0830:	MCC adjusted pathlength

0830:	The rear x1 histogram has a ragged region of about 16 channels.

1000:	Rear x1 histogram is getting worse.  Bad region about 32 channels

1045:	Most FPP spectra are now bad and reconstruction is affected.

	We've called Mark Jones about FPP and plant engineering

	about the temperature in the hadron hut.  They report that the

	temperature reading is still about 78 deg, but perhaps it is

	worse near the electronics.  

1100:	arranged for access at about 1130 with Mark and engineering

1100:	CHL alarm takes all RF off.  MCC evaluating problem and

	recovery time.

1145:	enter Hall to check FPP multiplexing and hut air conditioning

1315:	leave hall.  Air conditioner on rhs was off.  Plant engineering

	changed filter and restarted unit.  No obvious problem with

	signals, but timing shifts could be subtle.  Running cosmics

	while hut cools down again.
