Weather Eye: Uncovering the Mystery of Ice Circles Times Online

The discovery of a 10-foot diameter "perfect circle of ice" on Devon's River Otter in England earlier this month leads to a discussion of other similar formations, particularly in North America. Columnist Paul Simons says, "Scientists...can find no signs of fakery in the ice circles, and they are stumped for a rational explanation." And, in another possibly natural but mysterious phenomenon, experts believe a bolide is the culprit for the Saturday evening Mystical Meteor That Lit Up Swedish Skies (there's video in Meteorite Vaporized Over South Sweden), and a Canadian professor says Fireballs Not as Rare as People Think.
