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

LYRID METEOR ALERT: The first significant meteor shower in months is about to begin. The annual Lyrid meteor shower peaks on the night of April 21-22 when Earth passes through a stream of debris from Comet Thatcher (C/1861 G1). These meteors are best seen from the northern hemisphere where the radiant is high in the sky before dawn: sky map.
THIS IS THE WORST TIME TO OBSERVE ‘THE DEVIL COMET’: If you get your science news from mainstream media, you might think this weekend is a great time to observe Comet 12P/Pons-Brooks, a.k.a. “The Devil Comet.” In fact, the opposite is true. The comet–barely a naked eye object on the best of nights–is almost completely overwhelmed by a combination of evening twilight and full Moonlight.
To illustrate the problem, Mike Olason photographed the comet sinking into the haze near of Tucson, Arizona, on April 20th:

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.
