Alerting Randy to problem. While watching images inside main optics box, I observed that the image on the guider lens was not centered, with part of the image spilling off the glass. At 1739, the image suddenly centered itself. Looked at GUI image and the image was finally well centered. Something in the guiding system may be intermittent. **PSPT PROBLEM**: Fri Jul 13 17:55:37 GMT 2001 PSPT guiding appears stable now. **MKIV PROBLEM**: Fri Jul 13 17:57:54 GMT 2001 Very strange 1703 image on hoike. Image is circularly streaked with Moire-like patterns at 0, 90, 180, and 270 degrees.

The guiding problem appeared to be the ephemeris program overriding the quad cell's attempt to make corrections to the RA and DEC and keep the image centered. This appeared to be the case when I manually pointed the spar so that the image fell approximately centered on the guider lens and then the spar would offpoint suddenly before taking images. The only hardware problem I observed was the lazy response to tracking in the early morning during my attempts to manually point the spar. This could be a gain problem compounded by the sun's attenuation by the atmosphere very early in the morning. COMMENT: Fri Jul 13 19:20:56 GMT 2001 Reconfigured dome shutter. WEATHER COMMENT: Fri Jul 13 19:50:53 GMT 2001 In scattered orographic clouds. PSPT COMMENT: Fri Jul 13 19:51:15 GMT 2001 Stopping PSPT to prevent it form cloud-chasing and screwing up the ephemeris.
