Unusual Radar Echoes Detected as Noctilucent Clouds Intensify


Source - Space Weather News for May 28, 2015: http://spaceweather.com

Last week, Earth-orbiting satellites detected the first noctilucent clouds of the 2015 season.  Now people on Earth are seeing them, too.  Photographers in Scotland recorded a fairly bright display of the electric-blue clouds on May 28th.  At the same time, radars have detected intense echoes coming from the "noctilucent zone" 80 km to 90 km above Earth's surface--possibly coming from the clouds themselves.

Close Encounter with Jupiter

JUPITER AT ITS BEST: Tonight, Sept. 20-21, Earth and Jupiter converge for their closest encounter in decades. The giant planet will soar across the sky at midnight, outshining everything except the Moon itself. Although big, bright Jupiter will remain close to Earth for weeks to come, tonight is the closest of all. Check http://spaceweather.com for images and more information.

SPACE STATION RADAR ECHO: Over the weekend, the International Space Station flew through the radar beam of the US Air Force Space Surveillance System in Texas. The echo was strong enough to be heard by amateur radio operators across the southern USA. A sample echo is highlighted on today's edition of http://spaceweather.com .

Arietid Meteor Shower this Weekend

Source - Space Weather News for June 5, 2009: http://spaceweather.com

DAYTIME METEORS: The annual Arietid meteor shower peaks on Sunday, June 7th. The Arietids are unusual because they are daytime meteors; they stream out of a point in the sky not far from the sun. The best time to look is just before dawn on Sunday morning when it may be possible to spot a small number of Arietids skimming the top of Earth's atmosphere. Such "Earthgrazing" meteors tend to be long, colorful, and very pretty. After daybreak, when the meteors are no longer visible to the human eye, you can listen to radar echoes from the Arietids by tuning in to our online meteor radar: http://spaceweatherradio.com .

"The Arietids are the strongest daylight shower of the year," notes Bob Lunsford of the American Meteor Society. "If you could see them through the sun's glare, you would count as many as 60 per hour. Also, don't forget that the daytime Zeta Perseids peak only two days later and are considered the second strongest daylight shower. In all my years of viewing I have never seen a Zeta Perseid, but I have seen a few Arietids. They have all been Earthgrazers and very impressive meteors."
