In Alert Notice 826 I neglected to include the offset of the supernova. SN 2023ixf is located 227.7" east and 134.1" south of the center of M101.
Dear observers, do not forget please about rotator ASASSN-V J140119.59+541839.3 from the other side of M101. Close observing of SN gives a chance to get its phase plot as bonus.
Thanks for the info,
I just checked and ASASSN-V J140119.59+541839.3 is about 35 arcmins from SN 2023ixf. I was hoping I could process all my SN images I have taken so far for this star but my FOV is only 23 arcmins! Others with wider FOVs may be lucky.
I'll make a point of slewing to ASASSN-V J140119.59+541839.3 after I've grabbed the Sn.
I would like to encourage everyone who is observing in multi-color filters for this object and all others to learn how, do the work required, and to report transformed magnitudes. Yes, it is a bit more work, but the usefulness of the photometry to the astronomical community is greatly improved. The AAVSO DSLR and CCD Observing manuals have the methods and equations to use. If you are unsure how to transform your photometry ask for help in one of the appropriate forums, "Photometry" forum is suggested as the place to ask question on how to transform.
