Night Report 2015-01-19

Observers: Christoffer Fremling, Anders Nyholm

TAT: Nancy Elias-Rosa, Lluís Galbany

Conditions OK, no clouds at the start of the night. Tonight we start with SOFI spectroscopy and photometry, and later switch to EFOSC spectroscopy for classifications with the majority of the night dedicated to follow-up.
