Astronomical Observing at Fishcreek - Friday 6/22/2007

As promised, our observing events in Stow have returned and we have an extra-special night on Friday!  The newspaper is sending Michele Kisthardt, reporter, and Michael Dakota, photographer from Record Publishing.  They're doing a story on the astronomy events we have at Fishcreek School.  The Parks Department is very interested in us coming out in force to show how popular this program actually is.  The weather forecast is calling for 'partly cloudy', but that implies 'partly clear' so let's get out there and observe!  Saturn is putting on quite a show, as is Venus, and now Jupiter.  Mercury has become lost in the glare of the Sun.  The Moon will be a few hours past first quarter so there will be lots of detail visible on the terminator - the line between the lit and shadowed sides.

We hope to see you here for a night under the stars - our twelfth year.
