While investigating what is reported in entries 14381 and 14401 I realized the BS IP actuation showed a similar behavior to SR2. See the picture:

• IP H1 actuation began increasing on the 5th of May at 21:35 UTC in a similar way as SR2 on the 7th of May UTC.
• SRM and SR3 didn't show a similar behavior in the interval of time examined.
• Just as a reminder, as pointed in one of the entries cited above, the SR2 event doesn't seem to be produced by an earthquake.

Fortunately the BS IP coil driver is still functional. More investigation is needed.
