CELESTIAL HIGHLIGHTS IN 2008
A TOTAL ECLIPSE OF THE MOON ON FEBRUARY 20TH -- The midwinter Full Moon will become totally immersed in the shadow of the Earth during the late evening hours of February 20th. On that Wednesday night, the Moon will begin to enter the Earth's dark umbral shadow at 8:43 p.m. Eastern Standard Time. The total phase of the eclipse will last for 50-minutes and will run from 10:01 to 10:51 p.m. EST. The Moon will then begin emerging from the dark shadow, and will be completely free of it by 12:09 a.m. EST on Thursday morning, February 21st. North and South Americans will have a ringside seat for this event. The entire eclipse will be visible for the eastern two-thirds of the United States and all of South America. Along the immediate West Coast of the U.S. and Canada, the Moon will be entering the umbra as it rises. The Moon will pass through the southern portion of the Earth's shadow, which means its lower limb will probably glow orange or red, while the upper part of the Moon should be shaded with a dark gray or chocolate hue. AS A BONUS, at mid-eclipse (10:26 p.m. EST) the Moon will form a strikingly broad triangle with the bright star Regulus (to the Moon's upper right) and the planet Saturn (to the Moon's upper left).
METEOR SHOWERS IN 2008 -- The annual performance of the Perseid Meteors (or St. Laurence's Tears) is due late on Monday night, August 11th into the early hours of Tuesday, the 12th. These meteors appear to fan out from a spot in the sky between the constellations Perseus (hence the name "Perseid") and the "W" of Cassiopeia. Although the Moon will be at an unfavorably bright waxing gibbous phase, it is due to set at around 1:30 a.m. local time on the morning of the 12th, leaving the rest of the predawn hours dark for meteor observing. Typically, the Perseids appear as swift streaks of light, darting from out of the northeast sky, chiefly after midnight. Some are faint . . . quite a few are bright . . . and occasionally a fireball will blaze forth and light up the sky. Usually they are yellowish in color, fewer white, the brightest ones are bluish-green. About a third of all the meteors seen leave vapor trains, a few of which which may be spectacular and last for many seconds. Some end in flares or bursts. From dark-sky locations anywhere from 45 to 90 meteors per hour may be sighted and the display can be seen, but in noticeably lesser numbers for 2 or 3 days before and after the peak night.
The Geminid Meteors will peak during the night of December 13-14 (Saturday night/Sunday morning). Unfortunately, 2008 is not a favorable year for this display because the Moon will turn full on December 12th and will light up the sky and probably obscure many of the fainter streaks. This shower is an all-night affair; the meteors radiate from near the bright star Castor in the constellation Gemini, which rises from the east-northeast after about 6 in the evening and is almost directly overhead by 2 a.m. Most appear white; some are yellow and a few blue, orange and even red. These meteors move about half as fast as the Perseids and thus seem to move across the sky in a more majectic fashion. From dark sky locations, as many as 60-120 meteors per hour may be counted. They're at on-quarter peak strength for a day or two before and after the peak. Faint meteors predominate up until the peak, then much brighter meteors and even some fireballs are seen thereafter. The parent body of this rich stream was long undiscovered; is the asteriod 3200 Phaethon, now considered to be the denuded core of the Geminid comet.
