Magnetic Storm on Comet Lovejoy?
Source - Space Weather News for Jan. 9, 2014: http://spaceweather.com
MAGNETIC STORM ON A COMET? Everyone knows about geomagnetic storms on Earth. But did you know that comets can have them, too? Right now, a type of magnetic storm may be in progress in the tail of bright Comet Lovejoy (C/2014 Q2), causing "plasma blobs" and "disconnection events" visible in amateur telescopes. Visit http://spaceweather.com for images and more information.
GEOMAGNETIC STORM ALERTS: A strong geomagnetic storm on Jan. 7th took forecasters by surprise. Subscribers to our Space Weather Alert Service were notified while the storm was in progress.

Geomagnetic Storm and Naked-eye Comet
Source - Space Weather News for Dec. 29, 2014: http://spaceweather.com
GEOMAGNETIC STORM: The year is ending with an outbreak of auroras. Sky watchers around the Arctic Circle are seeing bright Northern Lights as Earth enters a stream of high-speed solar wind, causing G1-class storm conditions on Dec. 29th.

BRIGHTENING COMET: The "Christmas Comet" C/2014 Q2 (Lovejoy) has continued to brighten, and now observers around the world are reporting seeing it with the unaided eye from dark-sky sites. Comet Lovejoy is a fine target for backyard telescopes, as shown on today's edition of http://spaceweather.com

Bright Comet Dives into Solar Radiation Storm
INCOMING CME: Sunspot AR1429 unleashed another strong flare (category M7.9) on March 13th. The explosion produced a significant coronal mass ejection (CME), which forecasters say should reach Earth on March 15th. Geomagnetic storms are possible when the cloud arrives. Check http://spaceweather.com for updates.
SUNDIVING COMET: A bright comet related to sungrazing Comet Lovejoy is diving into the sun. The orbiting Solar and Heliospheric Observatory (SOHO) is monitoring the comet's death plunge even as the sun peppers the spacecraft with energetic particles accelerated by the March 13th solar flare. Images of the comet are featured on today's edition of http://spaceweather.com.

Space Station Commander Captures Unprecedented View of Comet
International Space Station Commander Dan Burbank captured spectacular imagery of Comet Lovejoy as seen from about 240 miles above the Earth's horizon on Wednesday, Dec. 21.
Sungrazing Comet Lovejoy Photographed from Earth Orbit
Astronauts onboard the International Space Station have seen sungrazing Comet Lovejoy from Earth orbit. ISS commander Dan Burbank describes the comet's green-glowing tail as "the most amazing thing I have ever seen in space." Video from the ISS and updated images from Earth are highlighted on today's edition of Spaceweather.com.

Comet Lovejoy at Sunrise
SUNRISE COMET: Comet Lovejoy is receding from the sun, remarkably still intact after its Dec. 16th plunge through the solar atmosphere. Multiple observers in the southern hemisphere are now reporting that they can see and photograph the comet's tail shining through the twilight of sunrise. Pictures of this rare apparition are highlighted on today's edition of http://spaceweather.com.

Comet Lovejoy Plunges into the Sun ... and Survives
Sungrazing Comet Lovejoy has shocked astronomers by surviving its "death plunge" into the sun. Must-see movies of the comet's passage through the sun's atmosphere are featured in today's story from Science@NASA.

Comet Lovejoy Survives Death-Plunge into the Sun
SUNGRAZING COMET SURVIVES: Sungrazing Comet Lovejoy has confounded the experts and survived its close encounter with the sun. Last night, NASA's Solar Dynamics Observatory recorded amazing movies of the comet entering and exiting the sun's atmosphere. Comet Lovejoy's scorched remnant is now receding from the sun in full view of the Solar and Heliospheric Observatory. Visit http://spaceweather.com for the latest movies and discussion.

Spectacular Sundiving Comet
SUNDIVING COMET: Comet Lovejoy is plunging toward the sun, and its ~200-meter wide core is vaporizing furiously as it approaches the hot star. So far the comet's brightness seems to be exceeding expectations. Indeed, there is a slim chance that the sundiver will brighten enough to be seen with the naked eye in broad daylight on Dec. 15th. Check http://spaceweather.com for further discussion and the latest movies from the Solar and Heliospheric Observatory.
