Visiting PMO in June (2016)
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 (also known as deep sky objects) such as star clusters. Tours will normally not end until midnight this time of year, if the sky remains clear. Do arrive early (by about sunset), and check in at the greeting center next to the parking lot.
Twilight viewing beginning about 9:00 p.m. will focus on the planet Jupiter, well-placed in the SW about halfway up in the sky. Mars and Saturn will be high enough to see a little later, but before skies are completely dark. They will be low in the SE sky, near the zodiac constellation of Scorpius.
Moon viewing information: June 3-4 – new moon (not visible); June 10-11 – moon nearing first quarter, good opportunity to see during tours; June 17-18 – moon almost full (and bright); June 24-25 – moon approaching last quarter, doesn’t rise during tours.
We’re looking forward to seeing you at PMO!
