Tohban notes for Jan 30:
Ant 3 The Elevation drive gearbox had water in it and had rusted. The
motor has also seized. Awaiting Quote from Intertronics for
replacement gearbox
Ant 4 FE Temp is sometimes out of range--no solution yet.
Ant 5 has low VPOL power probably due to DCM issue
Report problems here:
16:42 UT: adc_plot.py was not running.
18:39 UT: Files are listed as being 'SOLPNTCAL' rather than 'Normal Observing'
in the 20250130 FDB file after the 1830 SOLPNTCAL. Stopping and
restarting the schedule (21:06UT) has fixed the problem.
Antenna availability: automatic assessment.
