About the Longmont Astronomical Society

The Longmont Astronomical Society is a non-profit amateur astronomy club based in Longmont, Colorado. The club was founded in 1987 by people enthused about astronomy and who were looking for an avenue to share their enthusiasm with others of like interest. Since then the club's membership has grown to over 100 (both families and individuals) that embody all levels of experience and interest.  All of the photos at right were taken by members of the club.

Next LAS Meeting: Thursday, September 19, 7:00 PM

“NASA’s Juno Mission to Jupiter: Update after 22 orbits”
by Dr. Fran Bagenal, LASP

Our speaker for September is Dr. Fran Bagenal. Dr. Bagenal, a great friend of LAS, is part of the the University of Colorado.s Laboratory for Atmospheric and Space Physics [LASP]. 

Juno has been orbiting Jupiter since July 2016, passing close over the cloud tops every 53 days.

This talk will summarize the mission and discuss the science results obtained to date - including puzzling deep interior structure of the gas giant planet, dazzling auroral emissions,  as well as the amazing cloud structures revealed by JunoCam in collaboration with a vast citizen science community.


Fran Bagenal studies the magnetic fields of planets, the interactions of plasmas with atmospheres, and magnetospheric processes.

She has worked with plasma data from a variety of space missions, starting with the Voyager mission to Jupiter, Saturn, Uranus and Neptune. She was on the science teams of the Galileo mission to Jupiter and the Deep Space 1 mission to Comet Borrelly.

She edited Jupiter: Planet, Satellites and Magnetosphere (Cambridge University Press, 2004). She leads the plasma teams on the first two New Frontiers missions: New Horizons mission to Pluto (launched January 2006, flew past Pluto in July 2015) and Juno, a Jupiter polar orbiter (launched 2011, arrived at Jupiter in 2016).
