Tornadoes on the Sun!
News story originally written on May 1, 1998

There just seem to be so many exciting things happening in space these days (and for the last year in fact!). One new discovery is that there are storms on the Sun very similar to our own tornadoes! This discovery was made by ESA/NASA spacecraft SOHO.

SOHO has spotted a dozen of these gyrating storms so far. It seems they occur most frequently at the poles of the Sun. These storms are as wide as the whole of planet Earth and have gusts ten times faster than anything measured on Earth! Doesn't seem as if we're in Kansas anymore!

Also, happening on the Sun...There seems to have been a coronal mass ejection two days ago. X-ray fluxes at Earth have been extremely high. Activity like this on the Sun can often disrupt radio communications. It can cause pilots to lose contact with their control towers and even disorient migratory anmals that depend on the Earth's magnetic field for guidance. The space weather forecast for the next few days is unsettled to active.
