 LongmontAstronomical Society |
About the Longmont Astronomical SocietyThe 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, June 20, 7:00 PM Dr. Ricky Egeland of NCAR In 2017 I obtained my Ph.D. in physics from Montana State University with my dissertation "Long-term Variability of the Sun in the Context of Solar-Analog Stars." I am currently an NCAR Advanced Study Program Postdoctoral Fellow working at the High Altitude Observatory in Boulder, Colorado. My research is on long-term solar and stellar magnetic variability and the stellar dynamo. Solar Magnetic Variability |
 | The Sun is a giant magnet with a dynamic surface, showing varying amounts of magnetic features at any given time, most notably changing with the 11-year solar cycle. These varying magnetic features produce very small color-dependent variations in the brightness of the Sun, which allows us to use brightness changes as a proxy for the Sun's magnetism. The same principle applies to other more distant stars, allowing us to study their magnetic variability. I will discuss proxy observations of solar and stellar magnetism as well as the feasibility of observing stellar spectra on an amateur budget. Meeting location: First Evangelical Lutheran Church, 3rd & Terry, Longmont
