TRANSIT OF MERCURY: On Monday morning, May 9th, Mercury will pass directly between Earth and the sun, producing a rare transit visible from the Americas, Europe, Africa and parts of Asia.  Visit Spaceweather.com for observing tips and links to live webcasts.

CHANCE OF STORMS: NOAA forecasters say there is a 65% chance of G1-class geomagnetic storms on May 9th when Earth enters a solar wind stream filled with negative-polarity magnetic fields. A display of high-latitude auroras is possible, especially in the southern hemisphere where visibility is improved by darkening autumn skies.
