Today I answered the three questions on the post-LIGO assignment that DL sent to us. I used google maps to figure out the distance between the location of the earthquake and the LIGO station. I then used this distance to figure out the speed of the seismic waves. This assignment took me the entire period to finish.

Today in class we had a class discussion on cosmic rays. We watched a short video clip on the sun and sun spots. We are going to start working on a class project involving cosmic rays in the near future, so this was simply a brief introduction to everything. We did not have a chance to get into what exactly the project is going to entail, though.

Today in class I updated my logbook. I also went through some other people's post-LIGO assignments to see what they did and compare their results.

Today I looked up information on possible reasons for the lapse in time between the seismic y and z graphs on the post-LIGO assignment. I found that there are different sensors on the instrument that are all from different directions and are independent from each other. I think that this accounts for the differences in time. I found this information on the LIGO detector tool at their web-site.
