Venus Transit on Mauna Kea

A Venus Transit is a truly rare event. Transits occur in pairs eight years apart, with the next pair not occurring for another 120 years. The first event of the current pair occurred in 2004. Thus the next event will happen in June 2012. Considering the century long period between events, this is the last chance to witness a Venus transit during our lifetimes.

The 2012 event will be visible from the west coast of North America to Japan, China, Australia and Central Asia. For those wanting to observe the entire event from start to finish the choices narrow quite a bit. You have the choice of the Central Pacific, Japan, as well as Eastern China and Eastern Australia. This, of course, includes here in the Hawaiian Islands.

Many sky-watchers from North America will see only one choice if they wish to observe the event… the Big Island. The only place easily accessible by air, featuring excellent visitor accommodation, and an observing site that sits above the clouds that could so easily interfere with carefully laid plans. For the serious observer there is one obvious choice… Mauna Kea.

We saw the first signs of this well over a year ago. The tour companies that specialize in astronomy related travel, the folks that feature solar eclipse tours and similar events, began scouting Mauna Kea as a destination. Then the ads appeared, in Sky & Telescope magazine, Astronomy magazine, etc., “See the transit from Mauna Kea!” We had fair warning that this event was not going to pass peacefully.

Some folks seem to think the crowd will be huge, a thousand people or more. I am not so certain, this does not have the general appeal of a total solar eclipse. The transit is something that will be of interest to amateur astronomers and some interested segments of the public. I personally expect hundreds of people coming to Mauna Kea to view the transit, not thousands.

However many folks do ascend the mountain for this event, we have begun putting plans in place to handle it. Various groups have met to do a bit of planning. Most significantly, those in charge of managing the mountain, The Office of Mauna Kea Management, are putting a few measures in place. As usual, expect to stop at the Mauna Kea Visitor Information Station on the day of the transit. But this day there will be a few differences…

  • All available MKSS staff will be on duty. All of the Mauna Kea rangers and visitor station staff will be helping make sure assistance is available to visitors when traveling to the high altitude environment of the summit.
  • Access to the mountain will be controlled for the day, a gate at the VIS allowing access for official vehicles only.
  • A free shuttle will run from the VIS to the summit. The Mauna Kea tour companies providing the vehicles and drivers.
  • Solar telescopes and video monitors will be set up at the VIS to allow safe viewing. Staff will be available to answer questions and assists with the equipment.
  • Several other locations on the island will be setup for viewing the transit with solar telescopes and staff. Expect these to include ‘Imiloa, Keck HQ in Waimea, and some possible other locations.

All of these plans are somewhat preliminary, details may change as the date approaches and final arrangements are made. I will attempt to post what I know here on Darker View.

Myself? I plan to observe the event from the summit. Set up behind Keck with a solar telescope to photograph the transit. We plan to set up a live feed of the transit for use by other sites, and available to viewers across the internet.

WHAC Monthly Meeting

The West Hawai’i Astronomy Club Meeting is nearly upon us. As a reminder we will be at CFHT Headquarters this month. We have a guest speaker this month, so it should be a good evening…

Decoding starlight with infrared spectroscopy: Finding water in places where planets might form around new stars
Greg Doppmann, Keck Observatory
7:00pm, Feb 14th

Greg Doppmann is recent transplant to the Big Island, now working at the Keck Observatory as a Support Astronomer. He received his professional training in astronomy from the University of Texas at Austin. In addition to research, Greg was also active in infrared instrumentation for the McDonald Observatory while at Texas. After graduating in 2002, he took a postdoc position at NASA’s Ames Research Center.

In 2004, Greg moved down to La Serena Chile and became an instrument scientist at the Gemini Observatory. More recently, he was a member of the scientific staff at the National Optical Astronomy Observatory in Tucson for 5 years before moving to Hawaii.

His current research interests are focused on star formation, where he uses large telescopes with infrared spectrometers to measure physical properties of young stars that are embedded within nearby star forming clouds. In his spare time he enjoys hiking, cycling, gardening, and flying.

Science Illiteracy at the Star-Advertiser

We do like it when Keck Observatory is featured in the local papers. We are proud of the ‘scopes and take notice when we get some good press. The Star-Advertiser is the major daily paper for Honolulu and much of the state. I have even had some of my photographs published in the paper. Another article about Keck appeared today, but this time they simply display their ignorance of basic science.

Keck telescope helps discover 3 small planets outside Milky Way

The headline quickly had my attention. Exoplanet discoveries are coming fast with the Kepler Spacecraft / Keck Observatory team confirming alien worlds at a breakneck pace. It was the “outside the Milky Way” part that had my attention. I had no idea our current technology was capable of that! KOI-961 is a red-dwarf, a small, fairly dim class of star. It is difficult to even detect these stars at great distances, much less get the data needed to confirm orbiting planets. Something wrong here.

I double checked other sources… KOI-961 is actually fairly close to us in galactic terms, a mere 130 light years away. Given that the Milky Way Galaxy is well over 100,000 light years across, it puts KOI-961 well inside our galaxy. The article is actually reasonable, it appears to have simply taken the information from a press release, hard to screw up a cut and paste job. The headline however is where they stumbled hard.

Someone at the Star-Advertiser needs to take a basic astronomy course. Or maybe, simply check Wikipedia!

Update… They have fixed it. I forwarded the link to Larry O’Hanlon, the Keck PIO, whom I work with regularly. He called the S-A and apparently pointed out the issue. I would have loved to listen in on that conversation. The headline and text are edited now on the S-A website, but I kept a screenshot…

WHAC Visits Gemini and CFHT

There are few opportunities to visit most of the telescopes on Mauna Kea. Only two of the thirteen telescopes maintain any sort of regular public access. Keck opens a viewing gallery during business hours on weekdays and to the MKVIS weekend tours. Subaru provides interior tours, but only with advance reservations. Visiting inside any of the other telescopes is normally not open to the general public, but can be arranged with some work.

Thanks to the work of a few individuals the West Hawai’i Astronomy Club arranged tours of both Gemini and CFHT. Marc Baril was kind enough to arrange the CFHT tour, setting up staff and transportation for the visit. This included a pair of CFHT 4WD vehicles taking folks from Waimea to the summit. Many thanks are owed to Joy Pollard who set up the Gemini portion of the tour. Weekend tours are not normally arranged, but Joy managed to put together the needed staff to allow us to visit the telescope on a Saturday. The result was a couple great tours of these facilities.

Arriving at CFHT
Arriving at a very foggy summit to visit Gemini and CFHT
This marks the second recent summit tour available to members of the West Hawai’i Astronomy Club. Last year we toured the W.M. Keck Observatory. This year CFHT and Gemini allowed us to view a pair of telescope that have helped keep Mauna Kea at the forefront of astronomy for decades.

The weather was pretty awful, winter weather closing in on the summit for the last couple weeks. We arrived at the summit to encounter patchy snow, dense fog and a bitter chill. This would not be an opportunity to enjoy the stunning vistas or sunset that the summit of Mauna Kea is renowned for, we could barely see the next telescope, much less the sunset. At least the road was open to the public and our tour could go on.

We convened in the control room of the Gemini telescope. Here our guides, Joy and Sonny, explained the operation of the telescope and how the operators controlled everything through the night. Our tour of Gemini ran a bit longer than the scheduled hour. During that hour we toured the control room, the coating facility, and the telescope itself.

Gemini Control

In contrast to many of the other telescopes on the mountain, Gemini is an almost new facility, having seen first light in 1999 and begun science operations in 2000. It is a beautiful telescope, the 8.1 meter instrument sits in a spacious dome. As someone who’s experience has been that a productive environment is always bit messy, the clean facility of Gemini seems a bit odd.

A few levels below the main dome floor is the coating facility. This is where the telescope mirror receives a new reflective surface very few years. For a single piece eight meter primary, a vacuum chamber slightly larger is required. The large chamber makes it seem as if there is a flying saucer docked in the lower bay of the telescope building. The many viewing ports and vacuum lines simply adding to the impression.

After Gemini it was on the CFHT… The contrasts between the telescopes was dramatic. CFHT is a facility that shows the scars and wear of decades of research. There was an eclectic mix of new equipment intermingled with gear that had been running for over thirty years since the telescope began operations in 1979. This is a facility that started recording observations with photographic plates, along the way making the transition to electronic CCD image sensors. The telescope now boasts one of the world’s largest cameras, the 340 megapixel MegaCam.

Again we visited the coating facility, complete with the massive cranes and the vacuum chamber needed to coat mirrors up to three and a half meters in diameter. This facility is also used by the IRTF and UKIRT observatories to coat the primary mirrors for those telescopes. A treat for me was visiting the OHANA interferometer test lab in the coudé room below the telescope. A project I knew a fair amount about, but had never seen.

The tour finally arrived at the telescope itself. The large equatorial design is such a contrast to the alt-azimuth designs of the more modern designs of Gemini, Subaru and Keck. The enormous steel horseshoe and yoke represent a classic design used for large telescopes throughout the 20th century. We wandered about the dome floor, learning about the details of the telescope, the drives, and the instruments. The AO system was scheduled for the night and was mounted to the telescope. While the massive MegaCam prime focus camera was sitting to the side of the telescope.

The hoped for view of sunset from the upper balcony of the CFHT telescope was nothing to write about. Clouds obscuring all but a hint of sunset’s colors. The final treat was instead an opportunity to ride the rotating dome while the telescope slewed. The show highlighted this big machine, a testament to the people who build and operate these telescopes to push the boundaries of human knowledge deep into the universe.

These tours take a fair amount of work to put together, but are very much worth it. I expect we will do another tour in the spring. Perhaps do a couple of the radio telescopes? CSO, JCMT or SMA? Personally I have never had a chance to properly appreciate the sub-millimeter observatories on the summit. CSO is due to be dismantled in a couple years, it would be a good time to visit this groundbreaking facility.
