Scientific paper

We report on a Chandra Director's Discretionary Time observation of the type IIn SN 2005kd (IAUC 8630) which was performed on 2007-03-04.61 (UT). In the 3.0 ks ACIS-S3 observation, we detect 66 counts from the location of the SN. The X-ray emission is extremely hard. We fit an absorbed power-law model to the extracted spectrum, constraining the total column density to be at least equal to the Galactic value of 1.49e21 cm^-2 (Dickey & Lockman 1990).
