MDM Trouble Report for 2000 Dec 25 Telescope: 1.3m Observer(s): Soo-Chang Rey & Eon-Chang Sung (CSA, Yonsei Univ & KAO) Instrument: CCD Direct, Echelle Problem(s) Encountered: After the 04h (LT), TV guider didn't guide a star in the EW direction. Though we have made a few trying of rebooting the PC and telescope system, it was failed to solve the problem. While the wind was more or less strong (5-10 m/h) in the NW direction, guiding problem could not be related with wind direction, when we tested in a few direction of telescope. ------------------------------ Submitted on 2000 Dec 25 [6:30:30]
