We continue to receive reports of a few observers who are
having problems using Xremote. We believe the biggest problem is that the
observer is starting their ssh session into the telescope computers without
turning on X11 tunneling. Be sure to add the '-X' switch to your invocation
of ssh. Complete documentation on Remote Observing can be found
here. |

Stefanie Milam has submitted a CBET circular about her 12
Meter observations on the comet 73P. Here is the release:
Comet 73P/Schwassmann-Wachmann 3
S.N. Milam, A.J. Apponi, L.M. Ziurys, and S. Wyckoff, Arizona Radio
Observatory and Steward Observatory
Observations of the J=1-0 transition of HCN at 88.6 GHz were conducted
towards comet 73P component 'C' on April 11.36 UT with the Arizona Radio
Observatory 12m telescope on Kitt Peak, AZ. Two out of three hyperfine
components were detected with intensities of 0.035 +/- 0.005 K for the F=2-1
transition and 0.024 +/- 0.006 K for the F=1-1 line, with corresponding
linewidths of 1.0 +/- 0.2 km/s and 0.7 +/- 0.2 km/s, respectively. These
measurements indicate a total column density of ~3.4x10^{11} cm^{-2} for HCN
in the 'C' source of 73P. A production rate of Q(HCN) ~ 3x10^{25} s^{-1} was
calculated using a Monte Carlo model, assuming that this molecule is a
parent species arising from the nucleus. This transition of HCN appears at
the cometocentric velocity derived from the JPL Horizons ephemeris.

Turns out the brake was stuck engaged and not letting the
dome door motor move. Once free of the brake, it moved freely. George ground
a little clearance in the three tangs that engage in the frame of the motor.
Once reassembled the motor worked fine. Replaced drive chains for both
motors and tested. Dome door functions normally now. |

Because the dome door problem look like it will take a few
days to repair, we are warming up the receiver to try and unblock the JT
stage. |
