Leonids Rain in Spain
Space Science News home
"We observed many, many, many Leonids falling from the sky," said Casper ter Kuile of the Dutch Meteor Society, who was working with a team of observers located between Valencia and Alicante in Spain. "Our experienced visual observers counted about 30 Leonids per minute!"

The high rate noted by observers in Spain, over 1800 meteors per hour, was substantially greater than the 500 to 1000 per hour that most experts had predicted. The storm was even more intense over parts of the Middle East, where members of the Israeli Astronomical Association recorded 70 meteors per minute for just over a half an hour. Like other global observers, the Israeli team was struck by the abundance of faint meteors and the relative absence of bright fireballs. Preliminary reports by meteor watchers in the Canary Islands and near the Gorges du Verdon in France confirm this general picture of the outburst.
The meteor storm was not seen west of the Atlantic. In North America sky watchers saw relatively few Leonids -- at most 40 to 50 per hour. The majority of these were fast-moving and dim.

Preliminary data from their observing campaign show a sharp peak in meteor activity just after 200 UT on November 18. [more] Web Links
