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.
