COSine 2026 is coming up January 23-25, 2026 at the Embassy Suites by Hilton Colorado Springs.
Just wanted to send out one last reminder about COSine, which is just one week away!
The team just took up the airship to do some advanced weather checks, which is a bit odd, because I thought they just checked the weather app on their phones. This is the message they sent:
“Weather’s looking good for the con, with the happy sun symbol for Friday and Sunday, and only a bit of cloud for Saturday. Also, does anyone know how to fly an airship—the purple mountains majesty are getting awfully close…”
Online registration is now closed, but you can register at the door for the entire weekend, or for day passes.
And just a reminder of our guests—Cory Doctorow, Dr. Josiah Seaman, Michael Carroll, Connie Willis, and Courtney Willis. And more hoopy froods, writers, artists, and techies than you can shake a stick at. If you are the sort of person who likes to shake sticks at people.
And if you want even more Cory, he will be at the Tattered Cover on the Thursday before the con!
Contacting Us
Feel free to ping us if you have any questions or issues, airship driving manuals, pyranometers, working weather control devices, or really pretty seashells.
