----

CALIBRATIONS:

- 19:30UT - we have control of the telescope! No overhead clouds, but there are clouds on the horizon.

- 20:00UT - 2x PESSTO_bias & 1x PESSTO_calib

- 21:15UT - The telescope start-up begins

PRE-OBSERVATIONS:

- 23:20UT - Sunset

- 23:30UT - Skyflats: grz

- Conditions: Clouds on the horizon, but they might keep away. No wind.

- 23:50UT - SPECTROSCOPIC STANDARD: Feige 110: Seeing 0.9", Airmass 1.10

- 00:20UT - PHOT STD: TPHe (UBVRi): Seeing 1.1", Airmass 1.1

- 00:30UT - Focussing and image analysis

SCIENCE-OBSERVATIONS:

- 00:43UT - ASSASN-14kd: Classification for 300s: Seeing 1.0", Airmass 1.23

- 00:55UT - LSQ14fyc: Classification for 900s: Seeing 0.9", Airmass 1.04

- 01:15UT - SN2009ip: Follow-up in B (4x200s), V (3x200s), R (2x100s), i (2x200s): Seeing 0.9", Airmass 1.08 (+dark time).

- The SNe is still visible in the acquisition images even after 800 days!

- 02:00UT - SN2013hx: Deep follow-up in g, r, i: Seeing 0.75", Airmass 1.15

- The DIMM thinks the seeing is 0.6", but it's 0.75" from the images

- The SNe is not in the acquisition images (even after 1 minute exposures), but these are deep images, so fingers crossed!

- The seeing stays constant through the observations 0.7" at the end.

- 03:20UT - ASASSN-14il: Follow-up in BVri & gm11 for 900s & gm16 and 900s: Seeing 0.8", Airmass 1.1

- 04:15UT - LSQ14gae: Classification for 900s: Seeing 0.9", Airmass 1.55

- 05:00UT - SPECTROSCOPIC STANDARD: L745a: Seeing 0.9", Airmass 1.74 (this is a terrible time to be doing STDs!)

- 05:20UT - PHOT STD: TPHe (UBVRi): Seeing 0.7", Airmass 1.42

- 05:30UT - OGLE-2014-SN-073: BVRi + gm13 for 2x3000s: Seeing 0.8", Airmass 1.22 at start, Seeing 0.5", Airmass 1.2 in the middle

- 08:00UT - OGLE-2014-SN-125: Classification for 600s: Seeing 0.6", Airmass 1.4

POST-OBSERVATIONS:

- 08:20UT - PHOT STD: RU149: Seeing 0.6", Airmass 1.14

- 08:40UT - STANDARD: L745a: Seeing 0.6", Airmass 1.02

- 09:00UT - Skyflats: BR

CERRADO POR EL NOCHE!

SCIENCE-CONCLUSIONS:

- ASSASN-14kd: CLASSIFICATION: SN Ia-91T @ z=0.027 @ -10days (SNID)

- LSQ14fyc: CLASSIFICATION: SN Ia @ z=0.082 @ +10days (SNID)

- ASASSN-14il: FOLLOW-UP: Lots of galaxy light in this one. SNID has issues, but super fit likes it to be a SN II @ z=0.02 @ +9.

- LSQ14gae: CLASSIFICATION: SN IIP @ z=0.041 @ +6 days

- OGLE-2014-SN-073: FOLLOW-UP: SN IIP @ z=0.127 @ +10 days

- OGLE-2014-SN-125: CLASSIFICATION: SN IIP @ z=0.023 @ +20 days
