GEOMAGNETIC ACTIVITY: Earth's magnetic field is reverberating from a CME impact during the early hours of Jan. 22nd. The hit compressed Earth's magnetic field, briefly exposing some geosynchronous satellites to solar wind plasma, and disturbed the ionization structure of Earth's upper atmosphere. As night falls on Jan. 22nd, Arctic sky watchers are reporting bright auroras in response to a polar geomagnetic storm (Kp=5). Please check http://spaceweather.com for images and updates.
STORM ALERTS: Would you like a call when geomagnetic storms are in progress? Storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

Strong Solar Activity Could Spark Auroras
Source - Space Weather News for Sept. 7, 2011: http://spaceweather.com
STRONG SOLAR ACTIVITY: On Sept. 6th, active sunspot 1283 produced two major eruptions including an impulsive X2-class solar flare. The blasts hurled a pair of coronal mass ejections (CMEs) toward Earth, which could spark geomagnetic activity when they arrive on Sept. 8-10.
High-latitude sky watchers should be alert for auroras in the nights ahead. Check http://spaceweather.com for images and updates.

Close Asteroid Flyby on June 27th
Source - Space Weather News for June 24, 2011:http://spaceweather.com
ASTEROID FLYBY: Newly-discovered asteroid 2011 MD will pass only 12,000 kilometers (7,500 miles) above Earth's surface on Monday, June 27th. NASA analysts say there is no chance the space rock will strike Earth. Nevertheless, the encounter is so close that Earth's gravity will sharply perturb the asteroid's trajectory. Details at http://spaceweather.com .
GEOMAGNETIC OUTLOOK: A fast-moving stream of solar wind is buffeting Earth's magnetic field. The combined effect of this stream plus a CME expected to arrive on June 24th has prompted NOAA forecasters to declare a ~30% chance of high-latitude geomagnetic storms during the next 24 hours. Storm alerts are available from Spaceweather.com in two forms: voice (http://spaceweatherphone.com) or text (http://spaceweathertext.com).

Electric-Blue Clouds Sighted over Europe
Source - Space Weather News for June 4, 2011: http://spaceweather.com
ELECTRIC-BLUE CLOUDS: The 2011 noctilucent cloud (NLC) season has begun. For the past few nights, observers in northern parts of Europe have spotted velvety, electric-blue tendrils rippling across the sunset sky. NLCs are a summertime phenomenon first reported by polar observers in the 19th century. In recent decades, for reasons no one fully understands, the clouds have intensified and spread as far south as Utah and Colorado. Visit today's edition of http://spaceweather.com for photos and observing tips.
CHANCE OF MAGNETIC ACTIVITY: NOAA forecasters estimate a 45% chance of geomagnetic activity on June 4th when an incoming solar wind stream and a CME might deliver a double blow to Earth's magnetic field. High-latitude sky watchers in both hemispheres should be alert for auroras.
