Observations by James A. Petrait
Both of the observations in the graphs below started late on 7/18 and covered a 24 hour or more period which included all of 7/19. The one on the left (or top) was made in 2010 and the one on the right (or bottom) was made in 2011. Both used 2 geiger counters and a coincidence detector (as described elsewhere on this website) and were in the same horizontal position and location for the 2010 and 2011 readings. The 2011 reading shows a definite increase over the 2010 reading. This is consistent with other observations that are being made during the 2 year time period.
