Re: [Phys-L] Percent of Sun Covered Duing Eclipse
We were supposedly to be in the higher 90s percent-wise but saw the
same---some darkening but nothing very spectacular. Unfortunately, I didn't
have the proper glasses and my pin-hole camera attempt didn't work too well
either.

Subject: [Phys-L] Percent of Sun Covered Duing Eclipse
Here in Baltimore one of the weather stations announced our partial eclipse
would be 88% at maximum (3:02 pm EDT). At this time, the sky did grow
darker, but not as dark as I expected given an 88% eclipse. Was the weather
report wrong, or is the amount of sunlight received by a spot on the earth
not directly proportional to the amount of the sun's disk visible at that
spot? I am ignoring secondary effects such as the sun's corona.
