摘要：

The observation with the L3+C spectrometer of a three days lasting enhancement of cosmic ray muons originating from a fixed position in the northern sky is discussed. The "flare" was detected in a 2 degrees by 2 degrees sized sky cell with a chance probability of 2.6 center dot 10(-3). The signal exhibits a clear time evolution, persists up to muon energies above 50 GeV, suggests a neutral primary and was recorded within opening angles of 2.5 degrees down to less than 1 degrees. It happened between 51773.489 and 51776.333 MID (17-20 Aug. 2000). The origin is located at a galactic longitude of (265.02 +/- 0.42)degrees and a latitude of (55.58 +/- 0.24)degrees.
