By tomorrow it may be far enough from the limb for me to pick it up with the big binocular. It looks like a big primary spot.   Groups Spots R North 0 0 0 South 0 0 0 Total 0 0 0 R = (Groups * 10) + Spots)

Observing Location	MetOval
Observational Period	2145-2215 EDT
Atmospheric Conditions	Cloud Cover Hazy Temperature 82°F Wind Light Breeze Humidity Moderate Feels Like Very warm and moist This afternoon I got an email from Peter inviting me to join him observing at TotL then got a follow-up message saying that it is very hazy out. I told him I might sneak out close to the house if there wasn't too much haze around the Moon and he said he was thinking the same thing. From where I am sitting I can’t see any clouds but can only see one star, Arcturus. The binocular required constant focusing. Transparency Poor Seeing III
