I think the program cannot find the limb due to all of the thick clouds. CHIP COMMENT: Thu Jul 25 16:45:44 GMT 1996 Now m2 is running itself to a limit.

I think the cirrus is finally thin enough for the CHIP to find the limb and stay centered.

First camera images after limb > disc > limb > k-corona change catches wheel still in transition. Stopping and restarting Patrol to see if that helps.

Performed GONG maintenance while down the hill. CHIP O1 ran away again in heavy clouds. COMMENT: Thu Jul 25 18:43:32 GMT 1996 Reconfigured dome shutter during heavy clouds. CHIP COMMENT: Thu Jul 25 18:56:35 GMT 1996 Developed a attention and labor intensive technique to use during heavy clouds. Watch the mic controller like a hawk. As soon as tape writes occur, the M1 will begin running away in the negative direction. Quickly press rem/local then M2. This stops the M1 movement. If this is done quickly, you won't have to jog the M1 so far and use too much time doing it. Next press M1 and jog it back into position. Then press rem/loc again to switch back to remote. Normally, one would not be observing at all in clouds this thick.
