We report ACIS-S 20ks Chandra X-ray observations of supernova SN 2023ixf in M101. Our observations took place on May 31, 2023, 15:35 UT under the approved DDT proposal # 24508911 (PI: P. Chandra, Chandra ObsId 27862, https://doi.org/10.25574/27862).
SN 2023ixf is clearly detected with a count rate of (3.56+/-0.14)E-2 ct/s. Our data are best fit with a plasma of temperature ~10 keV and a column density of ~3.2E22 cm-2. As the temperature is at the edge of Chandra sensitivity limit, the temperature is not very well constrained. However, the column density certainly seems to have evolved as compared to the one reported by Grefenstette (ATel # 16049) based on the NuSTAR data taken on 2023 May 22. Our 0.3-10 keV unabsorbed flux is (1.6+/-0.1)E-12 erg/cm2/s, which corresponds to a luminosity of 8E39 erg/s for a distance of 6.4 Mpc.
More observations are planned.
Scientific results reported in this telegram are based on observations made by Chandra X-ray observatory.
