MDM Trouble Report for 2014 May 25 Telescope: 1.3m Observer(s): De Rosa/Stevens (OSU) Instrument: CCDS Problem(s) Encountered: N-S nodding: We detected small amplitude NS nodding while observing the first standard star feige34 (RA 10 39 36 DEC +43 06 09 secz=1.11-1.13). Large amplitude N-S nodding was instead detected while observing ngc 3227 (RA=10 23 30.57 DEC=+19 51 54 secz=1.25-1.40). The oscillations made guiding impossible, causing the source to move out of slit. Guiding issues: The guiding was lost twice, suddenly, and without apparent explanation while observing two different objects. Targets were moved out of slit as a result of a large shift (~1''). ------------------------------ Submitted on 2014 May 26 [4:43:39]
