2010-12-03 (UT) =============== Program: CL2 (YSOs, PI: Kraus et al.) Observers: Stefan Kraus, PJ Goldfinger B1 B2 B3 ---------- S1 W1 E1 S2 W2 E2 (S1S2E1E2W1W2: 4-1-4-1-2-5) CLIMB on beam 1,2,3 *** S2E1W2, W2=ref. LT 17:20 - HD24365 (NIRO alignment star) LT 17:40 - HD3590 (fringe finding star) B1B2=-0.186 cm, B2B3=+0.800 cm still out of delay for all YSO LT 18:00 - HD103481 (calibrator for 37 And), seeing 2-10 cm B1B2=-0.187 cm, B2B3=+0.791 cm recording data (750 Hz, DEST, LONG) LT 18:15 - HD5448 (=37 And) B1B2=-0.179 cm, B2B3=+0.818 cm recording data (750 Hz, DEST, LONG) LT 18:28 - HD10348 (calibrator for 37 And) B1B2=-0.187 cm, B2B3=+0.791 cm recording data (750 Hz, DEST, LONG) LT 18:55 - HD5448 (=37 And) recording data (750 Hz, DEST, LONG) LT 19:08 - HD10348 (calibrator for 37 And), seeing 4-10 recording data (750 Hz, DEST, LONG, 5 Samples/Fringe = default value!) ------ LT 19:16 - HD24365 recording data (1000 Hz, DEST, LONG, 4 Samples/Fringe!) Based on recommendation from Theo we changed the "Samp/Frg" value from 5 (default) to 4!!!! B1B2=-0.196 cm, B2B3=+0.804 cm LT 19:30 - RY Tau too many clouds, can find star only in 2 telescopes LT 20:00 - HD24365 (early calib for AB Aur) B1B2=-0.187 cm, B2B3=+0.792 cm LT 20:05 - AB Aur B1B2=-0.187 cm, B2B3=+0.792 cm still out of delay since E1 goes only to 42m LT 20:08 - HD30111 (early calib for AB Aur) recording data (1000 Hz, DEST, LONG) B1B2=-0.196 cm, B2B3=+0.808 cm piston is quite strong, seeing 1-8 cm LT 20:17 - AB Aur cross fringe: B1B2=-0.1918 cm, B2B3=+0.8067 cm recording data (1000 Hz, DEST, LONG, 4 Samples/Fringe) the cross fringe was very clear, but maybe the other ones were also there sometimes we go to 2000 Hz, NON-DEST, 1/2 Aperture mask to avoid saturation, much better than with NON-DEST ! cross fringe: B1B2=-0.2184 cm, B2B3=+0.8086 cm recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL) B1B2=-0.1964 cm, B2B3=+0.8273 cm lost E1 in the middle of data recording, re-acquired successful nice data LT 20:52 - HD30111 recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL) recording data (1000 Hz, DEST, LONG, 4 Samples/Fringe, 1/2 Aperture wheel) Aperture wheel was still in ! 20-30 counts B1B2=-0.195 cm, B2B3=+0.823 cm LT 21:05 - AB Aur recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL) B1B2=-0.193 cm, B2B3=+0.822 cm LT 20:52 - HD30111 recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL), 40-50 counts B1B2=-0.195 cm, B2B3=+0.824 cm LT 21:05 - AB Aur recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL) B2B3 fringe is not as clear as before, but still there B1B2=-0.196 cm, B2B3=+0.824 cm still clouds, but tracking in OK, seeing 2-7 cm LT 21:35 - HD29859 (alternative calibrator for AB Aur) recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL) LT 21:41 - HD30111 (primary calibrator for AB Aur again) recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL) B1B2=-0.195 cm, B2B3=+0.824 cm LT 21:45 - HD41547 (calibrator for MWC120) LT 21:52 - HD34745 (calibrator for MWC120) recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/2 APWHEEL), interrupting and recording without aperture wheel problem with delay lines (situation again where delay is good only for a few minutes before reset is required) LT 22:00 - HD32480 (calibrator for SU Aur) recording data (1000 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) B1B2=-0.187 cm, B2B3=+0.8364 cm LT 22:15 - SU Aur clouds get worse During acquisition I made sure that this is not AB Aur (i.e. not the brightest source in the field) recording data (1000 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) B1B2=-0.187 cm, B2B3=+0.8584 cm fringe on B2B3 (=W2E1) quite clear, B3B1 is sometimes maybe also there LT 22:30 - HD32480 (calibrator for SU Aur) recording data (1000 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) B1B2=-0.187 cm, B2B3=+0.8584 cm LT 22:40 - HD53510 doing NIRO alignment LT 22:40 - FU Ori cannot acquire, clouds seem to be very bad LT 22:54 - HD47157 B1B2=-0.21 cm, B2B3=+0.84 cm recording data (750 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) fringes jump really bad on this calibrator (seeing 2-8 cm, but piston seems to be bad!) only 5 counts, we won't be able to find fringes on MWC147 with these conditions LT 23:10 - changing configuration to be ready later LT 23:20 - we are idle due to clouds *** S1E2W1, W1=B2=ref. LT 01:15 - it seems to clear up a bit LT 01:15 - HD53510 (bright alignment star) doing NIRO alignment LT 01:33 - HD38164 (calibrator for FU Ori) W1 and E2 are initialized on the wrong star, so we paddle around to find the proper star cannot find star with paddling going out to W1 and E2 dome to reinit telescopes on Betelgeuse after coming back, it still does not go to right star after resynching the telescope time it works LT 02:43 - HD56405 (calibrator for HD58647) E2 is oscillating quite badly cannot find fringes LT 03:15 - changing configuration *** S2E2W2, W2=B2=ref. LT 03:22 - HD53510 doing NIRO alignment LT 03:40 - HD50277 B1B2=-0.154, cm, B2B3=+0.915 cm recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) LT 03:45 - FU Ori cannot acquire star LT 03:50 - HD50277 (calibrator for MWC147) B1B2=-0.154, cm, B2B3=+0.915 cm recording data (1000 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) B1B2=-0.149, cm, B2B3=+0.926 cm LT 04:00 - MWC147 cannot acquire star LT 04:05 - HD56405 cannot acquire star LT 04:10 - HD73262 (calibrator for Beta CMi) B1B2=-0.169, cm, B2B3=+0.856 cm recording data (1000 Hz, NON-DEST, LONG, 4 Samples/Fringe, NO APWHEEL) flux increases during integration, likely due to changes in the clouds, so we might saturate on the target so I repeat with 1/4 APWHEEL recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 04:25 - Beta CMi B1B2=-0.153, cm, B2B3=+0.918 cm Recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 04:33 - HD73262 recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 04:45 - Beta CMi B1B2=-0.153, cm, B2B3=+0.918 cm recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 04:50 - HD73262 recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 04:59 - Beta CMi recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 05:05 - HD73262 recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 05:10 - Beta CMi recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) LT 05:15 - HD73262 recording data (2000 Hz, NON-DEST, LONG, 4 Samples/Fringe, 1/4 APWHEEL) maybe no fringe due to low counts... clouds? LT 05:18 - closing down
