Visiting PMO in May (2018) – PMO Opens May 25-26 of Memorial Day weekend for public tours

No viewing through telescopes is planned Friday due to poor weather. We hope to see you on Saturday!

It’s that time of year – public night sky tours at PMO begin Friday and Saturday, May 25-26, of Memorial Day weekend!

Please note that there are no tours on Sunday and/or Monday, even when there is a Monday holiday.

Always check the weather forecast and the PMO weather page before visiting; you should expect and prepare for nighttime temperatures in the 40s, even if it’s nice in town. Tours begin at about 9:00 p.m. and may last until midnight, although it’s not unusual for viewing to end earlier depending on conditions, so please arrive early, and check in at the greeting center next to the parking lot.

Sunset is about 8:30 p.m. Twilight viewing beginning about 9:00 p.m. will focus on the planets Venus (in the west) and Jupiter (in the southeast), as well as the Moon, which will be bright as it approaches full phase on May 29. Saturn will not be visible during normal tour hours for about another month. If you want to experience the best dark-sky viewing of certain star clusters, nebulae and galaxies (sky conditions permitting), please wait two more weeks until the Moon is out of the way.

The PMO campground is a primitive Forest Service campground, and does not accept reservations. Although there’s plenty of space for smaller vehicles and tents, please do arrive early if you plan to camp.

We’re looking forward to another great season, and to seeing you at PMO!
