We report the first results of a program to monitor the tidal disruption event candidate AT2022cmc (ATEL #15232) at a mean frequency of 90 GHz using MUSTANG2 on the Green Bank Telescope. Our first observation, on the 27th February, found AT2022cmc to have a flux density of 3.7+-0.4 mJy. Preliminary analysis of a second observation with GBT/MUSTANG2 on 2022 March 04 indicates a decline in flux density at 90 GHz. Further observations are planned with an approximately weekly cadence (weather permitting).
We gratefully acknowledge the GBT director and staff for the DDT and observing support that enabled these data.
