GRB 070610: Flares from a peculiar Galactic source

The majority of bright gamma-ray transients that we observe in the sky, are produced by extragalactic gamma-ray bursts (GRBs). However, we know that there are other kinds of sources that can produce intense bursts of high-energy photons within our own Galaxy. GRB 070610/Swift J195509+261406, being just 1 degree away from the Galactic plane, is one of these sources and presents a peculiar behavior, as it shows strong flaring activity that has been observed in the optical and near infrared. We have gathered multi-wavelength observations of GRB 070610 including optical, near infrared, millimeter and radio observations. Our dataset covers the time from 1 minute after the burst onset to more than 4 months later. Following the burst in the gamma-ray band, the source displayed more than 40 flaring episodes in the optical bands (reaching up to I-c similar to 15) over a time span of three days, plus a faint infrared flare that was observed at late times. After this time, the source slowly faded away until it became undetectable.
