We report on additional optical observations of the evolution of the type II supernova SN 2023ixf, which was discovered in May 2023 by K. Itagaki. Due to the relative proximity of the host galaxy Messier 101, that supernova received quite thorough multiwavelength coverage.
The supernova was serendipitously captured by Bernd Schneider while imaging the host galaxy from La Palma / Canary Islands on JD 2460083. CCD images were taken through a 65mm aperture at a focal length of 426mm and with an exposure time of 60s per frame.
Optical photometry of stacked L-band images was subsequently performed by Wolfgang Vollmann, and resulted in the following brightness values:
JD 2460083.42 17.12 +/- 0.12mag CV
JD 2460083.56 17.07 +/- 0.12mag CV
Comp. star: 14h 04m 21.68s +54°19'22.4" (2000.0) V = 11.948; B-V = +0.624
Check star: 14h 04m 42.12s +54°21'06.4" V = 12.319; B-V = +0.738
