Eclipse chasers take three different routes to totality

NASHVILLE, Ind. — There’s nothing like a total solar eclipse to remind you of the unstoppability of nature — and the tenuousness of technology.

Not that we need much of a reminder: The challenges of climate change, ranging from floods to wildfires, and the problems caused by the coronavirus pandemic amply show the limits of humanity’s control over nature.

But chasing totality is a more benign example showing just how hard it is to predict which paths Mother Nature will take, and how technology may or may not catch up.

It was tricky to pinpoint the best place to see today’s total eclipse, because totality was visible only along a narrow track stretching from Mexico to Newfoundland, for no more than four and a half minutes over any location. If clouds roll in at 3:04 p.m., and totality begins at 3:05, there’s nothing OpenAI or SpaceX can do about it.

Based on historical precedent, a stretch of Texas around Austin was supposed to have the best chance of clear skies. Here in Nashville, a well-known tourist destination south of Indianapolis, the cloud-cover predictions varied from totally sunny to as much as 60% clouded over. Meanwhile, some air travelers hoped to catch sight of the blacked-out sun as they flew above the clouds. How did it all turn out? Check out three tales from GeekWire’s eclipse team.

Your (nearly) last-minute guide to the solar eclipse

It’s prime time for eclipse-chasers: A total solar eclipse will trace a line from coast to coast on Monday, and the anticipation is at its peak. So are the travel costs.

Hard-core eclipse fans made their travel arrangements long ago. That was also the case back in 2017, when a similar all-American solar eclipse turned central Oregon into one of the nation’s hottest hotspots (made even hotter by that summer’s wildfires). Witnessing a total solar eclipse in person is something everyone ought to do at least once in their life, and if you want to get in on the experience this time around, it’s still possible.

I should know: That’s exactly what I’m doing.

Fireball lights up Seattle’s skies as webcams watch

It’s cool to see a fireball — but even cooler to capture it on video. At least that’s the way Seattle engineer/photographer Corey Clarke sees it.

Clarke’s webcam happened to be pointing in the right direction to record the fireball’s flash through wispy clouds at around 11 p.m. PT Monday night. His day job at ServiceNow focuses on hardware reliability, but he’s also a photographer who specializes in wildlife shots, landscapes and views of the night sky.

How to see the total lunar eclipse in the sky and online

If you’re on the West Coast, watching tonight’s total lunar eclipse will require a willingness to stay awake in the middle of the night — plus a lucky break on the weather.

But maybe it’s worth taking a chance: The next opportunity to take in the sight of a blood-red, eclipsed moon won’t come until 2025. And even if it’s cloudy, you can hedge your bets by tuning in NASA’s live stream of the event.

Lunar eclipses occur when Earth and the moon are positioned such that our planet blocks out the sunlight falling on the lunar surface. During a partial eclipse, only a portion of the moon goes dark. Totality occurs when the moon passes directly through the darkest part of Earth’s shadow, known as the umbra.

The partial phase of tonight’s eclipse begins at 1:44 a.m. Tuesday, with totality lasting from 2:17 to 3:42 a.m. During the total phase, the only light falling on the moon’s near side will come from the reddish light refracted by Earth’s atmosphere. Put more poetically, it’s the light from countless sunrises and sunsets.

How to make the most of the Supermoon eclipse

The only total lunar eclipse of 2021 will also be one of the shortest total lunar eclipses in recent years, lasting just less than 15 minutes. And it’s not exactly the easiest one to see in the Seattle area, due to its timing as well as the weather.

Earth’s shadow will start creeping across the full moon’s disk at 1:47 a.m. PT on May 26, and the eclipse will reach totality at 4:11 a.m. Because this particular eclipse has the moon passing so close to the edge of Earth’s umbra — that is, the shadow’s darkest part — the moon starts brightening up again at 4:25 a.m. in the dawn’s early light.

The forecast for Western Washington poses even more of a challenge for skywatchers. “Conditions not looking favorable at this time,” the National Weather Service’s Seattle bureau told me in a tweet. Even if it’s not actually raining, overcast skies could well spoil the view.

“Best advice at this time is to a) get some elevation above low clouds or b) go east of the Cascade crest,” forecasters said.

After sky show, SpaceX picks up its rocket droppings

The atmospheric re-entry and breakup of a SpaceX Falcon 9 rocket upper stage created a fiery display in the skies above the Pacific Northwest a week ago, but not all of those shooting stars burned up on the way down.

At least one big piece of the rocket — a roughly 5-foot-long composite-overwrapped pressure vessel — fell onto private property in southwest Grant County in Central Washington, the county sheriff’s office reported today in a tweet.

Kyle Foreman, a spokesman for the sheriff’s office, told GeekWire that the property owner left a message reporting the debris last weekend. Based on the reports about March 25’s meteor show, SpaceX’s rocket re-entry loomed as the likeliest cause for the commotion.

“The sheriff’s office checked it out on Monday, and SpaceX staff came over on Tuesday and retrieved it,” Foreman said.

He was unaware of any other reports of fallen rocket debris — and in its tweet, the sheriff’s office made clear that it considered the case closed. “Media and treasure hunters: we are not disclosing specifics,” it said. “The property owner simply wants to be left alone.”

Pacific Northwest meteor mystery gets solved quickly

Was it a meteor? A broken-up satellite? Maybe a UFO? Leave it to an astronomer to identify what caused the light show that was visible over a wide stretch of the Pacific Northwest around 9 p.m. PT tonight.

Jonathan McDowell, an expert satellite-tracker at the Harvard-Smithsonian Center for Astrophysics, quickly figured out that the meteoric display was actually the breakup of a SpaceX Falcon 9 rocket stage, left over from a launch that took place three weeks ago.

“The Falcon 9 second stage from the Mar 4 Starlink launch failed to make a deorbit burn and is now re-entering after 22 days in orbit,” McDowell tweeted.

It’s fitting that the re-entry of a rocket stage from a Starlink satellite launch provided a moment of marvelment from Seattle to Portland and beyond. After all, those satellites are manufactured at SpaceX’s facility in Redmond, Wash., and it’s conceivable that members of the Starlink team caught the show.

Jupiter and Saturn pair up to make a Christmas Star

Are you ready for a remake of the Christmas Star story? Depending on how much stock you put in historical hypotheses, this year’s solstice on Dec. 21 could bring a replay of the phenomenon that the Three Kings saw in the Gospel of Matthew.

That’s when Jupiter and Saturn can be seen incredibly close together in the night sky. If the skies are clear, the two planets will be hard to miss in southwest skies just after sunset, as seen from mid-northern latitudes. Jupiter will sparkle brighter, and Saturn will be shining only a tenth of a degree to the upper right. With a small telescope, you might be able to see both planets and their moons in a single field of view.

“Some astronomers suggest the pair will look like an elongated star, and others say the two planets will form a double planet,” NASA says in a blog posting about the Dec. 21 conjunction. “To know for sure, we’ll just have to look and see. Either way, take advantage of this opportunity because Jupiter and Saturn won’t appear this close in the sky until 2080!”

Geminids could be a gem of a meteor shower

The stars have aligned for this weekend’s peak of the annual Geminid meteor shower. Now let’s hope that the weather aligns as well.

Skywatchers rank December’s Geminids alongside August’s Perseids as the year’s highlights for meteor shows. Under peak conditions, sharp-eyed observers can see two meteors a minute. NASA notes that the shooting stars are bright and fast, and tend to be yellow in color.

But the strength of the show is highly dependent on viewing conditions. In some years, the moon’s glare washes out the night sky so that few meteor streaks stand out.

One of the few good things about 2020 is that the moon won’t interfere this year. It’s nearly a new moon, which means skywatchers will see only a thin crescent that rises in the east just before dawn.
