  • SMAS meeting – NEW LOCATION

    We are going to be meeting at the Bridger Charter Academy library, located in the Bozeman High School for our October 28th, December 1st and our January 26th meetings.  We’ll re-evaluate and possibly reserve more dates.  We’ve had meetings at the public library, but some people have been locked out.  Some meetings at the firehouse, but can’t always get the dates we want, and some at the Sore Elbow Forge -thanks to owner and SMAS VP Tom Holcombe.  It was costly to meet at the Commons for the Winter Lecture Series, then we found out about the 501c3 pricing through the district.  Click on the picture below for a better view!

    Optics in the Air16806950_1248884115205139_3774019949648302751_n

    The world around us is full of beautiful and interesting displays of light and color, ranging from the colors of the sky and rainbows to the swirling Aurora Borealis. Many of these optical phenomena can be seen from an airplane, and some are best viewed while airborne. This talk is an introduction to optical phenomena in the natural world, primarily in the atmosphere and seen from an airplane (“in the air”). We will follow a simple approach that can be understood and enjoyed by all levels of scientific training.
