TITLE: Aurora – One of Nature’s Amazing Light Shows
Last year, California was treated to four — rare for California — auroral displays. Some of them were strong enough to be seen in the greater Bay Area. What causes them? How did they get this far south? Can you see the aurora with the naked eye? Where do the colors come from?
Marsha Kirschbaum, an avid astro-landscape and deep-scape photographer, will talk about some of the science of auroras and her experiences photographing the Aurora in Alaska and California. She will talk about the equipment she used; camera settings, and how to prepare for and protect your camera and body in the cold should one head north for an Aurora experience.
About the Speaker
Marsha Kirschbaum grew up in Anchorage, Alaska. As a child, she sat outdoors and drew pictures of the stars and night skies. Later, during a photography workshop, she discovered that she could photograph the night sky and has continued to aim her camera skyward after the sun has set whenever she has the opportunity. While Marsha has had no formal photography training, she has benefited from the mentorships and teachings of friends and workshops. Her husband, Howard Brainen, a skilled photographer in his own right, has guided Marsha along in her photographic journey.
Her image of Comet Panstaars was shortlisted in the 2013 Royal Observatory Greenwich Astronomy Photographer of the Year competition. Her night sky photography has been published in Bay Nature Magazine, Marin Magazine and most recently San Diego Magazine. She is currently a member of the Berkeley Camera Club.
This talk will be available live and publicly at:
Telescope Makers’ Workshop
The Telescope Maker’s Workshop is one of few regularly scheduled such workshops in the world! Every Friday from 7 to 10 PM, amateur telescope makers from the bay area meet at the Chabot Space & Science Center and learn how to grind, shape, polish, and figure mirrors for reflecting telescopes, under the guidance of EAS volunteers. The workshop is free; participants pay only for the mirror blanks and grinding tools, which generally cost between $100-$300, depending on the size of the mirror. All the instruction, grinding grit, testing equipment, and camaraderie is free of charge! For more information, email Richard Ozer at [email protected], or come by the workshop any Friday to see what it’s all about.
Outreach
EAS sends volunteers to schools, libraries, and anywhere curious aspiring astronomers gather. EAS volunteers bring their own equipment or borrow telescopes. Students, parents, and teachers are always thrilled to look through the telescopes and ask questions. You’ll meet all sorts of interesting people and provide a unique and inspiring experience to kids and parents who may have never looked through a telescope before.
Inquire about and request visits by e-mailing EAS Outreach Coordinator Raymond Howard at [email protected]. Visit our outreach page to find out about upcoming events.
Members Only Viewing Nights (MOVN)
Once a quarter, we schedule a Members Only Viewing Night at the Chabot Telescope Deck for both EAS and Chabot members. This is our opportunity to look through Chabot’s historic instruments and research telescope, as well as bring our own equipment to share in a more quiet venue. The schedule for MOVN will appear in the event calendar below.
Barcroft High Altitude Star Party
Reservations for the Eastbay Astronomical Society’s Barcroft High-Altitude Star Party are now open to members of the EAS, the Tri-Valley Stargazer’s, and the Mount Diablo Astronomical Society clubs. This year’s event will be held the nights of Wednesday August 20th through Monday August 25th. That’s six nights, leaving the site by noon on Tuesday the 26th. Registration is required and now open.
Please read and follow these instructions carefully.
Before sending payments for reservations ($90 per night*, per person), even if you’ve been there before, please contact Don Saito FIRST ([email protected]) to ensure the dates you wish to attend are available. You will also be asked to read the current Barcroft Writeup (ver 1.7), as it provides the information you’ll need to have a safe, comfortable stay, and what is expected of guests to this University of California research facility.
So, three steps to apply:
1. Attest in writing/email that you read the current Barcroft Writeup and sign the Waiver.
2. Email Don Saito at the above address to check reservation availability and make reservation.
3. Pay the number of days reserved via PayPal or check/snail-mail.
Barcroft is one the premier amateur astronomy view sites in the world, and it’s slightly less than a day’s drive from the Bay Area to its location in the White Mountains.
Space at Barcroft is limited to a maximum of 25 people per day, so to ensure you get the days you want, make your reservations early. When entering the range of dates you plan to attend, please indicate the starting night (the day you arrive) and the ending night (the date of the evening before you actually leave.)
* This rate is expected to increase in the not too distant future.
Calstar
Spring Calstar 2025 is scheduled for April 23 – April 27 at Lake San Antonio. Fall Calstar will be held on September 17 – September 21. For more information visit https://calstar.observers.org/
