Chris (preliminary): Just continuum - probably a BLac.
Isobel (preliminary): I agree - featuress blue thing.
Chris (final): FBT = Featureless blue thing
Andy (final): The SN is at the center of what looks like an E galaxy from the discovery image, so it is probably an AGN. Then again, it could be an early type II if the host is not an E galaxy. See, e.g. SN 1979C at +7 days, SN 1993J at +3, etc.
