Description

Supernova SN2013ej in M74

The frames were just calibrated with Darks,Flats and Darkflats with no elaboration or stretching. Then a photometric calibration was done using UCAC4 (APASS V) and AAVSO chart for calibration of visual magnitude (Aperture photometry). The calibration error can be estimated as +/- 0.15 magnitude, that big error is due to lacking of Johnson V filter (a UV-IR cut filter was used instead). Anyway the estimated visual magnitude is 12.5 +/- 0.15 that should be compared with the reported magnitude, for the same day, in AAVSO that is 12.5 +/- 0.1.
