3 p.m.-4 p.m. I got to work on my computer model of energy and mass flows in the solar corona. If you look at some of the pictures of the Sun-like the FeXII images from EIT on SOHO-you can see that there are bright loops on the Sun. These loops are material and energy flowing through the Sun's atmosphere. I have developed a computer model to try to understand why the loops look like they do. I modify the model program to see how changes in energy and mass would change the way the loops look. I then compare the model results with observations. This is one of the tools we use to better understand how the Sun works. I'd really rather spend more time working on the model-this is real science, discovery. I seem to get the least time to spend on the best part.

4 p.m. to 6:30 p.m. I worked on my e-mail from the weekend and this morning. Some of it had to do with helping prepare the LIVE FROM THE SUN program (reviewing scripts for scientific accuracy.) I also took a short trip over to the SOHO operations center (another building here at GSFC, about 1/4 mile from my office). I saw some of the data that came in yesterday and discussed it with some other scientists. We looked at some brightness images and velocity images that had just been taken of the Sun.
