  The MACRO underground detector at Gran Sasso Laboratory recorded 60 million
secondary cosmic ray muons from February 1989 until December 2000. Different
techniques were used to analyze this sample in search for density excesses from
astrophysical point-like sources. No evidence for DC excesses for any source in
an all-sky survey is reported. In addition, searches for muon excess correlated
with the known binary periods of Cygnus X-3 and Hercules X-1, and searches for
statistically significant bursting episodes from known gamma ray sources are
also proved negative.
