Phase drifting relatively fast. Weather?
03:40 scan on 0252-474 shows rapid phase variation and amplitude dips. Seemon shows path noise has shot up to 2000 microns over the last ~10 minutes from ~500 microns, so atmospheric turbulence (usually worst in a diurnal sense at around this time of day) is the cause.
05:50 phase stability continues to be poor, so “untie” the array and keep only CA04 in the tied array.
