UT 00:04 EFOSC2 skyflats UBVRi

UT 00:35 image analysis

UT 00:45 STDPHOT pg2336 UBVRi

UT 00:55 CSS121015:004244+132827 BVRi (good S/N)

UT 02:05 SSS120810:231802-560926 BVRi (Bband exposure time = 1x300s + 1x262s,

we changed the pointing after the first exposure because the SN was too close to a column of bad pixels.

The image quality is not high given the high airmass, however the SN is clearly detected in each band.)

UT 03:15 LSQ12hot gr13 *classification (IIn?)

UT 03:45 LSQ12dlf R (1st image is wrong field; then we got 3x300s. Unclear if the SN is there.)

UT 04:15 LSQ12hxg UBVRi (good S/N)

UT 04:40 LSQ12hxt gr13 *classification (Ia)

UT 05:15 STDPHOT RU152 UBVRi

UT 05:25 STDSPEC LTT3218 gr13 / slits 1.0"

UT 05:40 image analysis

UT 05:50 OGLE-2012-SN-051 gr13 *classification (Ia)

a few minutes lost to find the guiding star

UT 06:40 LSQ12hzo gr13 *classification (The spectrum looks like that of a galaxy. We did not see any clear point source

at the galaxy center)

UT 07:15 LSQ12hxn gr13 *classification (Ia)

UT 07:50 STDPHOT RU149 UBVRi

UT 08:05 STDSPEC LTT3864 gr13 / slits 1.0"

EFOSC2 bias, arcs and spectroscopic flat fields not taken in the morning because EFOSC2 had a technical problem
