Description
We report on the observation of the region around supernova remnant
G65.1+0.6 with the stand-alone MAGIC-I telescope. This region hosts the
two bright GeV gamma-ray sources 1FGL J1954.3+2836 and 1FGL
J1958.6+2845. They are identified as GeV pulsars and both have a
possible counterpart detected at about 35 TeV by the Milagro
observatory. MAGIC collected 25.5 hr of good quality data and found no
significant emission in the range around 1 TeV. We therefore report
differential flux upper limits, assuming the emission to be point-like
(<=0fdg1) or within a radius of 0fdg3. In the point-like scenario,
the flux limits around 1 TeV are at the level of 3% and 2% of the Crab
Nebula flux for the two sources, respectively. This implies that the
Milagro emission is either extended over a much larger area than our
point-spread function or it must be peaked at energies beyond 1 TeV,
resulting in a photon index harder than 2.2 in the TeV band.
