Jupiter's Missing Stripe

Source - Space Weather News for Nov. 30, 2010: http://spaceweather.com

JUPITER'S MISSING STRIPE: A disturbance in Jupiter's atmosphere thought to herald the return of the planet's missing stripe is growing rapidly and now stretches almost halfway around Jupiter's globe. It is so big, novice observers are beginning to notice it in the eyepieces of backyard telescopes. Visit http://spaceweather.com for latest images and a sky map.

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.

The Sun Steals Comets from Other Stars

Some of the comets in our Solar System probably came from other stars, according to new research by NASA-supported scientists. Studying these 'alien' comets, they say, could reveal new information about stellar systems far, far away.

Jupiter's Missing Stripe, Returning?

Source - Space Weather News for Nov. 11, 2010: http://spaceweather.com

JUPITER'S MISSING STRIPE, RETURNING? Earlier this year when Jupiter's great South Equatorial Belt (SEB) vanished, researchers urged amateur astronomers to be alert for its eventual return. The SEB had come and gone before, they noted, and the revival was something to behold. Alert: It might be happening now. An energetic white plume is rising above Jupiter's cloudtops, possibly heralding the return of the giant planet's missing stripe. Visit http://spaceweather.com for images and updates.

Possible Comet Outburst in Progress

Source - Space Weather News for Nov. 8, 2010: http://spaceweather.com

POSSIBLE COMET OUTBURST: A comet discovered just a few days ago by amateur astronomers in Japan is gliding by Saturn in the pre-dawn sky. Comet Ikeya-Murakami (C/2010 V1) is not visible to the unaided eye, but observers say it is a fairly easy target for backyard telescopes. Images obtained over the weekend reveal what appears to be an outburst in progress. The comet's coma (atmosphere) bears a striking resemblance to the coma of Comet Holmes, which famously exploded in 2007. Check http://spaceweather.com for photos and more information.

SOLAR ACTIVITY UPDATE: After unleashing one of the brightest X-ray flares in years on Saturday afternoon, Nov. 6th, sunspot 1121 took Sunday off. No strong flares were recorded for the rest of the weekend. Nevertheless, the active region's magnetic field is complex and harbors energy for more eruptions. NOAA forecasters estimate an 85% chance of M-flares during the next 24 hours.

Bright X-ray Solar Flare

Source - Space Weather News for Nov. 6, 2010: http://spaceweather.com

BRIGHT SOLAR FLARE: Active sunspot 1121 has just unleashed one of the brightest x-ray solar flares in several years, an M5.4-class eruption at 15:36 UT on Nov. 6th. Radiation from the flare created a wave of ionization in Earth's upper atmosphere that altered the propagation of low-frequency radio waves. There was, however, no bright CME (plasma cloud) hurled in our direction, so the event is unlikely to produce auroras in the nights ahead. Visit http://spaceweather.com for a movie of the eruption and more information about this increasingly active sunspot.

Farside Solar Flares

Source - Space Weather News for Nov. 3, 2010: http://spaceweather.com

FARSIDE SOLAR FLARES: An active region just over the sun's eastern horizon is crackling with solar flares and hurling material high above the stellar surface. One of today's flares, a C4-class event, created a wave of ionization in Earth's upper atmosphere despite the fact that the blast site was not directly visible from Earth. The source of this activity appears to be old sunspot 1112, which has spent the last ~12 days transiting the far side of the sun, and is now about to turn back toward our planet. Visit http://spaceweather.com for movies of today's activity and updates.

COMET HARTLEY UPDATE: NASA's Deep Impact (EPOXI) probe is closing in on Comet Hartley 2 for a daring flyby on Nov. 4th. The small but active comet is full of surprises, with spinning jets, geysers of cyanide gas, and a strangely pickle-shaped core. Mission scientists expect to reveal first images from the flyby during a press conference on Thursday afternoon, around 4 pm EDT. Tune into NASA TV to follow events live, and meanwhile read this story for a preview:
