Subject: last night's time series. 
Hi all,

here are some new time series taken last night. The usual data with
IC in B and C disconnected so disregard these curves. The diode sum
is quite stable in att. 1. Att. 2 shows the beam position.
A significant vertical beam motion of 130 microns is noted.
We will likely need to implement vertical feedback for the beam time.
Dohn Arms is working on it. I was told by former COM-CAT staffers
that they never used feedback on 32ID.
