Will I keep the planet positions current?
I kinda doubt it, but if not, here is the sky watch link:

June 23, 2010 - Jupiter is a long way away (meaning close to the sun from our perspective) and seen rising in the morning sky before dawn. Saturn was in full opposition in March. From our perspective it is heading for the sun (actually the Earth is working its way around and away from Saturn) and can be seen in the southwest after sundown. Mars is also seen in the west after sundown. Venus is currently the "evening star".

Weekend Under the Stars

We went once -- many years ago. We learned the first rule very quickly: Do NOT show up after dark unless you are wearing night-vision goggles and driving with your lights off. We were told by our astronomer friend to bring red-light flashlights. At least we did that. After we were done blinding ourselves and everyone else, we settled in and adjusted to the night. For the first time in my life, I saw the Milky Way. There is a chance that you have never seen it. It is a cloud that is not a cloud. Finding those familiar constellations I am used to...Forget it! There were too many stars!
What made the sky so amazing is the total absence of "light pollution". Even distant farm lights can block out many weaker stars. Of course, these parties are scheduled during new moons also. I brought my small refractor telescope which is a great moon and planet scope but I wasn't very good at nebula and galaxy hunting like some of these people. The fun was in walking around (the sky lit the ground enough to see silhouettes), meeting people, and checking out a few giant reflector telescopes. One of them had a step ladder needed to reach the eye piece. Nearly all needed to be on precision motors to adjust for the Earth's rotation. The best part was without the telescopes, though. A few people had charts of the lower man-made satellites so that we could watch for them coming up from the west. Jacki just loved laying down, looking at the crowded sky, and finally taking the time to see the Earth turn. We plan to be there this summer to once again enter the wonderful, geeky world of amature astronomy!

A Moon Phase Quiz Question

This may be simple for some but most people don't think much about it. Here is the question:
You are looking to the west, admiring the sunset. A little higher in the western sky, you see a crescent moon. Is it waxing (heading for full moon) or waning (heading for new moon)? ...Or is there a way of telling?
Click here (or scroll down) for a hint.























Big hint: The Moon orbits the Earth in the same direction as the Earth spins. If the sun goes down in the west, what direction do you think you are heading? Same direction the moon is heading -- away from the sun. Does that answer it? Here is a picture from good old MS Paint (still beats KolourPaint -- too bad) and my handy-dandy mouse that I hope explains it.

It is waxing
It is heading for full. Along the same lines... Before a lunar eclipse happens, where can you tell people the shadow will start, the bottom or the top? Back to
