Excellent sky conditions expected this weekend (June 23-24)
After poor sky and weather conditions earlier this month, things have improved greatly, and we’re expecting an excellent weekend of viewing on Friday, June 23 and Saturday, June 24. The sky should be dark (no moonlight) and transparent, and nighttime temperatures at PMO should only dip into the low 50s. (However, there will be a light wind, so be prepared!) Since large crowds can be expected, please arrive by about 9 p.m., and check in at the welcome center next to the parking lot. Visitors who can stay until midnight may have the opportunity to observe some galaxies in the Hercules Cluster of Galaxies, located about 500 million light years away!
