MDM Trouble Report for 2019 Jun 22 Telescope: 2.4m Observer(s): Rupert, Jayasinghe (MDM, OSU) Instrument: OSMOS/B Problem(s) Encountered: At around 1:15 we slewed the telescope to near zenith to rotate the instrument. Once there, one of the screws of the RA drive preload snapped in half and flew out of its hole along with the washers. We've since recovered the half screw and all three washers. Decided to close up rather than risk further damage. Couldn't hear anything in the small movement to the telescope stow position... ------------------------------ Submitted on 2019 Jun 23 [2:09:21]
