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 Ic∼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.
