Night Report 2014-11-24

Observers: Mathew Smith, Rob Firth & Georgios Dimitriadis

TAT: Joe Anderson, Nancy Elias-Rosa

Non-photometric night: We start with overhead clouds and are closed for several hours. There are then high winds to finish the night!

24 Nov: EFOSC spectroscopy. Full details can be found here:https://docs.google.com/document/d/1FWz22eV1aq7ZrZNTtZ0Ym3EUKpnzTZtpUltbsCsPUOI

CALIBRATIONS:

- 19:30UT - we have control of the telescope! There are overhead clouds though. It's not clear we will open with this.

- 19:30UT - 2x PESSTO_bias & 1x PESSTO_calib

PRE-OBSERVATIONS:

- 23:30UT - Sunset: Amazing.

- Conditions: Overhead numerous clouds (especially to the south) but we're open. No sky flats

SCIENCE-OBSERVATIONS:

- 00:10UT - ASASSN-14jz: Classification with gm13 for 300s. Seeing 1.0", Airmass 2.0 (this is setting fast, so we do it before twilight!)

- Observed twice as the sun is still up!

- 00:20UT - Telescope focus and alignment check

- 00:30UT - SPECTROSCOPIC STANDARD: Feige 110. Seeing 0.8", Airmass 1.12

- 01:00UT - TELESCOPE CLOSED DUE TO CLOUD COVER

- 05:00UT - STILL CLOSED (ALTHOUGH I CAN SEE STARS)

- 06:00UT - WE OPEN

- 06:15UT - PESSTOESO145-G10: Follow-up with gm11 for 2x1800s. Seeing 1.0", Airmass 1.33

- 07:20UT - LSQ14gfc: Classification with gm13 for 1500s. Seeing 1.2", Airmass 1.42. The wind is now "moderate"

- 08:00UT - LSQ14gfb: Classification with gm13 for 900s. Seeing 1.1", Airmass 1.14.

- 08:20UT - ASASSN-14ko: Classification with gm13 for 450s. Seeing 0.9", Airmass 1.20. The wind is now "high"….

POST-OBSERVATIONS:

- 08:35UT - SPECTROSCOPIC STANDARD: L745a: Seeing 0.9", Airmass 1.02

- 08:55UT - PESSTO_calib (arcs only)

- 09:00UT - DONE FOR THE RUN

CERRADO POR EL NOCHE!

SCIENCE-CONCLUSIONS:

- ASASSN-14jz: (Classification) SN Ia @ z=0.012 @ +3days (SNID) - both spectra are identical.

- PESSTOESO145-G10: (Follow-up) SN Ia-91T @ z=0.015 @ -5 days (SNID)

- LSQ14gfc: (Classification) SN Ia @ z=0.125 @ -2 days (SNID)

- LSQ14gfb: (Classification) SN Ia @ z=0.050 @ +3 days (SNID)

- ASASSN-14ko: (Classification) SN IIn @ z=0.042 (Mark) - this looks like a galaxy to me!
