Abstract
In the last 12 years NGC 2770 hosted 2 standard supernovae (SNe) and one X-ray transient event (SN2008D) similar to a Gamma-Ray Burst (GRB). Given the close (27 Mpc) distance of NGC 2770, we could resolve with the OSIRIS tunable filter (TF) the 3 explosion sites in Hα. We also show Hα data of its satellite galaxy NGC 2770B, one of the least metallic galaxies in the local Universe.
