NEW SUNSPOTS: Magnetic fields are poking through the surface of the sun near the eastern limb, forming a pair of sunspots. At present these spots are almost-invisibly small, so solar activity should remain low.

MERCURY RISING: The most elusive of all planets, Mercury, is now visible in the evening sky. "It's only the second time in my life I have ever seen Mercury," says Jeffrey Beall who snapped this picture yesterday, looking west from his balcony in Denver, Colorado:

Mercury is the bright "star" just above the mountain ridge. The reason we seldom see Mercury is that it spends most of its time hidden by the glare of the sun. The weeks ahead are different: Mercury is moving away from the sun and becoming oh-so-temporarily easy to spot. Look for it tonight beaming through the rosy glow of sunset.

APOGEE MOON: If you think tonight's moon looks unusually small, you're right. The moon is at apogee, the point in its elliptical orbit farthest from Earth. Anthony Ayiomamitis of Athens, Greece, took a pair of photos to show how the apparent size of the moon changes from one end of its orbit (apogee) to the other (perigee):

It may be a trifle small, but it is still awfully pretty, as shown in these images from John Hacker at Prairie State Park in Barton County, Missouri; from Martin Wagner of Sonnenbuehl, Germany; from Joseph Shaw of Bozeman, Montana; and from Michel Hersen of Portland, Oregon.

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.

On 14 Feb 2006 there were 773 known Potentially
Hazardous Asteroids
