Photometry of the blazar PKS 0537-441
Listed in IVOA Registry (Virtual Observatory)
We present a large collection of photometric data on the blazar PKS 0537-441 in the VRIJHK bands taken in 2004-2009.
Description
At least three flare-like episodes with months duration and >3mag amplitude are apparent. The spectral energy distribution is consistent with a power law, and no indication of a thermal component is found.
We searched for short timescale variability, and an interesting event was identified in the J band, with a duration of ~25 minutes.
