HET still operating, partially remotely

In response to COVID-19, the HET operations team has been rapidly developing our remote observing capabilities. At present, the night observations are staffed by one telescope operator on site and a remotely-connected resident astronomer (staying at home). Our afternoon operations shift is also being staffed remotely (one remote TO and one remote RA), requiring about 20-30 minutes of assistance from one member of day staff on site for our routine safety checks. Some day time staff are able to work partially or fully remotely from home, but most are still coming in daily as their duties cannot be done over a remote connection. Extra attention is being paid to hygiene, cleanliness, and staff presence each day. To further minimize risk, we have temporarily suspended our schedule of primary mirror segment swaps, as that process requires two members of the mirror team working in very close proximity with each other. We are benefiting from a lot of “can-do” attitudes here and receiving extensive help from our software team to get remote access and learning a lot in this process! After this is all over, I expect we’ll see long-term benefits from the things we have learned throughout this interesting time.

Open position: Resident Astronomer

This advertisement was posted on February 17th 2020, and applications received by March 31st will be fully considered.

 

The University of Texas at Austin, McDonald Observatory invites applications for a Resident Astronomer for the Hobby-Eberly Telescope (HET) in the beautiful Davis Mountains of west Texas. The HET is a fully queue scheduled 10-m class optical and near-IR spectroscopic telescope located 6,600 feet above sea level. The observing queue is run by the team of Resident Astronomers who serve as on-site observing specialists, generally each working about 7-10 nights per month. Currently the facility instruments include the Visible Integral-field Replicable Unit Spectrograph (VIRUS), the Low-Resolution Spectrograph 2 (LRS2), and the Habitable-zone Planet Finder Spectrograph (HPF). All together, this powerful suite of spectroscopic instruments on one of the world’s largest optical telescopes enables a diverse range of research possibilities.

The Resident Astronomer position includes up to 25% time for personal research and funds to support research (computing, travel, publications, etc).

 

Key responsibilities of the position include:

  • Leading nightly science observations safely and efficiently from sunset to sunrise.
  • Working with the HET partner scientists to verify the integrity and quality of the observations and help optimize the scientific productivity of the facility.
  • Working with instrument scientists and engineering staff to maintain and document the performance of the HET and its instruments.
  • Documenting the current status of science operations through wikis and web pages.
  • Conducting projects to characterize and/or improve science operations.
  • Up to 25% of the work hours are available to conduct personal research and to contribute to the scientific life at the observatory.

Short term DIMM outage

As of Wednesday Feb 12th, the DIMM (Differential Image Motion Monitor) telescope is temporarily out of commission due to a technical problem. We usually run this telescope (mounted a few hundred feet from the HET on a platform to monitor native site seeing) while observing and provide the DIMM image quality (seeing) measurement to PIs with their observations. However these measurements will be temporarily unavailable while we are fixing the issue.

Internet outages recently, getting back to normal now

Currently (Wednesday January 29th, 2020), things appear to be normal again, but we’ve been experiencing issues with internet/network connectivity over the past few days.   In the early morning hours of Sunday January 26th (around 5am) we lost all network/internet access on site.  Some access was restored that evening around 9:45pm, but connections were spotty, inconsistent, and some functions were not working.  This affected our real-time data transfers from HET to TACC and has prevented some users from editing their observing programs. All of this functionality appear to have been restored at this time, but if you have any issues please get in touch with us to help.

New Position: July 25, 2018 – Opto-mechanical technician

*** As of November 26th, 2018, this position has been filled ***

McDonald Observatory at The University of Texas at Austin, has an opening for an opto-mechanical technician at the Hobby-Eberly Telescope (HET); a state-of-the-art optical telescope facility located in the Davis Mountains of West Texas, 16 miles from Ft. Davis, Texas (440 miles west of UT Austin campus). This position is responsible for maintaining the many optical systems throughout the facility with the principal focus on the large (10 meter), multi-segmented (91 mirrors), primary mirror. Maintaining the primary mirror involves removing and installing individual segments (swapping) as well as sustaining the critical peripheral systems required to support this array. The critical support systems include 1) the Segment Alignment and Maintenance System (SAMS), a sensor system that measures the figure of the primary mirror 2) the Segment Control System (SCS), a motor driven positioning system for each of the individual mirror segments and 3) the mirror frame, a mechanical system designed to hold each segment in place. Other work includes supporting the mirror coating process and thorough record keeping to document the work performed and the state of the various subsystems.

Required qualifications: Bachelor’s degree in science or engineering, or a related field; equivalent combination of relevant education and experience may be substituted as appropriate. Preferred qualifications: Two years experience working with optical systems and/or a laboratory environment. Math skill set including linear algebra and calculus. Computer skill set including programming fundamentals, MATLAB, LabView. Ability and/or experience with directing and/or managing projects.
