A SIGMOID ERUPTION ON THE SUN

If the sky is clear on the 7th, look for auroras.– CPL

A SIGMOID ERUPTION ON THE SUN: When you see an “S” on the sun, it usually means something is about to explode. On Sept. 4th, NASA’s Solar Dynamics Observatory recorded a textbook sigmoid eruption:

Researchers have long known that sigmoid structures in the sun’s atmosphere herald strong explosions. Their magnetic field lines are twisted like a slinky. When enough tension builds up, they un-twist explosively.

This sigmoid hurled a dark plume of plasma more than 700,000 km long into space. The plume is dark because the plasma inside is relatively cool and dense–two qualities that can make potent CMEs.

The explosion hurled a CME directly toward Earth. NOAA and NASA models agree that it will reach our planet on Sept. 7th. The impact could spark a G1 to G2-class geomagnetic storm with high-latitude auroras visible during the lunar eclipse. CME impact alerts: SMS Text

NEXT CLUB MEETING COMING SOON, ON SATURDAY, SEPTEMBER 20!

MonSFFA’s next meeting is scheduled to take place on Saturday, September 20, from 1:00PM to 5:00PM!

We will gather at our downtown meeting locale, Le Nouvel Hotel, 1740 René-Lévesque Ouest (corner St-Mathieu).

Please take note: we will be gathering on this occasion, as we did last month, in the “Faubourg” meeting room, just down the hall from our usual “Maisonneuve” room.

Out-of-towners, as always, may join our ZOOM-chat and take part in the meeting from the comfort of home!

On the Agenda:

Guest Speaker on Exoplanets!

Is there another “Earth” out there ripe for exploration, and exploitation? We welcome guest speaker Riley Rosener on the topic of exoplanets. Riley, a long-time fan of science fiction, is currently researching the detection and characterization of exoplanets at Université de Montréal.

The Life, Times, and Music of Tom Lehrer!

An overview of the man who famously set the Periodic Table of Elements to music. Expect a sing-a-long!

Musician, satirist, and mathematician Tom Lehrer, who passed away this summer at age 97, was a young prodigy in the era of white bread, crewcuts, and Father Knows Best. He sang to middle-class America of STDs, World War III, and one-time SS officer Dr. Werner von Braun, among other varied subjects. Lehrer counted Princess Margaret among his fans, which boosted his profile in Britain, although most of his songs could not be played on the BBC—his records became best-sellers as a result!

Lehrer’s musical influences included Gilbert and Sullivan, and Broadway show tunes, and he, in turn, influenced Dr. Demento and Weird Al Yankovic. With no family to follow him, he released all of his works into the public domain; his songs are available, now, for everyone to enjoy!

Precognition, Prophesy, and Possibility!

We look at different ways of knowing the future, and what that does to us!

Meeting Theme: We encourage MonSFFen to have ready for our guest speaker their questions about exoplanets!

We’re looking forward to seeing as many of you as possible at our downtown meeting hall for this September 2025 meeting! Bring a friend! See you all there on Saturday, September 20, 1:00PM-5:00PM!

 

Please Note: While we strive to keep on schedule, we do, sometimes, fall behind a little, or find ourselves having to reshuffle the order of items on the agenda for one reason or another, or reschedule planned presentations/discussions. Therefore, please understand that all programming is subject to change!

 

And, we take this opportunity to remind MonSFFen, and the greater community of SF&F fans, that MonSFFA’s annual Super Sci-Fi Book Sale is scheduled for next month, on Saturday, October 25!
So mark that date in your calendars, folks, and start saving your coins and folding money for this bargain-bonanza of a chance to stock up on all your fall and winter sci-fi reading! Paperbacks, hardcovers, trades, plus many comics and magazines—we’ll have hundreds upon hundreds of titles, from Asimov to Zelazny, at the lowest prices in all of known space! Bulk Book Bargains! The more you buy, the more you save!
The Super Sci-Fi Book Sale will take place in “Salle St-Mathieu” at the downtown Nouvel Hotel, 1740 Boul. René-Lévesque O. (corner St-Mathieu)!

Science Guest Sept 20th meeting

EXOPLANETS top the Agenda, MonSFFA meeting Sept 20

Join us September 20, by Zoom or in person at the Hotel Nouvel, 1740 René-Lévesque Blvd W, Montreal, corner of St Mathieu.

Our guest speaker is Riley Rosener , a Physics Masters student at the Université de Montréal doing research on the detection and characterization of exoplanets. They recently moved to Montréal after doing a B.S. in Astrophysics (and a minor in History) at UChicago. They have been a long-time fan of science fiction, and particularly enjoy reading new SFF, exploring various TTRPG systems, and learning about unfamiliar history. They will be talking about the history and science behind the detection of the first exoplanets, modern developments in exoplanet astronomy, and their own research.

Also on the agenda:

The life, times, and music of Tom Lehrer, who famously put the Periodic Table of Elements to music! Expect a sing-a-long!
 Precognition, Prophesy, and Possibility: Different Ways of Knowing the Future, and What it Does to Us.

Guy H. Lillian III (1949-2025)

Guy H. Lillian III (1949-2025)

I was shocked today to learn of the passing of Guy Lillian, a well known and respected zine editor. Guy always had nice things to say about MonSFFA’s zine, WARP.  I had the pleasure of meeting him at World Cons, and we often corresponded. I submitted an article to an issue of Challenger, which he published to my great delight.

Guy’s Zine Challenger was nominated 12 times for the Hugo and he was twice nominated for best fan writer, but he never took home the rocket. It would be a wonderful gesture for the next world con to award a special trophy posthumously.

Meeting September 20 to feature tribute to Tom Lehrer

MonSFFA SATURDAY, SEPTEMBER 20, don’t miss Joe Aspler’s tribute to musical satirist, Tom Lehrer!

A tribute to Tom Lehrer (1928 – 2025)
By Joe Aspler

Tom Lehrer was a young prodigy, in the era of white bread, crewcuts, and Father Knows Best. He threw, or rather, sang his spanner into the works of middle class America. He sang about STDs, which left the unaware listener in a state of unawareness. He sang about Poisoning Pigeons in the Park. He provided theme songs for World War III and sang about one time SS officer Dr. Werner von Braun. He sang The Elements – all 103 of them at the time. He received a giant boost in Britain when it was found that Princess Margaret was a fan. Most of his songs could not be played on the BBC, which turned his records into best sellers.

His influences included Broadway show tunes, Gilbert and Sullivan, and society around him. In turn he influenced Dr. Demento and Weird Al. At the age of 94, with no family to follow him, he released all of his works into the public domain. They’re there for everyone now!

In this tribute, I will look at the life, times, and songs of Tom Lehrer. Concert and recording excerpts will be shown, concluding with a final singalong.

Zines to share!

We have more zines to share!

THE BACKWARD TAIL OF COMET 3I/ATLAS:

THE BACKWARD TAIL OF COMET 3I/ATLAS: Last month, when astronomers used the Hubble Space Telescope to photograph 3I/ATLAS, they had a “Eureka!” moment. The mysterious interstellar visitor had a fuzzy atmosphere and a growing tail. Clearly, it was a comet.

However, something was not quite right. Take a look, and see if you can spot the problem:

The tail of 3I/ATLAS points almost straight toward the sun. Normally, comet dust tails are pushed away from the sun by radiation pressure. 3I/ATLAS is doing the opposite—it’s backwards.

Why? Researchers led by David Jewitt of UCLA believe they have an explanation: “It is due to the preferential sublimation of ice on the hot day side of the nucleus and the near absence of sublimation on the night side,” they wrote in a paper reporting the observations.

In other words, 3I/ATLAS *is* a comet, but only the sun-heated side is producing lots of dust. The emerging dust particles are too big for radiation pressure to bend them back into an ordinary tail.

This is unusual, but not unheard of. Solar system comets have been known to produce sunward fans or jets, typically from localized “hot spots” on their rotating nuclei. What makes 3I/ATLAS different is the dominance of its sunward plume, dwarfing a barely visible anti-solar tail behind it.
