Epic Northern Lights in Pennsylvania

I had a distraction this week. The space weather forecast was redlined. It couldn't get much better. A long period of Kp 8 was predicted from sunset into the next day (as I shared with you in a news post).

A Kp 8 could be visible from my yard in central Pennsylvania. But then, I remembered Bryan's Law of Astronomical Events: If there is an astronomical event happening, all locations within a reasonable drive will be totally cloud-covered.

So, shocking was the National Weather Service forecast for 0% cloud cover and 0% wind speed, an unbelievable combination for an unusual night sky event I'm chasing, and that forecast was for the duration of the Kp 8 prediction. Game on. An adventure began.

Reasonable Northern Lights displays are rare in central PA, and I didn't have a go-to location list prepared for this opportunity. I needed good visibility of the sky and wanted dark skies, especially to the north, with a foreground subject being a bonus.

Shooting from home was an option. A nearby field provided the desired visibility, and our sky is moderately dark, especially when the air clarity is high. I could drive a short distance from the house and be shooting in minutes.

Still, the forecast was outstanding enough to make researching an even better location worthwhile. That my wife hadn't seen the Northern Lights in about two decades and had recently asked to see them again raised the bar on location selection.

Scouting the Pennsylvania state forest maps for vistas looking north and online scouting via images captured from those locations provided a few good options within a couple-of-hour drive. However, a high elevation (for PA) lake I scouted for Milky Way photography earlier in the summer was in a dark sky location with no close towns to the north. Most subjects are even better when their reflection is included, and the rare 0 mph wind forecast made the lake option seem especially great. A bonus was that the lake was a 1.5-hour drive north, deeper into the Northern Lights visibility range.

The lake was a perfect location. It was calm, and we (and a pack of loud coyotes) had it to ourselves for the entire night.

Reaching Kp 8.5+, the 10/10/2024 Northern Lights show was a 10. I've had the privilege of viewing and photographing the Northern Lights numerous times, but this show was different from what I normally see. The lights did not have a strong structure and they were not hte brightest I've seen, but the color was wild, with the reds and even some blues being especially amazing.

Consider the Northern Lights a fast-moving subject, as they are often pulsing and dancing. A wide aperture lens is needed to avoid strong motion blur, the smearing of the aurora details.

My favorite two aurora lenses, the Sony FE 14mm F1.8 GM and FE 24mm F1.4 GM Lens, each mounted to an Alpha 1 body for fast switching, were in the MindShift Gear BackLight 26L. Both lenses performed superbly as always.
