Later that same day

I took the top photo on my way to work one early morning. It’s a tranquil scene (the reason I go down there) shot from the beach below Pu’ukohala Heiau in Kawaihae. The second photo was shot on my way home in mid-afternoon. It was taken from the same beach in roughly the same place and looking in roughly the same direction.

Astute observers will see past the similarities in the photos and notice something is missing. Hualalai Volcano has disappeared. Now, it’s not unreasonable to think that those puffy white clouds in the second photo have something to do with this, but that’s not really the case. True, they might mask the upper reaches of the volcano, but the whole thing? No, the culprit is the fuzzy band between the clouds and the land – vog!

The latest eruption of Kilauea Volcano, which began on September 29th, is churning out vog, which forms when volcanic gases interact with sunlight, air, moisture, and dust. Two days later, when these photos were taken, it was having a visible effect. I’d noticed the vog drifting up the west side of the island during the morning and by afternoon visibility was greatly reduced. But it’s not just visibility that’s affected. Vog is especially troublesome for people with breathing difficulties, but can also irritate the eyes and skin of just about anyone.

Kilauea erupts again

Activity at Kilauea in April 2018

Yesterday afternoon, around 3:20 p.m., Kilauea Volcano began a new eruption. Like the previous one, from December 2020 to May 2021, the eruption is in Halemaʻumaʻu crater, at the summit of the volcano. That eruption created a lava lake in an area that collapsed in 2018 when the main activity moved down the east rift zone to the Leilani Estates Subdivision. This new eruption has reactivated the lake in the crater.

These photos are from the 2018 activity in Halemaʻumaʻu crater shortly before the level of the lava lake dropped and the crater floor collapsed.

Sunrise over Kohala Mountain

This week’s Sunday Stills challenge theme is ‘Signs of Autumn.’ See more responses here.

We’re a little short on autumnal changes here. I tend to mark seasonal changes in terms of wildlife, such as the return of humpback whales in winter. For autumn, the return of Pacific golden plovers from their summer breeding grounds in Alaska is probably the most notable.

Outside of wildlife, the shortening of the days does register here. It’s not as dramatic as when I lived in Washington State, with summer sunsets around 9 p.m. and winter darkness setting in a little after 4 p.m.. In Hawaii, the equivalent times are 7 p.m. and 6 p.m., not such a big difference.

But it does make a difference for my morning commute, and autumn signals the time when I usually leave home when it’s mostly dark and arrive at work when it’s mostly light. I also try and give myself a little extra commuting time so I can pull over and take photographs when the sunrise merits it, such as this streaky red sunrise over Kohala mountain.

Red-masked parakeets

I’ve lived in Hawaii for more than nine years now and had previously never seen any of those most tropical of birds, the parrots. One reason for this is that parrots aren’t native to Hawaii, but a variety of different parrots have become established here.

Red-masked parakeets were first seen here in 1988 and are probably the most common parrot on the Big Island. They’re natives of Ecuador and Peru, but are now fairly well established on the Kona coast, which is where I saw this a pair, in Kohanaiki Beach Park. While they forage along the coast here, they roost high up on the slopes of Hualalai Volcano.

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.

Mauna Ulu

This week’s Sunday Stills challenge theme is ‘Burlywood.’ (See more responses here.) It’s a color I’d never heard of before, apparently a shade of khaki. I’ve gone for some photos of Mauna Ulu, a crater in Hawaii Volcanoes National Park.

The Mauna Ulu eruption took place between 1969 and 1974 and transformed the landscape of the park. A good guide to the eruption can be found here. These days, it’s a quiet area and plants have gained a foothold in the main crater, though the slopes are still mostly barren. And it’s those slopes, seen from the air, that have a pronounced khaki, or burlywood color.
