We report V-band photometric observations of SN2023ixf using different size telescopes, namely the 80mm UV/IR+CMOS, India, 330mm Lum+CMOS, USA, 80mm Lum+CMOS, USA and 610mm Vasistha telescope at IERCOO, Sitapur, ICSP, Kolkata. The reported magnitudes also include those obtained from pre-discovery images obtained by D. Singh from Amarkantak, India The supernova was discovered by K. Itagaki on 2023-05-19.727 UT. Photometric calibrations are done using Tycho software and ATLAS catalogue. More details can be found here https://posts.3cepheids.co.in/wp/photometry/photometric-light-curve-sn2023ixf-m101/
