MDM Trouble Report for 2024 May 30 Telescope: 1.3m Observer(s): Huiyang, Mao (PMO) Instrument: CCDS Problem(s) Encountered: When I wanted to open the fits from the folder data in the ds9, the application was stuck. Then I used terminal on my computer to visit obs13m@140.252.83.61 and entered the folder data, it was stuck too, and nothing shown on the screen, then I sent the first email. After you replied to me, I can visit the folder \data but the ds9 was still stuck and I could not open other applications after I tried to open another ds9. Other things went like before. At about 21:30, when I tried to download the first observation data from the server, I met the problem I described in the email. Before that, I used the rsync to upload the calibration files to Jiangtao‘s server, and everything went well. ------------------------------ Submitted on 2024 May 31 [4:06:03]
