Referred to by ATel #: 11974

We observed the field of SN2018EBT (ATel #11891, TNS Report No. 20792) with the Arcminute Microkelvin Imager Large Array(AMI-LA; Zwart et al. 2008; Hickish et al. 2018) at 15.5 GHz on 2018-07-24.92 for 4 hours.
We do not detect a source at the phase center, and we set a 3-sigma upper limit of ~110 uJy.

The custom pipeline REDUCE_DC (e.g. Perrott et al. 2015) was used to calibrate and flag the data, with 3C286 as the absolute flux calibrator and J2022-6136 as the interleaved phase calibrator.

We plan to continue monitoring this source and would like to thank the MRAO staff for carrying out these observations.
