EFOSC observations

- Because of wind we can't do the Spectroscopic standard star GD71

- 04:50UT: LSQ14gjn classification Airmass 1.29 Seeing 1.04". A bit cloudy and probably problem of galactic substraction. No determined.

- 08:10UT: L745a Spectroscopic standard star (gm11, gm13, gm16) Airmass 1.25 Seeing 0.9"

- 08:35UT: RU149 Photometric standard. Airmass 1.43 Seeing 1.00". Exposure aborted before its end.

- 08:42UT: electronic problem with EFOSC. Night aborted.

POST-OBSERVATIONS:

No post observations due to the electronic.
