Huehnerhoff Opened at sunset after the local weather cleared. Weather continued to clear for first program and stayed relatively clear the remainder of the night. Seeing was also good. Around 2145MT I noticed some odd behavior on the strip chart. There was more noise than usual on the az current display while guiding in the NE (az/alt 147.5/76.6). I could not hear anything over the intercom but thought the behavior was a little odd. This noise was not visible when tracking in the NW.
