Analemma Society Programs

  • Looking into the Sky

    Analemma Society in cooperation with Fairfax County Park Authority is in the process of upgrading the Remote Accessed Telescope Observatory (RATO) for astronomical imaging.

  • Roll-Top Observatory

    The Roll-Top observatory holds free public observing every Friday night, weather permitting. 

  • RATO

    Analemma Society uses the RATO observatory.  The Roll-Top Observatory complements this for public observing made available through Fairfax County Park Authority for astronomical observing events and educational classes.

  • Public Observing

    The Analemma Society hosts free public observing of the heavens each Friday night, weather permitting

  • M13 Globular Cluster

    Analemma Society has educational programs throughout the year to dexplain astronomical objects and their relevance to our lives.

  • Roll-Top Observatory

    Fairfax County Park Authority opened the new Roll-Top observatory and classrooms in September 2011.  The facility is now used extensively for Fairfax County Park Programs and Analemma Society Friday night observing and educational programs.

  • Veil Nebula

    The Analemma Society was founded in 1998 to foster science through astronomy.  Star-Gazing at the moon, stars, and deep sky objects is a regular public event.

Bill Burton took the photo below from Shafer Canyon Overlook, Canyon lands National Park on the morning of Sep. 28th, one day after the comet reached perhelion, its closest approach to the sun.  On Oct. 1st the comet will be just barely visible in the morning sky just before dawn.  You may be able to view the comet for a few minutes before dawn breaks and the sky becomes too bright.

The comet will pass around the sun and appear in the eveing sky just at dusk starting around Oct. 9th. Its journey comes once every 80,000 years and this time we're set for a good view. The comet brightness versus twilight will peak between Oct. 11th and 13th.  On the 12th it will pass closest to earth when the comet will be a bit higher in the western sky, but visible low on the horizon as late as 7pm.  If predictions are correct, the comet will be brighter than the planet Venus. Dr. Massey of the Royal Astronomical Society  suggests, "I think my general advice for hunting something like a comet is use your eyes, but also ause a pair of binoculars, sweep around - if it's as bright as expected hopefully it will be fairly obvious to pick up."

A live stream of the comet is set to be broadcast by the Virtual Telescope Project, courtesy of Dr. Gianluca Masi on 9 October, which will aim to capture the event from its observatory in Manciano in Italy. Visit https://www.virtualtelescope.eu/
