Fermi-LAT daily monitoring observations of the microquasar Cygnus X-1

Detection of gamma-ray emission from microquasars is important for understanding particle acceleration in the jet, and for constraining leptonic/hadronic emission models. We present a continuation of a 1-d likelihood analysis on gamma-ray observations by \emph{Fermi}-LAT (0.1--10 GeV) of the accreting black hole candidate Cygnus X-1. Combining this gamma-ray data with available X-ray monitoring data from \emph{Swift} and \emph{MAXI} allowed us to reveal four days (in a two-year period) on which Cyg X-1 displayed low-significance (3--4$\sigma$) excesses, three of which were contemporaneous with apparent transitions in the X-rays.
