PMO is open for the 2019 Season

Visiting PMO in June (2019)

PMO is now open for Friday and Saturday night tours, and June can be a good opportunity to visit. Keep in mind, however, that sunsets are late (8:45 p.m. or so), and you should plan on staying until at least 11:00 p.m. (weather permitting) to have a good experience including a couple of dark sky objects such as star clusters. Tours will normally not end until midnight this time of year, if the sky remains clear.

Check in at the greeting center next to the parking lot; or proceed up to the telescopes if the greeting center is closed.

Twilight viewing beginning after 9 p.m. will be limited in early June because Mars is almost gone from view, and Jupiter will not be well-placed in the southeast sky until about the end of twilight. (By late June, Jupiter will be visible in twilight.) Saturn will not be visible at a convenient hour until July. If you’re a fan of watching the International Space Station fly over, you’ll have opportunities during twilight the nights of May 31 and June 1. (We’ll announce the viewing times.)

Moon viewing information:

May 31-June 1 – new moon weekend – excellent dark sky viewing.

June 7-8 – some moonlight interference, with moon approaching first quarter and not setting until after midnight. Good for viewing the moon itself – the sun will just have risen at Tranquility Base.

June 14-15 – moon approaching full and doesn’t set until very late, so avoid this weekend for dark sky viewing.

June 21-22 – waning gibbous moon will be bright when it rises shortly after midnight; but potentially good dark sky viewing from about 11 p.m. to midnight. This is also the summer solstice weekend!

June 28-29 – waning crescent moon doesn’t rise until very late (3 a.m. or so, almost the first light of day this time of year); so potentially excellent dark sky viewing.

We’re looking forward to seeing you at PMO!

Pole Cam Update:

Pole cam clarity may be compromised due to winter conditions.
