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.

Comet Lovejoy Survives Death-Plunge into the Sun
Source - Space Weather News for Dec. 16, 2011: http://spaceweather.com
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.

Double Blast on the Sun
Source - Space Weather News for Jan. 28, 2011: http://spaceweather.com
DOUBLE BLAST: This morning, a spectacular double eruption on the sun produced the strongest solar flare of the year so far (an M1-class event). Plasma clouds produced by the event are expected to miss Earth, so no geomagnetic storms are in the offing. Today's edition of http://spaceweather.com highlights movies captured by SOHO and the Solar Dynamics Observatory.
STRANGE LIGHT PILLARS: A photographer has recorded extraordinary pillars of light shooting into the night sky from a corn mill in Nebraska. The tall luminous columns were capped with nested V-shaped tops that distinguish them from ordinary urban light pillars. Check http://spaceweather.com for must-see photos and an explanation of the icy phenomenon.

Strong Solar Farside Activity
Source - Space Weather News for Nov. 26, 2010: http://spaceweather.com
SOLAR FARSIDE ACTIVITY: The Earth-facing side of the sun is relatively quiet, but the farside is alive with activity. On Nov. 26th, NASA's twin STEREO spacecraft and the Solar and Heliospheric Observatory (SOHO) observed eruptions from multiple farside blast sites. Visit http://spaceweather.com to view movies of these events and for more information about when the active regions might turn to face Earth.
RADAR MOON: Earlier this week, the Moon passed through the beam of the US Air Force Space Surveillance Radar in Texas. An electrical engineer in Georgia recorded the echo and made a simple image of the Moon based on the reflection. Sights and sounds of the "radar Moon" are featured on today's edition of http://spaceweather.com.

A Comet Plunges toward the Sun
Source - Space Weather News for Oct. 20, 2010: http://spaceweather.com
SUNDIVING COMET: A newly-discovered comet is plunging toward the sun for a close encounter it probably will not survive. The comet is too deep in the sun's glare for human eyes to pick out, but it is showing up nicely in coronagraph images from the Solar and Heliospheric Observatory. Visit http://spaceweather.com for latest movies.
ORIONID METEOR SHOWER: Earth is passing through a stream of debris from Halley's Comet, and this is causing the annual Orionid meteor shower. Bright moonlight is reducing the number of visible meteors; nevertheless, sky watchers are reporting some bright Orionids. The best time to look is during the hours before local dawn on Thursday, Oct. 21st, and again on Friday, Oct. 22nd. Check http://spaceweather.com for a sky map and more information.
SPACE WEATHER ALERTS: With the arrival of northern autumn, aurora season is underway. Would you like a call when geomagnetic storms erupt at your latitude? Sign up for Space Weather Phone: http://spaceweatherphone.com

Incoming CME could spark high-latitude auroras
Source - Space Weather News for August 9, 2010: http://spaceweather.com
INCOMING CME: The solar eruption of August 7th might affect Earth after all. Newly-arriving data from the Solar and Heliospheric Observatory (SOHO) show a CME heading our way with a significant Earth-directed component. High-latitude sky watchers should be alert for auroras when the cloud arrives on August 10th. A movie of the CME is featured on today's edition of http://spaceweather.com.
EARLY PERSEID METEORS: The Perseid meteor shower doesn't peak until August 12th, but already late-night sky watchers are seeing a nice display of shooting stars. Observers are counting as many as 20 Perseids per hour from dark sky sites, a number that could increase 3- to 5-fold before the week is over. Visit http://spaceweather.com for more information.

Sungrazing Comet Approaches Sun
Source - Space Weather News for Jan. 2, 2009: http://spaceweather.com
SUNGRAZING COMET: Today, a bright comet is approaching the sun for a perilous close encounter, and it probably will not survive. The comet was discovered by an amateur astronomer monitoring images from NASA's STEREO-A spacecraft. The Solar and Heliospheric Observatory (SOHO) has a good view of the comet's approach and images are being posted on http://spaceweather.com.
FLYBY ALERT: The International Space Station is about to begin a series of bright flybys over North America. Your iPhone or iPod Touch can help you see the behemoth spacecraft when it passes overhead in the night sky. Visit http://simpleflybys.com for information about our newest app.
FIRST METEORS OF 2010: The annual Quadrantid meteor shower peaks on Jan. 3rd around 1900 UT (2 p.m. EST) when Earth passes through a stream of debris from shattered comet 2003 EH1. The timing of this northern shower favors observers in eastern Europe and Asia. Bright moonlight will interfere with the display, which can reach 100+ meteors per hour under ideal conditions.

NASA's Greatest Mission, and Volcanic Cloud Update
Source - Space Weather News for April 7, 2009: http://spaceweather.com
NASA's GREATEST MISSION? The Solar and Heliospheric Observatory (SOHO) has reached the final round of NASA's Mission Madness tournament where it is competing against upstart SPB, the Super Pressure Balloon, for the title "NASA's Greatest Mission." We endorse SOHO. Since the observatory was launched more than 13 years ago, it has revolutionized solar physics and the art of space weather forecasting--and the plucky spacecraft is still going strong. Vote now and help propel a spaceweather favorite to the championship: http://mission-madness.nasa.gov/
VOLCANIC CLOUD UPDATE: Sulfur dioxide emissions from Alaska's Mt. Redoubt volcano are spreading. A doughnut-shaped cloud about 600 miles wide is now swirling through the stratosphere off the coast of California. Sulfur dioxide and associated aerosols have been known to produce sunsets of exceptional beauty. Check spaceweather.com for the latest sulfur dioxide maps to see if you should be looking for volcanic colors this evening: http://spaceweather.com.
