Space Weather News for 28 July 2002
http://www.spaceweather.com
The Boulder sunspot number reached its highest value in more than a year
this weekend; the sun is peppered with spots. On Friday, an explosion
near one of them--giant sunspot 39--hurled a coronal mass ejection (CME)
into space. Although the CME was not squarely Earth-directed, some of the
cloud is heading our way. It could sweep past Earth as early as Sunday,
July 28th, and trigger geomagnetic activity. Sky watchers should be alert
for auroras after nightfall. Visit SpaceWeather.com for more information
and updates.
