Fermi-LAT Gamma-ray Observations of Recurrent Nova V745 Sco
Abstract
We report Fermi Gamma-ray Space Telescope observations of the recurrent nova V745 Sco discovered in outburst on 2014 February 6.694 UT (CBET 3803). Preliminary analysis of the Fermi-LAT data indicates the largest observed significances on Feb 6th and 7th of 2 and 3 sigma, respectively, with a peak daily flux, F(E>100 MeV) ~ (3 +/- 1) x 10^-7 ph cm^-2 s^-1 (statistical error only; photon index of 2.2 was assumed).
