Date SubmittedJan. 14, 2023

Per Alert Notice 808, the blazar 4C 31.03 is undergoing an outburst. I would like to obtain images each in V,B,R (or sr) nightly with three 60-second or 120-second exposures in each filter (or length best for telescope that is available) nightly, if possible, beginning as soon as possible through January 22, 2023. If telescope time is not available for the full period, I would be happy with a single night's run of three images in V.

Thank you,
Stan Howerton (HSW)

Just got the first data, and realized it was wrong field. When copying from VSX the RA is 18.20971 in degrees. The RA is 01h12m50.33 which would 1.21398 if I am figuring this correctly now. My apologies. HSW
