Abstract
We report on the recent gamma-ray activity of the binary system PSR B1259-63 by the Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope. The source was detected by the LAT when the pulsar crossed the disk of the Be star in mid-Nov (Tam et al. ATel #3046; Abdo et al. ATel #3085). After the periastron in mid-Dec, the gamma-ray emission has decreased significantly. By using the LAT data taking between 2010-12-22 and 2011-01-14 UT, the source was not detected with a likelihood test statistic (TS) of 4.
