H1 was taken out of Observing due to SQZ TTFSS Beatnote continuing to drop (even after the TTFSS box was swapped this afternoon [alog77734]). Lowered the Beatnoe RF Minimum from -12 to -20 to give us a few hours.
SDF with new minimum accepted (see screenshot of SDF, trend of beatnote since the Tues & today TTFSS swaps, and TTFSS medm).
