Integrating from 2010-11-16 6 50 UT to 2010-11-17 09 15 UT, a preliminary quicklook maximum likelihood analysis yields a source flux of F = (2600 +/- 400)e-8 ph/cm2/sec (E > 100 MeV), which represents an increase by a factor of ~ 4 in 24 hours.Request for ObservationsAGNBlazarQuasarTransienthttp://adsabs.harvard.edu/abs/2010ATel.3034....1S2010ATel.3034....1S
