Up top giving some family a tour of the telescopes. We stayed for sunset, it was worth the wait…
Postcard from the Summit – Another Mauna Kea Sunset

TMT Permit Approved
The Conservation District Use Permit (CDUP) for the Thirty Meter Telescope has been granted. The Hearing Officer’s report is published and available for reading. And it is interesting reading! Quite oddly I do enjoy reading these legal documents, I have learned much about the summit through the various documents like this.
There are numerous claims that seem quite odd to anyone familiar with the summit, claims that were easily disproved during the investigative process. An “extensive fencing network”? What fences? Anyone who has visited the summit knows that there are no fences around the observatories at the summit. There are some small enclosures necessary to keep people safe around storage tanks and such. Well below the summit the VLBA antenna is enclosed for safety reasons, as is an electrical substation at Hale Pohaku.
49. Petitioners contend that a purported “subdivision” of land among the various existing observatories is evidenced by an “extensive fencing network.” Exhibit A-202 at 22. As was plain during the site visit, there is no “fencing network,” much less an “extensive” one, in the summit region of Mauna Kea.
Claims that the TMT would negatively impact the waters of Lake Waiau? The TMT is not located anywhere near the lake’s watershed. The petitioners engaged in legal mudslinging, throwing as many claims as possible at the case to see what would stick, a legal tactic I dislike immensely. Making such unfounded claims merely serves to discredit the petitioners, distracting the conversation away from the real issues involved in sharing the summit region.
466. Considering all of the evidence, including but not limited to the testimonies of Drs. Liu and Kauanui, and giving such evidence due weight, Petitioners have not offered reliable, probative, substantial, or credible evidence, scientific or otherwise, to suggest that the Project will be harmful to the health, safety, and welfare of native Hawaiians or anyone else.
There are reasonable cultural objections to the use of the mountain for astronomy. These are what must be addressed in this process. Can use of the summit be shared among the various parties? The report clearly comes to the conclusion that we can share the summit and that the presence of the new telescope can be minimized through proper measures.
101. Petitioners did not offer reliable, probative, substantial, and credible evidence, whether from expert or lay witnesses, that would support the conclusion that the TMT Project would cause substantial adverse impact to plants, aquatic life and wildlife, cultural, historic, and archaeological sites, minerals, recreational sites, geologic sites, scenic areas, ecologically significant areas, or watersheds.
There is a list of conditions, which seem quite reasonable… The staff must receive cultural and environmental education on the special nature of the summit of Mauna Kea. We do this at Keck, something I usually find quite interesting. They must use a completely enclosed waste water system. There must be an invasive species plan. Conditions around the construction site must be monitored, including arthropod populations, during construction and for two years afterwards. There is an extensive list that goes on from here…
e. The proposed land use, including buildings, structures, and
facilities, will be compatible with the locality and surrounding areas, appropriate
to the physical conditions and capabilities of the specific parcel or parcels
Will this be the end of the legal process? No. There is an additional hearing for the petitioners to take place before the Hearings Officer so that both sides may review the findings. It is also likely that at least one lawsuit will be filed in reaction to issuance of the CDUP. Unless there is some new legal issue these are unlikely to progress very far. The process so far has been quite exhaustive, any further legal action would simply be a rehashing of what we have already heard.
Postcard from the Summit – Walking to the True Summit
It has been many years since I last stood atop the summit of Mauna Kea, the true summit that is. A couple decades ago, while on vacation I walked to the summit as a tourist. All these years of driving past on the way to work, I have not stopped and taken the short walk to the summit of Mauna Kea from the road, until now.
Broken gear on a weekend, driving up the mountain by myself. Once the gear was fixed I was free to head back down. Without a vehicle full of guys just wanting to go home after a full day at work, I was free to stop and take a walk with the camera…
Night of The Dobs
Star parties at Hale Pohaku are very informal affairs. You never really know who is and who is not going to show up. We just don’t plan that much.
It had just been too long, I had not had a good night out with the telescope for months. This dark moon Saturday was not going to be missed, I packed up Deep Violet and headed for The Mountain. I knew a few folks would be there, certainly Cliff and Tony. The rest of the folks were a surprise to me. As the evening progressed more and more ‘scopes showed up, a few more familiar voices in the darkness.
The only real issue was the wind, it was annoying. A couple of us moved our telescopes into the patio area of the MKVIS, where the building offered some shelter at the expense of blocking some of the sky.
UFO over Mauna Kea? Not!
There is a battery of webcams atop Mauna Kea, a few of which feature good sensitivity and are useful after dark. The telescope operators depend on these cameras to evaluate conditions around the telescopes during observation. From the warm control rooms, they can see clouds overhead, or even fog blowing over the summit.
The imagery from the Mauna Kea cameras is publicly available, a very useful feature to those of us who live and work around the mountain. But there are others use this video, looking for things that those who install and operate the cameras did not intend.
A video showed up recently, purported to show a UFO maneuvering over Mauna Kea. The camera is again the CFHT Cloudcam, a very nice camera installed to give CFHT operators a good look at approaching weather. The high quality images of this camera have occasionally shown odd events in the sky. Back in June the camera recorded a strange expanding halo of light that was eventually linked to the launch of a Minuteman Missile from Vandenburg AFB.
OK, just a dot of light that appears then fades, not very impressive. Particularly interesting is that the dot of light does not move with respect to the camera. To me this suggests some nearby fixed source of light that entered the camera from another angle. Another reasonable possibility is a geostationary satellite glinting in the sun. Making this out to be a UFO is a stretch by any measure.
Dusty Road
Rush hour for Mauna Kea is just before sunset. This is when the day crews are coming down, while the summit tours and telescope operators are heading up.
The timing of this rush can be variable depending on time of year and what time sunset occurs. Twice a year this rush is at its worst, when everyone heads up and down at the same time. This can lead to some difficult driving conditions… A lot of vehicles on a road that can be challenging. A cloud of fine cinder dust and a setting Sun just adding to the confusion…

Astrophoto Interference on Mauna Kea
Mauna Kea is simply a great place to shoot astrophotos from. Dark, clear skies with typically good seeing. Unlike some mainland locations there is a distinct lack of aircraft overhead. I am not sure how many shots I have had ruined by the bright anti-collision strobes crossing through the frame when shooting from locations in Arizona.
There are hazards to shooting photos here that do not commonly exist elsewhere. I was unpleasantly surprised when reviewing the take the next morning to find brilliant yellow lines through a hour and a half of exposures taken of the Cygnus region. The material is otherwise great, the makings of a nice shot, except for this one little issue. There are ways of suppressing artifacts like this when processing, but the beam is so bright I am not certain they will work all that well.
Worse, I checked the schedule, the offending laser is coming from Keck 2 AO, a system I work on.
The observatories have a system in place to deal with this issue. There are four operational lasers on the mountain, Keck 1 and Keck 2, Subaru and Gemini. Each optical observatory using a laser maintains a server that posts their laser location, status, and calculates the position of each beam in the sky. This can be queried by the other observatories to check if the beam crosses the field of view. A set of rules has been negotiated to determine who has right of way, usually who is on target first.
Obviously this computer system does not take into account my little telescope shooting photos from Hale Pohaku. If I had known I could have called Heather and asked her to shutter her laser, I was on target first. Being the kind soul she is, she would probably laugh with me.
