REINDEER AND AURORAL SPIKES: A solar wind stream hit Earth's magnetic field on Feb. 9th, causing a G1-class geomagnetic storm. Petr Horálek and more than a dozen reindeer watched the light show from Kilpisjärvi, Finland:

Daily monitoring of solar flares, geomagnetic storms, Earth's aurora, and all forms of space weather.

Sep 24, 2024 · SPACE WEATHER BALLOON DATA: Almost once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface.

The auroras on this page were triggered by a coronal mass ejection hitting Earth on Oct. 29th. The CME was hurled into space by one of the most powerful solar explosions in years--an X17-class flare from giant sunspot 486. See also the September 2003 aurora gallery.

Near Earth Asteroids or Potentially Hazardous Asteroids 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.
