Mirzoyan et al. (ATel #5887) report the detection of an exceptionally
high state in the blazar 1ES 1011+496 from MAGIC and VERITAS
observations at > 100 GeV.
1ES 1011+496 corresponds to the Fermi LAT source 2FGL J1015.1+4925
(Ackermann et al. 2011, ApJ, 743, 171). Automatically generated
aperture photometry light curves of all sources in the Fermi LAT 2nd
catalog (2FGL) with 30 day time resolution and covering the energy
range 100 MeV to 200 GeV are provided by the Fermi Science Support
Center.
These are available at:
http://fermi.gsfc.nasa.gov/ssc/data/access/lat/2yr_catalog/ap_lcs.php
Automatic detection of flares in the aperture photometry is also provided at:
http://fermi.gsfc.nasa.gov/ssc/data/access/lat/2yr_catalog/ap_lcs_flares.html
We note that 2FGL J1015.1+4925 is detected in this analysis, and the
light curve shows 2FGL J1015.1+4925 to be the brightest seen so far in
over 5.5 years of LAT observations.
Although investigation of 2FGL J1015.1+4925 on shorter timescales is
hampered by the low flux of the source, an aperture photometry light
curve with 1 day time resolution is suggestive of a roughly linear
increase commencing on approximately MJD 56687 (2014-01-30), or
possibly sooner.
A determination of the source flux and spectrum awaits a fuller
analysis using techniques other than simple aperture photometry.
