Nothing scientific but I've noted in recent years that the number of cloudy nights has seemed to increase, even in the summer. However 3 or 4 years is not a trend, it's a variation, an anomaly. Let's keep our fingers crossed for 2011. However I think (educated guess) 2011 will continue the variation or trend. I hope I'm wrong. Let's see what your logs say after this coming year.

Monday night wasn't too bad. It has not been a good couple of months especially with missing the lunar eclipse. I hope with you that 2011 is an improvement . . . but I know the next several days aren't going to help 2010. On Wed, Dec 29, 2010 at 12:19 AM, Patrick Wiggins <paw@wirelessbeehive.com>wrote:
With the year drawing to a close I pulled out my observing log and calculated how many nights were good enough weather-wise for me to take data this year. Worked out to 138.
Just for the heck of it I then compared that to the number of nights I was able to take data in the past few years.
2007: 157 2008: 187 2009: 169 2010: 138
No doubt climatologists will say 3 years do not make a tend but I be lying if I said the downward trend the past three years didn't concern me.
Here's hoping 2011 will be better.
