I don't plan to photograph the eclipse much, the recommendation I've heard is to enjoy the spectacle and let the pros take the photos and video. However, if you want to photograph, do some research so you don't waste your time. Here's one article...
What a great topic astronomy is. I hope you become as excited about learning this as I am. Please spend some dark clear night just staring at the stars and thinking about 13.7 billion years since the Big Bang and 46 billion light years to the edge of the universe and the FACT that you are made of elements forged in stars that died billions of years ago!
This is our class website. Please look at it at least weekly to see assignments, advice, reminders, clues, cartoons, and notices. You should check here before you start HW in case I've made changes or offered clues. This site is not locked, so your parents and guardians are encouraged to see what you are doing. Please give them the link.
If you are not likely to remember to check here every 3-4 days, then you should subscribe so you'll get an email when I update it.
HW Wednesday: simple quiz on chapter 0 will be given, know the major points.
HW Friday: chapter 0 Conceptual Self Test 1, 8, 9
HW Next Tue: Take a picture of the moon, and note its phase. Figure a way to print it or bring your camera to class on Monday. If you have a good camera with a telephoto lens, please use that. Also, post a 100-150-word blog on an article in Astronomy Magazine from the library. Be prepared to talk about it in class. See my example under News Forum at top. Start thursday to check that you have access to post. You'll need to sign in. Click on the Astroblog link above and look at Lauren Casson's entry for a good example http://ismscience.org/moodle/mod/forum/discuss.php?d=444.
NOTE: IF YOU MISS CLASS, you can find the lecture slides posted above. This is only part of the presented material, of course. Check with other students for their notes, and check with me for other content or quizzes.
Learning points Chapter 0
Describe the concept of the celestial sphere and the conventions of angular measurement that enable us to locate objects in the sky.
Account for the apparent motions of the Sun, Moon, and stars in terms of the actual motions of Earth and the Moon.
Show how the relative motions of Earth, the Sun, and the Moon lead to eclipses.
Explain the simple geometric reasoning that allows astronomers to measure the distances and sizes of faraway objects.

HW due Friday: SSModel: You must have chosen a solar system object before today. First SSM assignment is due, parts a-e. See your handout.
check out Death by Black Hole from the library by class on Friday.
Quiz (be able to find and zoom in on one of these bodies on Stellarium and to give distance, magnitude, and aparent diameter for any of these bodies-- our solar system planets, moon, polaris, sun, M31, M101.) you will run stellarium for the class, so practice at home. If you have any trouble doing this, see me before Thursday. Sign up for your planet or moon (etc) for Solar System Model (SSM).
October ends with an astronomy-based holiday. Halloween began as the Celtic holiday of Samhain (rhymes with HOW-when). It marked the start of the dark half of the year, which ended on May Day—or, as it is still sometimes called, Beltane. On Samhain, the evil spirits that didn't like the daylight and had been hidden for six months broke loose and made lots of trouble. So people tried to appease them with offerings of food and carved and lit gourd lanterns to ward them away. These traditions survive as trick-or-treating and jack o' lanterns.

Start SkyLog. Starting Friday night, keep a log for each night at the same time, either 9:30 or 10:00, or you can choose morning before dawn. Your assignment is to find a planet. Write this into your notebook. On Tuesday, bring your first entry. If there are clouds, keep trying.
Due Tuesday: : 2: R&D7; CST 8,10; write Astroblog on your planet; and Show SkyLog. Started Friday: keep a log for each night at the same time, or you can choose morning before dawn. Your assignment is to include the ecliptic if possible, and find a planet. Write this into your notebook.. If there are clouds, keep trying. Show me your Skylog each day we meet. Record the map for each night or early morning at the same time. Each day, look a the the same patch of sky and map 5-7 bright stars. Write this into your notebook
Due Wednesday: 2: R&D 9, 12; CST, 1,2,3,4,5, 12,13,14; skylog
Due Friday: quiz. skylog. SS Model 3-d model is due; make it 3-15" in diamter. See assignment sheet
Some of you are not treating the SS Model seriously, so I'm reminding you that it is graded as a lab, for a total of 50 points to be applied to the final exam for this term. I will apply point penalties if you are late in meeting the deadlines.
Due next Tuesday: skylog, and also find a planet in the sky; 2: P 1,3; chpt 3 R&D 1-4.
