Comet C/2022 E3 (ZTF) was quickly identifiable in the raw images at approximately magnitude brighter than 5 (compare to HD 42818 to its immediate 10 o' clock). Despite being in naked eye range on an usual night, the nearby Moon illluminated at 87% and a persistent variable cloud layer on this cold night (T=2C) did not make it possible for me to spot it. The green tint was more obvious than on previous nights in the raw files.
