Astronomers are scratching their heads over an unusual comet that is passing by the sun.  The icy visitor to the inner solar system does not belong to any known family of sungrazing comets, and it appeared to be doomed as it made its plunge toward the sun on Feb. 19th.  Instead of disintegrating, however, the comet has emerged apparently intact, and could become a target for telescopes on Earth when it emerges from the sun's glare in the weeks ahead.

SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids
Last night, Feb. 23-24, observers across the western half of North America witnessed a spectacular cluster of bright lights in the sky.  It was the re-entry and disintegration of a Chinese rocket body.  Coincidentally, a geomagnetic storm was in progress at the time and more than one photographer caught the rocket's debris cutting across curtains of Northern Lights.  Visit SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids for photos and more information.
DID YOU MISS THE STORM? On Feb. 23-24, auroras appeared over many northern-tier US States. Did you see them?  Subscribers to our Space Weather Alert Service were notified by phone while the storm was underway.  Sign up for alerts at  SpaceWeather Text (text) or Spaceweather PHONE (voice).

NOCTILUCENT CLOUDS: The strange behavior of noctilucent clouds over Antarctica in recent months has researchers on the trail of new teleconnections in Earth's atmosphere, which can alter weather and climate on a global scale. Visit SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids for the full story.
GEOMAGNETIC STORM:  A geomagnetic storm is underway on March 1st, and Arctic sky watchers are seeing bright auroras.  NOAA forecasters estimate a 60% chance of continued storming throughout the weekend.  Sign up for aurora alerts at SpaceWeather Text (text) or Spaceweather PHONE (voice).

Space Weather News for April 20, 2015

SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids
High-latitude sky watchers should be alert for auroras this week when a solar wind stream and a faint CME are expected to hit Earth's magnetic field in quick succession.  NOAA forecasters estimate a 45% to 65% chance of polar geomagnetic storms on April 21-22.
At the same time, Earth will be passing through a stream of debris from Comet Thatcher, source of the annual Lyrid meteor shower.  Sky watchers are already seeing a smattering of late-night fireballs as Earth approaches the diffuse core of the debris stream.  Meteor rates are expected to crest on April 22-23 with as many as 20 Lyrids per hour.

The Calbuco volcano in southern Chile erupted yesterday. Two blasts in 24 hours on April 22nd sent plumes of ash and sulfurous gas shooting at least 33,000 feet high. One of the eruptions occured at night and put on a spectacular display of rare and mysterious volcanic lightning.  Visit SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids for a picture of the lightning and a discussion of its underlying physics.
