Sidewalk astronomy, May 5

It's Jupiter opposition this week, which means Jupiter joins Saturn as part of our evening sky. At opposition, Jupiter rises at about sunset, which is about 7:30 tonight. An hour later, it should be high enough to view. Before then we'll have a nice first-quarter Moon, and Saturn as soon as it's dark enough to find it (probably about 7:50 p.m.). The only unknown right now is the weather. The forecast is for typical "May Gray" marine-layer fog. It might close in before Jupiter is available for viewing. In any case, Jane and I will be in Old Town Pasadena this evening (Friday) from about 7:30 'til 10 p.m., or until the low clouds and fog wipe out the sky. We'll be on Colorado Blvd., somewhere on the two blocks between Fair Oaks and Pasadena Avenues. Saturday evening we plan a repeat performance in Monrovia at Myrtle and Lime, from about 7:00 'til 9:30 p.m. Hope to see you!
