Photometric night - clouds on the horizon and seeing ~1.0".
12 Nov: EFOSC2 night - focussing on spectroscopy. Full details can be found here: https://docs.google.com/document/d/1yz5Jf_IHjd254sVu43XVsEjQ8WAnBu8pSSfesGyaPt8
- 19:30UT - we have control of the telescope! The weather looks fairly reasonable - no overhead clouds
- NOTE that ROSETTA successfully landed on a comet this afternoon!
- 20:00UT - 2x PESSTO_bias & 1x PESSTO_calib
- We have checked and the slit is located at Y=991 (for the 1" slit).
- We've also checked and the slits and grisms are properly aligned
- 21:15UT - The telescope start-up begins
- 23:20UT - Sunset
- 23:25UT - Skyflats UVi (BR is attempted but aborted - stars in the image)
- 00:10UT - STANDARD: Feige 110: Seeing 0.9", Airmass 1.1. The weather looks good
- 00:30UT - Focussing and image analysis
- 01:00UT - ASASSN-14jb: gm11 for 1500s: Seeing 1.1" (from image) Airmass: 1.04
- 01:30UT - LSQ14fxj: gm11 for 2x2700s & gm16 for 2x2700s - 3hours total: Seeing 0.9" Airmass 1.45 (and rising)
- Due to an oversight, gm16 is done without a OB filter and the flats for gm16 are done in a separate OB (also without an OB filter).
- There is a clear trace in the gm11 spectra and it's also in gm16 (albeit fainter).
- 05:00UT - LSQ14gcs: gm13 for 1500s: Seeing 0.9" Airmass 1.25
- 05:45UT - LSQ14gcj: gm13 for 900s: Seeing 0.8" Airmass 1.10
- 06:00UT - LSQ14gci: gm13 for 900s: Seeing 0.8" Airmass 1.11
- 06:30UT - STANDARD: L745a (including a slit=1.0, gr16+no filter for use with LSQfxj): Seeing 0.8" Airmass 1.15
- 07:00UT - ASASSN-14ha: gm11 for 1800s & gm16 for 1200s: Seeing 1.0" Airmass 1.16
- 08:05UT - LSQ14gch: gm13 for 1500s: Seeing 0.7: Airmass 1.3
- 08:45UT - STANDARD: L745a (including a slit=1.0, gr16+no filter for use with LSQfxj): Seeing 0.8" Airmass 1.15
- 09:10UT - Skyflats in B&R
END OF THE NIGHT

ATEL SUBMITTED FOR LSQ14gcs, LSQ14gcj, LSQ14gci, LSQ14gch (http://www.astronomerstelegram.org/?read=6695)
MESSAGE FROM STEPHEN - KEPT FOR LATER IN THE RUN:Note to observers - when conditions allow, do the imaging for SN2013hx with the OB below. This dithers between frames, and we want to test the fringe removal in i-band in particular with deep imaging.
