TeV Observations of Markarian 501 with the Milagrito Water Cerenkov Detector
The Milagrito water Cerenkov detector near Los Alamos, New Mexico, was operated as a sky monitor at energies of a few TeV between 1997 February and 1998 May, including the period of the strong, long-lasting 1997 flare of Markarian 501. Milagrito served as a test run for the full Milagro detector. An event excess with a significance of 3.7 from Markarian 501 was observed, in agreement with expectations.
