Abstract

We have analysed the ALLEGRO data for the years 1999 and 2000 looking for continuous wave signals coming from some specific directions in the sky. No signal was found for these directions in long time integrations. However, we found a 'signal' at 919.535 Hz in a 50 min time integration search, which appeared on 13 August 1999 and disappeared on 12 December 1999. We present here the results of these searches and the reasons why we believe this 'signal' is probably noise.
