After the morning meeting I stayed in the reading
room to work on calculating the speeds of coronal mass ejections (CME). Yesterday I unfortunately was researching a
CME that had insufficient data and so today I had to pick a new CME to begin
measuring. I am really enjoying my work
because all the pictures of the sun are amazing and the movies of the CMEs
being ejected are really interesting. Part of my job is to find a CME that is headed
towards Earth on one instrument, and then to find the same CME, in picture form,
taken from another instrument. The three
instruments that I am using are called SOHO (Solar and Helioshperic
Observatory) and STEREO- A and STEREO- B. A and B stand for Ahead and Behind the Earth's
orbit. I was able to get a speed of the
CME but I only found it in pixels per second and I need to convert it to
kilometers per second. The way I am
going to do that is by comparing how many pixels equals the diameter of the
sun, which I can find online in kilometers. I went up to the Multi-Camera Array lab, where
Elizabeth, Killian, and Nate work, because the reading room was a little noisy
and I just wanted a quieter place to work with people around to help me if
needed. An undergraduate student helped
me download software that counts pixels in an image so that I wouldn't have to
count them myself. It was also
movie-Wednesday and all the interns went down to the movie room in the CIS
building to watch some TED talks. They
were really interesting and we also got free pizza, popcorn, and drinks! Overall
it was a really great day!
