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 Perseid Meteor Shower is Underway
Source - Space Weather News for August 11, 2012: http://spaceweather.com
PERSEID METEOR SHOWER: Earth is entering a stream of debris from Comet Swift-Tuttle, source of the annual Perseid meteor shower. Worldwide observers are now reporting more than 30 Perseids per hour, a number that could triple during the weekend when Earth reaches the heart of the debris zone. Forecasters recommend looking during the dark hours before dawn, especially Sunday morning, August 12th, when activity is expected to be highest. Visit http://spaceweather.com for sky maps, observing tips, and links to a live meteor radar.

Big Picture Science for 05/21/12 - To Earth and Back
Big Picture Science - To Earth and Back
We are all Martians … or could be, if, billions of years ago, Red Plant microbes fell to Earth and eventually evolved to us. Okay, that one’s a big “if.” But microbes can survive space travel. Meet the NASA officer whose task is to keep Earth, Mars – and the entire solar system –safe from hitchhiking bacteria.
And, even if we’re not Martians (darn!), did life once thrive on the Red Planet … and does it still today?
Plus, why meteorites may be happy habitats for life.
Guests:
- Catharine Conley – NASA planetary protection officer
- Chris McKay – Planetary scientist, NASA Ames Research Center
- Paul Davies – Director of the BEYOND: Center for Fundamental Concepts in Science at Arizona State University
- Aaron Burton – Astrobiologist, NASA Goddard Spaceflight Center
- Debbie Kolyer – Grants Manager, SETI Institute

Meteor Shower and Super Moon
Source - Space Weather News for May 3, 2012: http://spaceweather.com
Earth is entering a stream of debris from Halley's Comet, source of the annual eta Aquarid meteor shower. The shower peaks this weekend on May 5th and 6th.
Glare from a perigee full Moon--a "Super Moon"--will interfere with the display. Nevertheless, observers especially in the southern hemisphere could still see dozens of meteors during the hours before local sunrise on May 6th.
More information about the shower and live audio from a meteor radar may be found on http://spaceweather.com

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.

Meteors from Halley's Comet
Source - Space Weather News for May 4, 2009: http://spaceweather.com
METEOR SHOWER: Earth is entering a stream of dusty debris from Halley's Comet, the source of the annual eta Aquarid meteor shower. Forecasters expect the shower to peak on Wednesday, May 6th, with as many as 85 meteors per hour over the southern hemisphere. Rates in the northern hemisphere will be less, 20 to 30 per hour. The best time to look is during the dark hour before local sunrise on Wednesday morning. Visit http://spaceweather.com for sky maps and details.

Solstice Meteor Shower
Source - Space Weather News for Dec. 21, 2008: http://spaceweather.com
URSID METEORS: Earth is passing through a stream of debris from comet 8P/Tuttle and this is causing the annual Ursid meteor shower. Forecasters expect the Ursids to peak on Dec. 22nd with 8 to 10 meteors per hour flying out of the constellation Ursa Minor (the Little Dipper) not far from the north star. The display is usually mild, but outbursts of Ursids occasionally surprise observers with rates many times normal. The last time this happened was in 2006.
Standing outdoors to watch Ursids in December can be a chilling experience. So why not stay inside and listen? Spaceweather.com is broadcasting live audio from the Air Force Space Surveillance Radar in Texas. When a meteor passes over the facility--"ping"--there is an echo. Because the Ursid radiant is circumpolar (always up) over the radar, the echoes may be heard at any hour, night or day. Tune in to http://spaceweather.com to try the audio feed, which can support 1000 simultaneous listeners.
UNIQUE CHRISTMAS GIFT: For less than the cost of a night at the movies, you can give someone the heavens for Christmas. Send them a gift subscription to Spaceweather PHONE: http://spaceweatherphone.com
