Subject: using OSEMs to look at seismic activity 

Rana suggested using OSEM sensing voltages as guide lines to look seismic activity.

As you see todays drilling and tumping activity was nothing compared to the EQ of mag 5 and 4

Optic level servos are turned back on.

 

What Steve means is that there is some drilling going on in the CES shop to accomodate the new water flume group. We want to

make sure that the mirrors don't move enough to break the magnets. On the dataviewer we should look to make sure that the

sensor channels stay between 0-2 V.     -Rana
