Closed for 5 hours because of wind. Observed cart 3 plate 3319 and cart 5 plate 3308. Obtained some signal. We had the same problem with guider as several days ago (see MJD 54910 log) We tried to do focus loop several times during the night but it never finished. After some measurements, it stoped with a error message: expected guider frame never arrive. We had to manually adjust the focus. ---=== OBSERVING LOG ===--- Afternoon: ---------- Cart 1, plate 3359 Marvels FF test until 00:45Z Cart 3, plate 3319 mounted telescope is checked and all systems are in good working condition. 01:09 postCalibs collimate Spectro set for 9C and did not adjust. Night: ------ Some clouds but they were going away. 01:20Z ventilation 01:30Z enclosure is off Cart 3, plate 3319, segue No previous observations. 01:59 gotoField Used FK5 We tried focusLoop twice but it stopped as "expected new guider image did not arrive". The third try was good.
