The viewing conditions for a summer sky event, the Perseid Meteor Shower, should be great on Saturday-Monday when the peak meteor count is expected.
The much-needed break from the heat is being supplied this weekend by a center of high pressure coming in from the north. Most highs do a great job of supplying not only cloud-free conditions but also bringing in a transfusion of cleaner, less humid air leading to great sky-watching! Also, a crescent Moon means very little meteor-masking light.
The Perseids are the premier meteor shower of summer occurring in August. They are caused by earth’s orbit traveling through the debris path of comet Swift-Tuttle.
According to this NASA write-up, the early morning of the 13th should provide the best show with a waning Moon and two planets coming close to each other!
