The sun rises behind Mauna Kea, coloring the sky, and backlighting the telescopes at the summit.

Snow on Mauna Kea
We had a weird weather system settle on the island recently, which provided a week of cloudy, wet weather. It also deposited a decent snowfall on the top of Mauna Kea, which stuck around for a fair while. Maybe it will be a white Christmas after all!

Subaru Telescope visit
This week’s Sunday Stills challenge theme is ‘Going Back….’ See more responses here.
I was thinking about posting photos going back to my first visit to Hawaii, but in looking at them, I realized that I’d never posted photos from my tour of the Subaru Telescope, which I took a few months after moving here. At the time, the Subaru Telescope was the only one on the summit of Mauna Kea that offered tours to the general public, though the tours have been shut down by the current Covid situation.
I particularly remember the fabulous views from the walkway around the exterior of the telescope. The interior of the telescope was also interesting, though in the abstract way of a giant piece of equipment. This is not a telescope where one gets to put an eye to the lens to see what’s going on, though I was charmed to learn that when Princess Sayako of Japan dedicated the telescope in 1999, she was able to do just that because a special eyepiece had been constructed for that purpose!
The Subaru Telescope is a Ritchey-Chretien reflecting telescope. It has a large field of view which makes it ideal for wide-field sky surveys. For more information about the Subaru Telescope, visit https://subarutelescope.org/en/. The telescope’s live camera stream captured a cool video of last month’s Perseid Meteor Shower which can be seen here.
Atop Mauna Kea
This week’s Friendly Friday challenge theme is ‘Mountain Top.’ See more responses here.
Mauna Kea is the highest mountain on earth, when measured from its base to its peak. It logs in at 33,476 feet, 13,803 of which are above sea level.
The top photo is a late afternoon view from near the summit of Mauna Kea, with the Subaru Telescope on the left and the two Keck Telescopes to the right. The top of the cloud layer lies a thousand or more feet below them, which is one of the reasons it’s such a prime site for astronomy.
The second photo is a view from Upolu, showing the summit with a lot of snow on it. While this photo was taken in February, the volcano is high enough that snow can fall at any time of year.
View of Mauna Kea
There are 13 telescopes atop Mauna Kea, but while they’re all one of a kind in that regard, they vary in how they make observations. Some collect visual light, some infrared. Others are used for radio astronomy. I’d go in to more detail about this, but the science is as far over my head as the telescopes are in this photo!

I see this stand of yuccas on the drive into Waimea and watch for it to bloom. When it does, late afternoons are the best time for photographs so I try to remember to stop on the way back from hiking off Saddle Road or at Hawaii Volcanoes National Park. In this instance, it was the latter, and I was passing by around 6 pm.
Look closely at the top photo and the telescopes of Mauna Kea can be seen in the distant background, which is a bit unusual for this time of day, morning being their time to shine.
