  The CELESTE experiment uses the heliostats of an old solar farm in the French
Pyrenees to detect gamma ray air showers by the atmospheric Cerenkov technique.
CELESTE has been operating since November 1999 with an array of 40 heliostats
fully instrumented with 1GHz flash ADCs.
  Significant advances have been made in the detector simulations and in the
data analysis techniques.
  We report here on results from recent observations of the Crab nebula above
an energy threshold of 50GeV.
  The results and simulations illustrate the current sensitivity of the
experiment.
