STEVE is smearing green 'streaks' across the sky, and nobody knows why
It can appear closer to the equator than a typical aurora, and is often accompanied by a "picket fence" of jagged green points dancing beside it. Nobody knows what causes STEVE, but scientists agree it's no mere aurora. These tiny smears of green light are sometimes seen extending horizontally from the bottom of STEVE's green fence pickets, curving backward for about 20 to 30 seconds before vanishing from view. That makes the streaks "the lowest‐altitude and smallest‐scale optical feature associated with STEVE," the researchers wrote in the study. One clue about the streaks' origins comes from their green color, which is identical to the color of STEVE’s picket fence.space.com
NASA launches new ICON satellite
SAN ANTONIO - As satellite communications become vital for tasks on Earth, like landing planes and controlling self-driving cars, the National Aeronautics and Space Administration has launched a new satellite with the hope of better understanding space weather. "It will go up into the Earth's very uppermost atmosphere to measure a type of weather called space weather," said NASA scientist Sarah Jones. Weather Tool: KSAT's new weather app is a hyperlocal, easy-to-use tool for San Antonio, beyondThe upper atmosphere is a battleground of sorts, where Earth's weather interacts with outer space's solar radiation. Latest weather forecast: More temperature, humidity swings this week"It affects our technology. NASA hopes the result is an ability to better forecast space weather.
