When I was a kid my dad and I participated in an astronomy course offered at the local Franciscan college - St. Francis College. We lived about a mile from the planetarium and probably spent six weeks learning about the stars. Everything I know about starts I remember from that class.
Yesterday my Dad, Mack, sent me the following cut and paste piece that made viewing the night sky last night a real treat. Even from downtown Washington, DC you could see this. It was pretty amazing! Don’t worry. Tonight will be nearly as good so plan on checking it out!
Every once in a while, something will appear in the night sky that will attract the attention of even those who normally don’t bother looking up. It’s likely to be that way on Monday evening, Dec. 1.
Venus has adorned the southwestern twilight sky since late August. No other star or planet can come close to matching Venus in brilliance. During World War II, aircraft spotters sometimes mistook Venus for an enemy airplane. There were even cases in which Venus drew antiaircraft fire.
This winter, Venus is the unrivaled evening star that will soar from excellent to magnificent prominence in the southwest at nightfall. The interval by which it follows the Sun will increase from nearly three hours on Dec. 1 to almost four hours by Jan. 1. It’s probably the first “star” you’ll see coming out after sunset. In fact, if the air is very clear and the sky a good, deep blue, try looking for Venus shortly before sunset.
Jupiter starts December just above Venus and is moving in the opposite direction, dropping progressively lower each evening. By month’s end Jupiter meets up with another planet – Mercury – but by then Jupiter is also descending deep into the glow of sunset. In January, Jupiter will be too close to the Sun to see; it’s in conjunction with the Sun on Jan. 24.
Earthlit Ball
A very close conjunction of the crescent moon and a bright star or planet can be an awe-inspiring naked-eye spectacle. The English poet, critic and philosopher, Samuel Taylor Coleridge (1772-1834) used just such a celestial sight as an ominous portent in his epic, “The Rime of the Ancient Mariner.” In addition, there are juxtaposed crescent moon and star symbols that have appeared on the flags of many nations, including Turkey, Pakistan, Malaysia, Algeria, Mauritania, and Tunisia.
Also on Monday evening, you may be able to see the full globe of the moon, its darkened portion glowing with a bluish-gray hue interposed between the sunlit crescent and not much darker sky. This vision is sometimes called “the old moon in the young moon’s arms.” Leonardo da Vinci (1452-1519) was the first to recognize it as what we now call “earthshine.”
As seen from the moon, the Earth would loom in the sky some 3.7 times larger than the moon does for us. In addition, the land masses, the oceans and clouds make the Earth a far better reflector of sunlight as compared to the moon. In fact, the Earth’s reflectivity varies as clouds, which appear far more brilliant than the land and seas, cover greater or lesser parts of the visible hemisphere. The result is that the Earth shines between 45 and 100 times more brightly than the moon.
The Earth also goes through phases, just as the moon does for us, although they are opposite from what we see from Earth. The term for this is called “complementary phases.” On Nov. 27, for example, there was a new moon for us, but as seen from the surface of the moon that day, there appeared in the lunar sky a brilliant full Earth. A few nights later, as the sliver of a crescent moon begins to appear in our western twilight sky, its entire globe may be glimpsed
Portsmouth, R.I. (December 1, 2008) – US SAILING announced today that The Racing Rules of Sailing 2009-2012 including US SAILING prescriptions is now available, in time before the new rules become effective on January 1, 2009. Current members of US SAILING will soon receive a free copy of the new rulebook and additional copies are available for purchase through US SAILING’s online store (at discounted rates for US SAILING members). Dave Perry’s Understanding the Racing Rules of Sailing Through 2012 - a companion to The Racing Rules of Sailing - is also now available through US SAILING’s online store.
Dag nab the rules. You know, I’ve been accused of spending too much time reading the Racing Rules, but today I proved that you can never have quite enough grip of the ole rules.
I race in Annapolis every Sunday. So far this year our weather has been pretty nice. Maybe a little chilly, but all in all it has been pretty nice. Tomorrow… well it is supposed to be pretty nasty. Wet and cold. Maybe even wet cold and windy! Here is what NOAA says:
This is the first of several posts about racing in any “beer can” or winter frostbite series. Beer can races are often mixed fleet events hosted by local clubs. They get their moniker “beer cans” because most often RC’s use existing government marks in order to set the courses. Then again, if you check the bilges of many boats racing in these series you might get another impression all together.

So early registration for the 2009 Marblehead to Halifax Race opened up today. If you scroll back into the archives of this blog you’ll find posts from the last time I entered this race. It was ill fated, but a great experience.
