[Geysers] GIANT ERUPTIONS BY MONTH

I've been told there's been some discussion on the OF webcam chat page about Giant eruptions by month.  As shown in the table below, Giant likes fall and winter best, and summer least.  June is its least favorite month, followed by May, then July and August. 
 
I excluded years prior to 1960 because winter records were incomplete for many years.  I lumped 1960-1999 together because there weren't many eruptions in the 1960's (1), 1970's (1), 1980's (8).  As a side note, 69 of the 94 eruptions in 1990's occurred between January 1997 and April 1998.  I didn't include a column for "2010 to date" because there have only been two eruptions, both of which were in January 2010.
