night-report-page-20131123 Observers: Michel Dennefeld, David Bersier TO: Pablo Support team: Stephen Smartt, Ken Smith TAT on duty: Richard Scalzo, Cosimo Inserrra ------------------------------------------------ Instruments: EFOSC2 WEATHER CONDITION beginning: wind speed 3 m/s, humidity 35%, fairly cloudy middle: wind speed 5 m/s, humidity 20%, cloudy, poor conditions end: wind speed 9 m/s, humidity 24 %, cloudy afternoon CALIBRATIONS: EFOSC2 Spectroscopic arcs OBSERVATIONS: start regularly at sunset. All night with EFOSC2, spec with slit 1" Object Filters/grism UTstart Grade comment 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 |
