LBT OSURC Partner Observing Notes
February 21, 2015 (Night 6)
Observers: Sarah Jane Schmidt, Scott Adams, Jake Turner
Support Astronomer: Barry Rothberg (on call)
Telescope Operator: Geno Bechetti


Summary:
Did not open as scheduled due to a thick cloud cover. At UT ~7:00, dewpoint rose to within 2 degrees of the temperature. By UT 10:40, clouds cleared and humidity dropped so we opened the telescope. We were able to obtain some data on two objects and a telluric standard through patchy clouds and poor seeing. We did not mark as done in the queue because we were unsure sufficient signal was obtained. 


Targets observed:
OSU_SDSSRMnirqso/srmJ141039
OSU_SDSSRMnirqso/HIP71172 (telluric standard for srmJ141039)
OSU_SDSSRMnirqso/srmJ141007




UT 2:00 overcast


UT 3:58 test dark on LUCI, seems fine


UT 7:00 humidity spike


UT 10:33 humidity down, clouds clearing, opening dome
        somewhat high winds - 5-15 m/s
        2” seeing


UT 11:06 slewing to OSU_SDSSRMnirqso/srmJ141039
UT 11:33 starting science exposure for OSU_SDSSRMnirqso/srmJ141039
        seeing varying from 1-2”, thin cirrus, winds 5-15 m/s
        first exposure, sky lines at brightest are at 15000 (well under saturation)
UT 11:55 running script again due to low flux in target and variable conditions
        at UT ~12, hit a 2 magnitude cloud


UT 12:17 slewing to OSU_SDSSRMnirqso/HIP71172
failed to find guide star, Geno checking pointing - probably failed due to pointing
UT 12:22 slewing to OSU_SDSSRMnirqso/HIP71172
UT 12:32 taking spectra for OSU_SDSSRMnirqso/HIP71172
Camera wheel error first try, pressed initialize, cleared error
UT 12:33 problem resolved, taking exposures now


UT 12:38 slewing to OSU_SDSSRMnirqso/srmJ141007
UT 12:54 starting science observations for OSU_SDSSRMnirqso/srmJ141007
        seeing from 1-2”, very light clouds
        this one may have sufficient flux, but we did not mark done because conditions were subpar and we did not have time for a second set of exposures.

UT 13:20 morning twilight - closing
