Nutsinee's plot of the CPSs this morning revealed a bump in the ITMY ST2 H2 and V2 CPS around 80Hz. As I look thru time since then, it has dropped in frequency, now around 78Hz. Two and three days ago it was at 90Hz.
I last reported on this in early June, where it was affecting the same channels, stage2 corner 2.
Noise not seen after power outage on June 6, maybe something needs a power cycle. FRS 5615 was closed after the bump went away.
Addendum--FRS 7565.
