Quadrantid Meteor Shower & SunSpots

Even though the meteor shower is passed read more information about what they learned from studying this event. And check out the solar cycle!--Have fun Homeschooling, Tabbi

METEOR SHOWER: Earth is about to pass through a stream of dusty debris from near-Earth asteroid 2003 EH1, producing the annual Quadrantid meteor shower. Forecasters expect a brief but intense peak of 50+ meteors per hour over Earth's northern hemisphere sometime between 0200 UTC and 0700 UTC on Friday morning, Jan. 4th. (Subtract 5 hours to convert UTC to EST.) The timing favors observers in the eastern USA, Europe and western parts of Asia. Winter storms frequently hide this shower from observers on the ground. To avoid such problems, a team of astronomers led by Peter Jenniskens of the SETI Institute plan to fly a plane above the clouds where they can train their cameras on the Quadrantids. Their data may reveal whether asteroid 2003 EH1 is the fragment of a broken-apart comet. Visit http://spaceweather.com for sky maps and more information.

JUST FOR FUN: This is a good time of year to see Orion the Hunter: the constellation rises in the east at sunset. Watching Orion ascend, you may experience the little-known "constellation illusion." The idea is the same as the Moon illusion; constellations viewed near the horizon look abnormally large. Go outside tonight and look. Can you believe your eyes?

Solar physicists have been waiting for the appearance of a reversed-polarity sunspot to signal the start of the next solar cycle. The wait is over. A magnetically reversed, high-latitude sunspot emerged today. This marks the beginning of Solar Cycle 24 and the first step toward a new solar maximum. Intense solar activity won't begin right away. Solar cycles usually take a few years to build from solar minimum (where we are now) to Solar Max (expected in 2011 or 2012). It's a slow journey, but we're on our way!
