Abstract:
We present the early multiband evolution of SN 2023ixf made from the observations of the Observadores de Supernovas (ObSN, Spain).

We present the early photometric evolution of SN 2023ixf made from the observations of the Observadores de Supernovas (ObSN, Spain). This light curve begins with the data obtained by our observers from the same night (HJD 2460084.45402) of its discovery by Mr. K. Itagaki until last night (HJD 2460087.42115). For this, telescopes located in private observatories spread throughout the Spanish geography and Italy have been used. CCD detectors with Johnson/Cousin BVRI and Sloan g', r', i' filters have been used. In the light curve, the rapid increase in the initial brightness of the supernova (>2 mags. in 1 day) can be observed, as well as a lower cadence in its ascent since it must be close to reaching its maximum. You can collect more information on the monitoring we are carrying out on the group's website: www.obsn.es
