Tom, Maybe because Vekol is much closer to the Phoenix Heat Island. The Clear Sky Clock indicated this also, although only about one level of difference in humidity. By the way a great addition to the Clock! Rick R. SAC PS: Thanks Mr. Coe for the magnificent view of Saturn from Sentinel in the Nexstar 11. PSS: I also viewed three comets: 78P/Gehrels, Tucker & Machholz. And, enjoyed the meteor showers. The Schwaar 10" f5.8 took a nice bath overnight. ;-) PSSS: Thanks to Jack Jones for getting the Porta-John. PSSSS: The obligatory, "A great time was had by all!" -----Original Message----- On Friday night, only 60 miles to the east of Sentinel, we experienced humid conditions at Vekol, but no dew when I packed at midnight. I expected much worse. It sounds like Vekol was dry on Saturday night as well. I wonder what is different about the sites that kept Vekol dry last weekend.
