Today morning we had some time after the earthquake to perform OPLEV charge measurements.
Results for ETMX are consistent with negative trend, now the charge is about 10 Volts on all the quadrants.
Results for ETMY do not not show a significant trend and below the 10 [V] Effective Bias Voltage.

Note. I'll check it again, but it seems that we had the wrong sign of applied bias voltage in charge measurements for ETMY. Applied bias was multiplied by -1 in filters.
Applied ETMY plots use the corrected sign for June 12 to July 14.
