHE gamma sources, this pulsar appears episodic in its emissions, with episodes lasting less than an hour.
