Today the fluid level in the HEPI system was down by 7/16" since I last looked on 10 May.  That is the day Jim and I did the accumulator charge check.  I checked the runs and could find no trace of fluid outside the system.  None in the relief or overfill lines at the reservoir.  I suspect that one or more of the accumulators that were checked on the 10th started leaking when we left them.

I'd like to check the charge again asap, certainly before going back to full IFO ops.  This requires the SEI to be completely off-line so the HEPI Pump can be stopped.  Look for a WP 6655.
