Space Weather News for Sept. 19, 2003

HURRICANE HALOS: As Hurricane Isabel advanced on North America yesterday sky watchers in New England saw some unusually vivid "halos and dogs" around the Sun. Clouds on the leading edge of storm fronts often produce such effects--and they were much in evidence ahead of Isabel. Visit for photos.

PLANETARY RINGS: If you happen to be awake before sunrise on Saturday, Sept. 20th, step outside and look up. Saturn and the fat crescent moon will be pleasingly close together in the middle of the constellation Gemini. Even a small telescope will reveal Saturn's magnificent rings.

SOLAR WIND: Earth is inside a high-speed solar wind stream flowing from a coronal hole on the sun. Northern Lights have appeared as far south as Michigan this week. More auroras are possible this weekend, especially at high latitudes.

Visit for more information, photos and sky maps.
