With a broad range of user groups that range from the aviation community, to satellite programs, to general enthusiasts like pigeon racers and aurora watchers, SWPC’s web page offers each of these user groups a dashboard specific to the data sets and information that affects them.
The electric power grid, and consequently the power to your home and business, can be disrupted by space weather. One of the great discoveries of the 19th century was the realization that a time-varying magnetic field is able to produce an electrical current in a conducting wire. The basic idea is that the time rate of change of the magnetic flux (i.e. lines of magnetic force) passing through a current loop is proportional to the current that

NEAR-MISS CMEs ARE COMING: Geomagnetic unrest is possible on Dec. 17th when one or more CMEs pass close to Earth. The near misses will probably fall short of sparking a full-fledged geomagnetic storm. Nevertheless, auroras could fill the Arctic Circle when the CMEs pass by. CME impact alerts: SMS Text
POLAR STRATOSPHERIC CLOUDS AT NIGHT: When the Arctic night of Abisko, Sweden, fills with glowing color, it’s almost always the aurora borealis. Not so on the night of Dec. 12th. “The colors came from polar stratospheric clouds (PSCs),” reports Felix Feislachen, who photographed the “amazing” display:
ATMOSPHERIC RADIATION IS PLUMMETING: Cosmic rays in our atmosphere just hit a 10-year low. The sharp decline is shown in this dataset of more than 300 high-altitude balloon flights over California from 2015 to 2024:

THE POLAR VORTEX WOBBLED IN DECEMBER: Last month, sky watchers in Europe saw something rare and beautiful. A giant bank of polar stratospheric clouds (PSCs) escaped the Arctic Circle, and for more than a week they filled skies with rainbow color as far south as Italy. In the Italian comune of Sanfrè (latitude +45N), Pablo Javier Lucero was able to photograph the clouds at all hours of the day:

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
