Balloon Cams Will Offer Unparalleled Views of the Total Solar Eclipse

The August 2017 total solar eclipse should be visible to some degree from just about everywhere in the continental United States—that is, if the weather cooperates. But now, even if it doesn't, everyone will be able to watch along, thanks to livestreamed video from balloon cams drifting miles above the Earth.

Astrophysicist Angela Des Jardins of Montana State University (MSU) got the idea to monitor the magnificent cosmic event from the air after reading about an airplane pilot's flight through the path of a 2013 eclipse. She thought her students might enjoy the chance to get an up-close look for themselves.

But what started as a class project quickly, well, ballooned. At last count, teams from more than 50 other schools had joined the Eclipse Ballooning Project. The core of the work remains close to home; MSU students have designed, built, and tested the equipment, and even offered multi-day training for students from other schools. Undergrads in the computer science and engineering programs even created the software that air traffic controllers will use to track the balloons on the big day.

The next step was to get the balloon cam footage to a larger audience. Seeing no reason to think small, Des Jardins went straight to the source, inviting NASA and the website Stream to join the fun. The space agency is now beefing up its website in anticipation of 500 million livestream viewers.

And what a view it should be. The balloons will rise more than 80,000 feet—even higher than NASA's airplane-mounted telescopes.

"It's a space-like perspective," Des Jardins said in a press statement. "From that height you can see the curvature of the Earth and the blackness of space."

Online or outside, Des Jardins says viewers can expect a kind of "deep twilight, with basically a 360-degree sunset" during the eclipse.

She urges everyone to get outside if they can to see the event with their own eyes, but expects the balloon cams will deliver something really special.

"On the ground, an eclipse just kind of happens to you. It just gets dark," Des Jardins told New Scientist. "From the air, you can see it coming and going. I think that perspective is really profound."

How to See the Full Sturgeon Moon on Thursday

The full moon of every month has a special nickname. Some—like September's harvest moon, December's cold moon, and May's flower moon—have obvious connections to their seasons, while other names are harder to decode. August's sturgeon moon is an example of the latter. It may not be the prettiest lunar title in The Old Farmer's Almanac, but that doesn't mean the event itself on August 15, 2019 won't be a spectacular sight to behold.

What is a Full Sturgeon Moon?

The first (and normally the only) full moon that occurs in August is called a sturgeon moon. The name may have originated with Native American tribes living around the Great Lakes in the Midwest and Lake Champlain in New England. These bodies of water contain lake sturgeon, a species of freshwater fish that grows up to 6.5 feet in length and can live 55 years or longer. August's full moon was dubbed the sturgeon moon to reflect its harvesting season. This full moon is sometimes called the green corn moon, the grain moon, and the blackberry moon for similar reasons.

When to See the Full Sturgeon Moon

On Thursday, August 15, the full sturgeon moon will be highly visible around sunrise and sunset. The satellite will be 99.9 percent illuminated by the sun when it sets Thursday morning at 5:57 a.m EDT—just nine minutes before dawn. On the West Coast, the setting moon will coincide perfectly with the rising sun at 6:15 a.m. PDT.

If you aren't interested in getting out of bed early to catch the sturgeon moon, wait until Thursday evening to look to the horizon. Twenty-seven minutes after sunset, the full moon will rise on the East Coast at 8:21 p.m. EDT. On the West Coast it rises at 8:10 p.m. PDT, 30 minutes after the sun sets.

The moon generally looks bigger and brighter when it's near the horizon, so twilight and dawn are ideal times to catch the spectacle. But it's worth taking another peek at the sky closer to midnight Thursday night; the Perseid meteor shower is currently active, and though the light of the moon may wash them out, you're most likely to spot a shooting star in the late night and early morning hours.

A Full Harvest Moon Is Coming in September

The Old Farmer's Almanac lists a special name for every month's full moon, from January's wolf moon to December's cold moon. Even if you're just a casual astronomy fan, you've likely heard the name of September's full moon. The harvest moon is the full moon that falls closest to the fall equinox, and it's associated with festivals celebrating the arrival of autumn. Here's what you need to know before catching the event this year.

What is a harvest moon?

You may have heard that the harvest moon is special because it appears larger and darker in the night sky. This may be true depending on what time of night you look at it, but these features are not unique to the harvest moon.

Throughout the year, the moon rises on average 50 minutes later each night than it did the night before. This window shrinks in the days surrounding the fall equinox. In mid-latitudes, the moon will rise over the horizon only 25 minutes to 30 minutes later night after night. This means the moonrise will occur around sunset several evenings in a row.

So what does this mean for the harvest moon? If you're already watching the sunset and you catch the moonrise at the same time, it will appear bigger than usual thanks to something called the moon illusion. It may also take on an orange-y hue because you're gazing at it through the thick filter of the Earth's atmosphere, which absorbs blue light and projects red light. So if you've only seen the full harvest moon around sunset, you may think it always looks especially big and orange, while in reality, any full moon will look that way when it's just above the horizon.

When to See the Harvest Moon

This year, the harvest moon will be visible the night of Saturday, September 14—about a week before the fall equinox on September 23. The moon will reach its fullest state at 12:33 a.m. ET—but if you're still convinced it's not a true harvest moon without that pumpkin-orange color, you can look for it at moonrise at 7:33 p.m. on September 13.
