SCIENCE OBSERVATIONS (SOFI)
Start at UT: 2345 - lots of cirrus cloud in the north, some elsewhere.
UT: 2345 - IR spec std - GD71 - in B and G gratings. (OB execution time 10m)
60s/120s exp - std looks very faint, especially in the red. will re do later
UT: 2355 - image analysis on mirror
UT: 0010 - LSQ12hxg (> 19mag) JHK (1h45m)
UT: 0100 - sky looks clear - cloud gone.
UT: 0145 - Telluric standard for PSNJ09 - Hip045705 (V = 7.96, I = 7.26) ( 5m )
UT: 0155 - PSNJ09491471-474456 BG (1h40m x 1.35)
Marshal requests just BG for this.
UT: 0430 cloud getting heavier

UT: 0445 - Spec Std SOFI LTT 3218 (10 * 1.35 = m)
UT: 0505 - PSNJ09491471-474456 JHK (35m * 1.35)
(no guiding as guide star not visible due to cloud)

Change to EFOSC2
UT: 0600 - arcs
UT: 0610 - PSNJ13540068-0755438 - gr13 (400s exp - due to cloud)
(cloud - but seeing good at ~0.7)
SNID: classified as a Ia at z=0.009 - epoch pre max.
UT: 0645 - CSS130303105205-133424 - gr13 (1500s exp - due to cloud)
SNID: classified as SN 1a 91T - 5-7d premax - z=0.07
Note: this target taken from the INBOX as no suitable high priority candidates in the classify queue.

UT: 0740 - Flux Std EFOSC EG274
UT: 0800 - SN2013K grism13 (35min)
Finder at SN2013K_FC.png - note that the coords of the SN refer to the centre of the host galaxy - not the SN
UT: 0845 - had to stop as too cloudy - no guide stars
UT: 0855 - arcs - PESSTO_calib_only_arcs
UT: 0910 - end of night - didn't look like cloud would clear.
