For 20 years he has been using the SABER instrument on NASA's TIMED satellite to monitor infrared emissions from "the thermosphere," the uppermost layer of the atmosphere. ![]() Mlynczak is an expert on the temperature up there. The extra heat has no effect on weather or climate at Earth's surface, but it's a big deal for satellites in low Earth orbit."Ībove: A severe geomagnetic storm on March 24, 2023, photographed by Michael Underwood from Yellowstone National Park "Increasing solar activity is heating the top of the atmosphere. "Blame the sun," says Martin Mlynczak of NASA Langley. Air surrounding our planet is now touching satellites in Earth orbit and dragging them down. A series of geomagnetic storms in 2023 has pumped terawatts of energy into Earth's upper atmosphere, helping to push its temperature and height to a 20-year high. If you're a satellite, this story is important. Earth-grazing Arietids are long, bright and beautiful. Sky watchers who want to see an Arietid are encouraged to look east during the dark hour just before dawn on Monday. The Arietids are a rare daytime meteor shower. ![]() It's a strong shower, but the meteors are difficult to see because the sun is up when the shower is most intense. The annual Arietid meteor shower peaks tomorrow, June 5th. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspots AR3319 and AR3323 have 'beta-gamma' magnetic fields that harbor energy for M-class solar flares.
