Astronaut Records Elusive "Blue Jet" Lightning From Space

During his mission aboard the International Space Station in 2015, Danish astronaut Andreas Mogensen captured a dramatic weather phenomenon that’s rarely seen from Earth. As Mashable reports, his footage below is the clearest look we have at “blue jet” lightning.

Blue jets form when lightning bolts spring from the tops of thunderclouds, shooting 25 to 30 miles up. Even from a vantage point in the Earth’s orbit, the flashes can be difficult to document. Mogensen recorded this video using highly sensitive camera equipment aboard the ISS.

During the 160 seconds of footage taken above the Bay of Bengal, 245 blue flashes of electricity were captured. The film provides an unprecedented look at a weather phenomenon meteorologists still know little about. The European Space Agency (ESA) is now planning to mount a camera outside their Columbus laboratory aboard the ISS that will monitor thunderstorms around the clock. In addition to giving us more data about blue jets, future footage could provide valuable information about other types of upper-atmospheric lightning like red sprites, pixies, and elves.

How Waffle House Helps Measure the Severity of a Natural Disaster

There are a lot of ways the Federal Emergency Management Agency (FEMA) assesses and addresses the severity of a natural disaster. Meteorology can predict movement patterns, wind gusts, and precipitation. Resources are dispatched to areas hit hardest by torrential weather.

But when the agency needs an accurate, ground-level gauge for how a community is coping during a crisis, they turn to Waffle House.

Since 2004, FEMA has utilized what former administrator Craig Fugate called the “Waffle House Index.” Because the casual dining chain is open 24 hours a day, seven days a week, tracking to see if a location is closed or working with limited supplies can help inform the agency as to whether affected areas are ailing or taking steps toward normalcy.

“If a Waffle House is closed because there's a disaster, it's bad,” Fugate told NPR in 2011. “We call it red. If they're open but have a limited menu, that's yellow ... If they're green, we're good, keep going. You haven't found the bad stuff yet.”

For FEMA, the ability to order a plate of smothered and covered hash browns is an important analytic. If a Waffle House is having trouble getting stock, then transportation has been interrupted. If the menu is limited, then it’s possible they have some utilities but not others. If its locations have locked their doors, inclement weather has taken over. The chain’s locations would normally stay open even in severe conditions to help first responders.

The company has opened a Waffle House Storm Center to gather data in anticipation of Hurricane Florence, a Category 2 storm expected to touch down in the Carolinas this week. But not all locations are taking a wait-and-see approach. One Waffle House in Myrtle Beach, South Carolina has already closed due to the looming threat, making it the first red dot on the Index.

See What Hurricane Florence Looks Like From Space

As Hurricane Florence continues to creep its way toward the Carolinas, it’s repeatedly being described as both "the storm of the century” and "the storm of a lifetime” for parts of the coastlines of North and South Carolina. While that may sound like hyperbole to some, Alexander Gerst—an astronaut with the European Space Agency—took to Twitter to prove otherwise with a few amazing photos, and issued a warning to “Watch out, America!”

According to the National Weather Service, “Hurricane Florence will be approaching the Carolina shores as the day progresses on Thursday. Although the exact timing, location, and eventual track of Florence isn't known, local impacts will likely begin in the afternoon hours and only worsen with time throughout the evening and overnight period.”

On Tuesday, Wilmington, North Carolina's National Weather Service took the warning even one step further, writing: "This will likely be the storm of a lifetime for portions of the Carolina coast, and that's saying a lot given the impacts we've seen from Hurricanes Diana, Hugo, Fran, Bonnie, Floyd, and Matthew. I can't emphasize enough the potential for unbelievable damage from wind, storm surge, and inland flooding with this storm.”

Gerst’s photos certainly drive that point home.
