Back to Project Page Back to Logbooks

Today I worked on making logbook enteries. I haven't been caught up on logbooks for awhile when I was working on error bars. I managed to get caught up with everything today so I can focus on the rest of the work for the project. I don't think CM and I are going to go to the science fair because we aren't ready for the fair.

Today Dr. L talked to us about where our project was heading and we are stuck. He said that our project doesn't really have much that we can do, so we will probably work with other projects. CM and I will probably work more with the class project when that becomes apparent. We are uncertain what to do for now, but we will think of something.

Tonight is the night of a total lunar eclipse. It should start around 8:30 tonight. Hopefully the weather will cooperate and I will be able to set up my telescope. It is a decent one that I can use. I dont have a camera attachment though so I probably won't be taking any pictures.

Today I looked up information about lunar eclipses since last night was a total lunar eclipse. The next lunar eclipse won't occur till 2010, but one of my classmates told me something interesting. He had heard that, because of the moon's angle, there is usually a solar eclipse either 2 weeks before or after a lunar eclipse. This is interesting to me. It makes sense and I want to look up to see if its true. The questions I have about it: 1. Is it true that a solar eclipse occurs around the time of a lunar eclipse? 2. Does a solar eclipse have to have a lunar eclipse or vise-versa? I'll go to NASA's website and start recording data about past and future tables of lunar and solar eclipses and see if its true

Today I started making an excel sheet to see and compare a lunar eclipse time with a solar eclipse. So far its true, there is no data point that doesn't have a pair of the other eclipse. There is one instance were one lunar eclipse had a solar eclipse before and after it. There is also another instance where there was a lunar eclipse before and after a solar eclipse. However there is no instance where it is solar solar lunar, lunar lunar solar, etc. A solar or lunar eclipse appears to have to have an accompanying eclipse within 2 weeks.
