Antares winked at me through conifer tops from across Secret Lake in northern Minnesota. The bright crimson star in the constellation Scorpius was setting southwest an hour after the sun.
In my 15x70 binoculars Antares was a coruscating pinwheel of light — red yes, but also flaunting glints of blue and white. Given the shallow arc of its descent the star eased behind two Norway pine crowns before sinking — from my viewpoint — into the forest. I used that as a cue to launch the hunt.
It was relatively mild for the second week in October, but I’d bundled up enough to be comfortable on the bench in my “blind.” Though there’d been a dozen ring-necked ducks on the lake that morning, I wasn’t hunting waterfowl but a comet.
This wasn’t fated to be a spectacular, hysteria-inducing event. Comet 2025 R2 Swan was estimated to be at 5.7 magnitude brightness — that is, just at the threshold of naked-eye visibility in a backwoods sky with clear, steady air. I had that, and rated the observing conditions as “very good,” but didn’t expect to see the comet without optical aid. It was predicted to be only 5 degrees above the horizon at dark, so there’d likely be at least a smear of haze, plus the natural thickening of the atmosphere at that low angle.
Starting along the horizon from Scorpius, I panned with the binoculars to the constellation Libra and just beyond. At the end of the slow sweep past dim stars I raised the lenses a couple of degrees and tracked back east, repeating the process up to 10 degrees above the tree line. Nothing.
I took a break, focusing on M13, a globular star cluster in Hercules, then did another sweep. No comet. Fifteen minutes later, on my third scan of the low southwest, I whispered “yes!” As often happens with dim targets, the comet abruptly popped into view.
