### OBSDATE ### 20130411 ### LOGDATE ### 130411 ### OBSERVERS ### ACR ### WEATHER ### Ok, definitely poor seeing. Then cloud ### LOCATION ### MQ ### PROGRAM ### Sco-Cen Orbit monitoring ### SIDEROSTATS ### n4 s3 ### TARGETS ### Bet-Cru (fringe finding), 6:20pm. Very quick acquisition. Pointing offsets, North: -16, -21 South: -20, -156 Fringes at 600um. Gain set to 230 Ksi02-Cen (hr 4942) V=4.3: Fringes at 520um patchy, probably due to high airmass. Confirmed shutters moving. f-Cen (hr 4940) V=4.7: Can't find fringes in -200-700um. Should be around 300um based on past information. Note, have never found fringes on this star at high airmass. Is it just too faint? Trying Ksi02-Cen again to check I can get fringes: Found at 470um, but N4 failed and needed power cycling half-way though integration. Fringes are very intermittent. (Fringes at 430um after N4 fail) f-Cen: Tried again, but still no fringes. Iot-Lup (hr 5354) V=3.6: A bright calibration for Tau01-Lup. Fringes at 560um. Tau01-Lup (hr 5395) V=4.5: Fringes at 450 um after much careful searching. Iot-Lup: Fringes at 470um. Tau01-Lup: Fringes at 410um very patchy Iot-Lup: Fringes at 430um. Going back to f-Cen block as it's fairly high now (9:30pm). Ksi02-Cen (hr 4942): Fringes at 310um. Better than previous objects f-Cen (hr 4940): Thin cloud has arrived, and rain to the north, consistent with the massive cloud on it's way from QL. Closing. ### QUALITY ### Quite bad (no/almost no useful data ### PROBLEMS ### I have found that while the pellicle is moving, I am clicking the north or south servos on. Maybe the timing of when taskmaster turns them back on should be shortened.
