Observations with EFOSC2 the all night.


Seeing ~ 0.6" during the all night.

EFOSC2 biases + arcs / dome flats + spec.pol calib + skyflats grz

For spectro-polarisation, the centre of the central hole is (x,y) = (1034,987)

UT 00:47 HD-10038 spectro-polarisation test

Alignement problem. The star is at y=1054. No signal through the mask hole.

UT 01:10 SN2012dy gr16

UT 02:27 STD vma2 gr11 + gr13 + gr16 / slits 1.0" and 5.0" (S. Smartt)

UT 02:52 LSQ12gdj gr11 + gr16

UT 03:39 HD-13588 spectro-polarisation

With the TO and the advices from Stefan we finally understood

how to do it. The right template to use is MoveToPixel instead of

MoveToSlit to properly put the star in the mask hole.

UT 03:51 HD-42078 spectro-polarisation

UT 04:02 HD-10038 spectro-polarisation

UT 04:21 LSQ12gpw gr11 + gr16

UT 05:14 LSQ12hqs gr13 *classification*: no target

There is nothing at the target position (even on a V=80s exposure image)

UT 05:53 SQ12hnj gr11 + gr16

UT 06:36 LSQ12hng gr13 *classification*: idem, no target

UT 06:38 LSQ12hon gr13 *classification*: SN Ia z=0.18 around max (SNID)

UT 06:39 STD gd71 gr11 + gr13 + gr16 / slits 1.0" and 5.0"

+ 1 exposure slit 1.0" with no grism

UT 07:09 LSQ12hnr gr13 *classification*: SN Ia z=0.13 (0.005) age=-2.5d (SNID)

UT 07:26 LSQ12hml gr13 *classification*: cannot find the target;

finding chart with half of the field missing...

UT 07:36 LSQ12hns gr13 *classification*: AGN ???? or reduction problem ?

UT 07:58 LSQ12htu gr13 *classification*: SN IIb z=0.037 (SNID)

UT 08:29 STD LTT3864 gr11 + gr13 + gr16 / slits 1.0" and 5.0"

UT 08:51 HD-97689 spectro-polarisation

EFOSC2 skyflats grz

As a general remark, it could be more efficient if, for each detected

new transient, we wait for it to appear on at least two epochs

separated by at least one day (and not 3 minutes) before pushing the

target in the PESSTO marshall "classification queue". That way the NTT

observers will not waste the telescope allocated time looking for non

existent objects...
