Hi All,
Here is where I discovered that I really needed to extend my data collection by at least 2 weeks. 8 weeks prior to the summer solstice is the beginning of the Es season. It really doesn't end until 10 weeks after it. Usually I did see the first inactive day around August 15. I do take care of the 2 additional weeks in the probability numbers to be shown later on.
In the first years activity was high early in the season. The final 3 years saw more of the opposite, activity high in the latter half. I was very surprised that the weekly figures were less smooth. There was no doubt that there was an outside influence.
Again, more to come.
