HIP End Water **PICS PROBLEM**: Wed Mar 3 18:46:20 GMT 1999 The disk image looks overexposed at the current exposure setting of 3.

For some reason the exposures are still 25 and 3, so I changed them to 10 and 2 in the ProgramDefs script which can be found in /local/usr/local/src/ACOS/Bin directory. **PICS PROBLEM**: Wed Mar 3 19:15:00 GMT 1999 The disk images now look great, the focus looks better than I've ever seen it. The display gain is set to 4 to see the best image quality, but that causes the limb images to be overexposed, so I am trying different limb exposure settings to find the setting that works the best with the display gain of 4. **** EVENT COMMENT ****: Wed Mar 3 19:40:41 GMT 1999 A faint CME has been in progress since about 1841 ut at PA=250, there is a nice small EPL at that location also. CHIP COMMENT: Wed Mar 3 19:58:15 GMT 1999 The EPL at PA=250 is visible in the images as continuum scaled pixels at the front of the EPL, indicating a doppler shift away from us.

I waited for a full 6 minutes hoping that it would clear by the next cycle where the barrel is at the same place and going in the same direction as the software might see it (although in reality it just sat there for those 6 minutes and wasn't really turning according to the Barrel Angle LED readout on the OCP panel. That worked, the problem cleared itself, it is scanning normally again.

PICS COMMENT: Wed Mar 3 21:08:27 GMT 1999 The camera needs to be centered in th X direction, I will hold off on doing that until after the CME is finished because I'll be bumping the Spar around while I adjust the camera. The optimum exposure times appear to be 3 msec for the limb images and 5 msec for the disk images. The Display Gain should be set to 2 when adjusting the exposure, to get the most accurate view displayed in the Display window of what the actually sees. During normal observations the Display Gain also works well when set to 2.

But I didn't make it, the first quadrant of the first cal scan was affected by having the dome shutter blocking the sun. So I will do another cal after this cal, the 2nd cal is the good one. PICS COMMENT: Wed Mar 3 22:39:11 GMT 1999 I'll try to do the camera adjustment tomorrow, not enough time left today.

Sure would be nice if we had our own email server up here. **MLSO PROBLEM**: Wed Mar 3 23:54:56 GMT 1999 I was able to login to Boulder using the modem and RAS account.
