Why Solar Eclipses Matter and Why Totality Matters More Than Anything
Friday September 8, 2023, 7:00pm – UW Space Place
There are two important solar eclipse events coming up: the October 14 2023 Annular Solar Eclipse, and the April 8 2024 Total Solar Eclipse. This talk will be a general introduction to solar eclipses with a quick look back at the August 2017 event (seen by many MAS members) but a thorough look ahead to the two upcoming events. Why should you care and how should you prepare? Everything you need to know about planning for and then observing these two events will be covered.
John Rummel is a long-time member and past president of the Madison Astronomical Society. He made his reservations for a place to stay in Texas nearly 3 years ahead of the April 2024 total eclipse!
The James Webb Space Telescope Peers Back In Time 43 Minutes
Friday August 11, 2023, 7:00pm – UW Space Place
Though we may think of the James Webb Space Telescope (JWST) as primarily intended to observe the early universe and the most distant galaxies, it also counts observing bodies in our own solar system as part of its mission. As part of JWST’s Early Release Science program, a group of astronomers and planetary scientists proposed and and was selected to observe the Jupiter system, including its atmosphere, rings, and several satellites. Many of that progam’s observations have now been completed and results are being published. This talk will discuss the capabilities of several of JWST’s instruments including the Near Infrared Camera (NIRCam), Near Infrared Spectrograph (NIRSpec) and Mid Infrared Instrument (MIRI), and what observations they conducted.

How do bacteriophages interact with their host bacteria in space?A Presentation by Vatsan Raman, UW Biochemistry
Friday February 10, 2023, 7:00pm – UW Space Place
Bacteriophages, or ‘phages’, are bacterial viruses that are the most abundant organism on Earth. While phage research has progressed considerably terrestrially, how phages and bacteria interact in microgravity is largely unknown. Microgravity presents enormous challenge for microorganisms, which are greatly affected by gravity to mediate cell-cell and cell-phage interactions. To elucidate these interactions, we explore how T7 bacteriophage interacts with E. coli BL21 in microgravity onboard the International Space Station (ISS). We incubated samples in gravity and microgravity for short- and long-term experiments, finding that lysis is delayed in microgravity conditions and suggesting this phage is inhibited in microgravity. We identified novel mutations in phage proteins that influence activity in microgravity using whole genome sequencing and examine how microgravity influences selection in phage structural proteins. Our study provides a preliminary examination of the influence of microgravity on phage-host interactions. The success of the approach used in this study provides a foundation for future research in microgravity to explore interactions between phages and bacteria that define microbial communities.

The January MAS meeting will feature a focus on astrophotography with presentations by two experienced practitioners:
Randy Trank on “Lucky Imaging and the Moon”
“Lucky Imaging” is a phrase used for certain types of astrophotography so I’ll explain that and show an example by processing a lunar photo.
Randy’s background: Randy became interested in astronomy under the dark skies of Lake Ripley when he was 12 with an Edmund Scientific scope. He loved the Apollo missions. Randy has dabbled in astrophotography for 50 years, avoiding the moon. He is now returning to his lunar roots and wishing he hadn’t avoided the moon for so long! Randy is a member of the Rockford Amateur Astronomers.
Tim Wilson on “Data collection, Organization, and Preprocessing”
Tim will cover: Light Frames: Inspection for bad images, planes, satellites, movement of mount, Dark Frames: Same temperature and Exposure Time, Flat Frames: Different methods, White Screen or T-Shirt Method, also touch on flat frames acquisition by using APT or SGP software, Bias Frames, Deep Sky Stacker: Loading files, basic settings, registration, image scores and stacking.
Tim’s background: Tim is a retired CNC and Manual Machinist; retired in 2016 from the Savannah Company in Waunakee, WI. Tim has done visual astronomy for the las 40 years, but finally tried his hand at astrophotography in 2014 and has been doing it ever since. Some of his other interests are Electronics, 3D Printing, CNC Router, CO2 laser cutting and Guitar. He has a love of science and technology and enjoys reading books on physics and astronomy. Tim is a long-time member of the MAS.
The return of the Madison Astronomical Society’s annual Holiday Party and Telescope Clinic.
Do you have a telescope that’s giving you problems? Has it been gathering dust in your closet instead of giving great views of the moon and planets? Are you stuck and can’t get to the next step? Our experts can help you diagnose the issues and get it figured out. Bring your telescope to this meeting and we’ll take a look at it with you.
Also, feel free to bring a holiday snack to share with the group. Cookies, brownies or other finger foods preferred.
There will be a short presentation by John Wunderlin, co-founder of the Iowa County Astronomers:
Title: So You Want To Buy a Telescope?
John will share his thoughts on telescope gear after almost 20 years in the hobby
John Wunderlin has been an active amateur astronomer for nearly 20 years. He co-founded the Iowa County Astronomers club in Dodgeville, Wisconsin and estimates that more than 5000 people have looked through his telescopes at outreach events over the years. He was an avid astrophotographer spending every clear night in his backyard observatory for a decade but since moving to Madison in 2014 has mostly stuck to weekend visual excursions with his 10″ Dobsonian. John founded his Spike-a.com astronomy business bringing the first commercial Bahtinov focusing masks and other astrophotography gear to the public in 2008.
