Abstract

We present the results from an optical monitoring campaign aimed at studying theafterglow properties of the short GRB 100816A. We implemented a new way of processing theSwift-BAT data, and based on it we reclassified this burst as short,discarding the initial classification as long. Observations were carried out mainly withthe GTC Telescope within the four following days after the burst to investigate theoptical photometry of its afterglow, and a year later to localize the host. We completedthe optical imaging with the 1.23 m and 3.5 m CAHA Telescopes. We built and fitted thenIR-optical SED for the characterization of the host. The best fit of the SED(χ2/d.o.f. = 1.656) obtained for assumed values of a solarmetallicity, and an extinction of AV = 0.2mag is obtained fora starburst galaxy with a dominant stellar population aging about 360 Myr.
