Pre- and post-discovery observation of SN 2011fh. Clear filter magnitudes from the CHASE Survey and from amateurs are plotted as V-band, a single w-band LCOGT observation as R-band, and the 2016 HST F814W observation as I-band. Observations from different instruments are plotted with different symbols. The late-time luminosity level is marked with a dashed line. A zoom onto the rise to the 2011 event is plotted in the inset window, showing the first year of decline, during which a second, smaller peak is visible at +250 days.
