At 4:32am this morning my cell phone woke me up with a text alert from my northern lights application Aurora Pro. It indicated that the current KP index over the Ludington area was a level 7. I then looked at the weather application on my phone and it said the skies over Ludington were currently clear. I shot out of bed and rushed to the Ludington State Park. From the top of the second tall dune north of the Beach House, I made this 40-minute exposure of northern lights over the dunes and Lake Michigan. Big Sable Point Lighthouse was also shining bright in the distance. I knew from experience, with a long enough exposure, the stars would appear to move in a circle around the North Star. It was a magical morning all alone on that dune today! Nikon D850. F4 at 2427 seconds, ISO 100. 14-24mm lens at 24mm. On a tripod without a flash. March 20, 2021, at 5:33am.
