2010-12-01 (UT) =============== Program: CL2 (YSOs, PI: Baron 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 many clouds *** S2E1W2, W2=ref. LT 17:45 - HD15464 (fringe finding star) E1 is oscillating like crazy this time along azimuthal axis, yesterday we adjusted elevation Laszlo goes out to fix it so we are switching configuration *** S2E2W2, W2=B2=ref. LT 18:10 - HD177724 (fringe finding star) B1B2=-0.246 cm (S1), B2B3=+1.02 cm (E2) LT 18:48 - HD180684 (calibrator for MWC614) find cross-fringe, but cannot find individual fringes (later we find that the HD number in configure was not updated, so this might explain why we could not find individual fringes) W2 dome does not move automatically and has to be recenter everytime manually LT 19:20 - HD194093 (alignment star for MWC340) B1B2=-0.188 cm (S1), B2B3=+0.961 cm (E2) LT 19:40 - 197488 (calibrator for MWC340) B1B2=-0.188 cm (S1), B2B3=+0.961 cm (E2) problem with S2 (past throught target while slewing) problem with delay lines LT 20:00 - when closing S2, the telescope continues to move after restarting, it stops, but the SPY1-camera does not show an image PJ is worried about the safety of the telescope *** S1E1W1, W1=B2=ref. LT 20:10 - when starting up E1, there is a problem with synching the clock LT 20:30 - when going to the star, there are EXTREMELY strong oscillations (0-loops and 8-loops) on S1 oscillation appear in different regions Larry says that the S1 also make fog horn noise and had to be turned off LT 21:10 - changing POPs to replace S1 with S2 POP S2 to 4 (S1S2E1E2W1W2: 4-4-4-1-2-5) *** S2E1W1, W1=B2=ref. LT 21:40 - HD27382 (fringe finder star) could not find fringes LT 22:00 - HD27848 (calibrator for RY Tau) delay line goes to the wrong position system does not take new targets oscillation or something similar in S2, since the star slowly drifts out in tiptilt (green dots move out) whenever we change star, we have to manually set the HD number again CLIMB crashes all the time could not find fringes LT 22:55 - HD43386 (calibrator for MWC147) could not find fringes LT 23:20 - HD53510 (doing NIRO alignment again) B1B2=-0.431 cm, B2B3=+??? (cannot find B2B3 fringe) reboot IRIMAGE computer in order to hopefully fix NIRO crash problem LT 23:30 - HD43386 (calibrator for MWC147) B1B2=-0.431 cm, B2B3=+0.536 cm LT 23:45 - HD47157 NIRO crashed again (9th time this night) B1B2=-0.431 cm, B2B3=+0.536 cm recording data (NON-DEST, 750 Hz, LONG), good quality, but low number of frames B1B2=-0.439 cm, B2B3=+0.553 cm LT 00:00 - MWC147 running out of delay *** S2E2W2, W2=B2=ref. LT 00:10 - HD43386, seeing 3-7 cm doing NIRO alignment B1B2=-0.1637, cm, B2B3=+0.766 cm LT 00:30 - HD47157 (calibrator for MWC147) B1B2=-0.196, cm, B2B3=+0.729 cm recording data (NON-DEST, 750 Hz, LONG), good quality B1B2=-0.195, cm, B2B3=+0.729 cm LT 00:40 - MWC147 B1B2=-0.191, cm, B2B3=+0.740 cm recording data (NON-DEST, 750 Hz, LONG), good quality, all baselines very clear B1B2=-0.191, cm, B2B3=+0.740 cm LT 00:55 - HD47157 (calibrator for MWC147) have to recenter W2 dome have to reinitiate telescope position on nearby bright star recording data (NON-DEST, 750 Hz, LONG), good quality B1B2=-0.195, cm, B2B3=+0.754 cm LT 01:20 - MWC147 B1B2=-0.192, cm, B2B3=+0.767 cm recording data (NON-DEST, 750 Hz, LONG), good quality LT 01:35 - HD47157 (calibrator for MWC147) B1B2=-0.194, cm, B2B3=+0.775 cm recording data (NON-DEST, 750 Hz, LONG), good quality LT 01:45 - HD52456 (alternative calibrator for MWC147) recording data (NON-DEST, 750 Hz, LONG), good quality B1B2=-0.190, cm, B2B3=+0.764 cm LT 01:56 - MWC147 recording data (NON-DEST, 750 Hz, LONG), fringe much fainter than before (seeing has not changed) B1B2=-0.184, cm, B2B3=+0.800 cm (found out later: maybe the lower SNR was due to occultation by the W2 dome?) LT 02:10 - HD52456 (alternative calibrator for MWC147) recording data (NON-DEST, 750 Hz, LONG), good quality B1B2=-0.186, cm, B2B3=+0.792 cm LT 02:35 - HD41547 (bright star for alignment) S2 tip tilt does not lock on this very bright star, searching for solution LT 03:00 - HD34745 (calibrator for MWC120) B1B2=-0.186, cm, B2B3=+0.792 cm NIRO crashed again giving up, since it will get too late for the science star LT 03:15 - HD56405 (calibrator for MWC166) cannot find fringes, strange LT 03:30 - HD55137 (calibrator for MWC166), seeing 2-8 cm B1B2=-0.184, cm, B2B3=+0.800 cm LT 03:50 - HD52938 (bright star for new NIRO alignment) NIRO alignment, searching fringes finding fringes, very poor quality despite high flux and high contrast B1B2=-0.180, cm, B2B3=+0.??? cm LT 03:30 - HD55137 (calibrator for MWC166) still no fringes... homing carts, etc. LT 04:55 - HD73262 (calibrator for Beta CMi) found fringe on B1B2 baseline at expected position other fringe still does not show up LT 05:15 - closing down (PJ insists on closing at 5:15)
