Observations with EFOSC2. Cloudy night. Humidity between 67-74%

Tried the calibration data in the afternoon but EFOSC2 has had problems probably due to the mechanics of the instrument.
Clouds due to the locally famous Altiplano (aka Bolivian) winter.

UT 00:08   Opening the telescope. Too late for the skyflats.

UT 00:19   SPECSTD gd71         airmass=1.49    g11,13,16 sl 1.0

--DIMM SEEING is not working yet but we can see from the guide star that the seeing is bad, probably > 1.2". Humidity 67%.

UT 00:35   Focus made manually and the TO is having problems with the image analysis due to the bad weather conditions.

--SEEING ESTIMATION FROM FWHM OF CLOSER STARS ~ 1.7"--

UT 00:58   LSQ12hot             airmass=1.36    g13 sl 1.5

UT 03:02   Small technical problem of NTT 

--SEEING ESTIMATION FROM FWHM OF CLOSER STARS ~ 1.2"--

UT 03:15   SN2012hr             airmass=1.20    g11,16 sl 1.0

UT 04:24   SPECSTD L745a        airmass=1.06    g11,13,16 sl 1.5

--DIMM SEEING is back - 0.84"-- However, checking the acquisition image, we think that the seeing is larger than 0.84".

UT 04:36   SN2012hs             airmass=1.07    g16 sl 1.0

UT 05:59   SN2012ht             airmass=1.45    g11,16 sl 1.0

--DIMM SEEING 0.52"--

UT 06:47   SN2013K              airmass=2.08    g11,16 sl 1.0

--DIMM SEEING 0.75"--

UT 09:16   PSNJ15213475-072218  airmass=1.17    g13 sl 1.0      **Classification: possible type II. Noisy spectrum.

UT 09:55   END of the night.

Good night.
