The Telescope was moved to a different location yesterday. It was moved about8-9 feet from it's original location. We are not sure whether this will change the rates at all so we are just testing it out now. Dr. Forest hopes to be able to use it with th edrift chamber that we recently recieved and have been working on.
Cosmic rates measured each hour when the telecope accepts cosmics which intersect the earth's surface perpendicularly (defined as zero degrees).
