SN 2013fq g11+g16 00:40 A

LSQ13cuw g13 01:50 ? faint (clouds?), not sure what this is, blue continuum

PS1-13eao g13 02:20 B seemingly young Ia, -12d, z=0.033, reddish continuum

PSN015914+1901 VRi 02:55

SN 2013ej g11+g16 03:50 A seeing ~1"

LSQ13dbj g13 05:17 B looks like broad Balmer lines in emission at z~0.06 (seeing ~0.9")

LSQ13dbn g13 06:09 C seriously cloudy, looks like normal Ia at z~0.1

LSQ13dbn g13 06:41 C try it again. Even fainter than first attempt

LSQ13dbx g13 07:20 B looks like Ia at z~0.08, near max

Several objects tried but looked too faint on acquisition images. A fair amount of time spent trying to observe "between" the clouds. This resulted in quite high airmass observations for some objects (better that than no photons at all).

Calibrations morning: EFOSC bias; EFOSC dome spec flats + arcs
