Monitored from Braniborg Tower Observatory (BTO), Zielona Gora, Poland and Skinakas Observatory (SKO), Crete, Greece
We monitor supernova SN 2011dh that exploded in M51 in late May 2011. We are using both a 14-inch Meade LX200 telescope equipped with an SBIG ST-8XE CCD camera from BTO and the 1.3 m telescope in Skinakas Observatory. In BTO, we use either a clear filter and calibrate the images to SDSS g-band (with an alignment of 0.02 mag rms) or the V Bessel filter (not in the table yet). In SK, we use B, V, R, I, and H alpha filters.
