Likely my last post on @bsky.app @safety.bsky.app @support.bsky.team For me, Social Media has gone off the rails. Not supplying any of the information requested below. It's been FUN.

The stealthy #solarstorm has arrived and it is beginning to really look good for #aurora shows, despite being pretty slow. Aurora chasers in the Western and those down under should get some decent periodic brightenings through morning as substorms ramp up!

Compromised Antenna? Not Today! AX1 Activation at Fort Dobbs State Historic Site
On Tuesday, September 9, 2025, my wife, Hazel, and I were heading back from Greensboro, NC along Interstate 40 when I thought it fitting to make a short detour to Fort Dobbs State Historic Site for a quick POTA activation. Fortunately, both my wife and Hazel agreed. We all wanted to stretch our legs, and Fort Dobbs is a wonderful park to do just that.

KV4AN: A Pair of Quick Drive-Up SOTA Activations in Northern Alabama
By Steve (KV4AN) My XYL and her sister like to go yard sale-ing on Saturday morning (this is the practice of buying other people’s junk so you can throw it away for them), so I’ve had two beautiful Saturday mornings to do a pair of quick drive-up SOTA activations here in Northern Alabama.  The first Saturday, I went to Gunters Mountain, which is around an hour away near Swearengin, Alabama.

Hurricane Helene: One Year Later
One year ago today—September 27, 2024—Hurricane Helene moved up from the Gulf of Mexico, swept across the Southeast, and struck Western North Carolina. Its impact was massive—its destruction, unprecedented. by Thomas (K4SWL) The Storm Arrives We’d been following weather reports in advance, expecting heavy rain, localized flooding, and some winds. That’s not unusual here—we often see the remnants of hurricanes and tropical storms.

Sometimes the best therapy Is building a kit. One of the great things about going to Four Days in May during Hamvention week is attending vendor and club nights at the Holiday Inn Fairborn. It’s incredibly rare that I go to this event and don’t walk away with one, two, or three kits. I’d say the same goes for most other attendees.

by Mark (KB2PIZ) Last weekend, I had a business meeting in Seattle and decided to take a scenic drive afterward. I planned to travel up Route 20 from Seattle, pass through Whidbey Island, stop at Deception Pass, and then continue north to Canada on Route 99, with an overnight stay in Whistler. Well, Deception Pass was more beautiful than my wife imagined, and she wanted to spend some extra time walking on the beach and enjoying the view.

One of the joys of writing up field reports is reliving POTA and SOTA activations. Since our travels in Canada this summer, our family has had a lot of irons in the fire. My available time has been almost non-existent, so I’ve only managed a handful of POTA activations. What I didn’t get in quantity, though, I certainly made up for in quality.

One of My Favorite Places on Earth: An ATNO POTA Activation in Tadoussac, Québec
There are few places on this earth that I love more than the region of Québec around the town of Tadoussac. Tadoussac sits where the Saguenay River—really, a dramatic fjord—meets the mighty St. Lawrence Estuary. Long before Europeans arrived, the Innu people had used this place—known to them as Totouskak—for thousands of years as a seasonal base for seal hunting and trade.
