April 24, 2023 Severe Geomagnetic Storm
Itasca and Koochiching Counties, Minnesota
Best display I've probably ever seen. I'll update this some more as I process images.
 |
|---|
| This is the start of the big substorm that happend just after 11:00 PM. |
 |
|---|
| The auroras expanded and brightened very quickly. |
 |
|---|
| At Bigfork, looking north. |
 |
|---|
| I set up a camera with a fisheye lens looking southeast. |
 |
|---|
| The band of auroras was just barely far enough north that I could get a little bit of a corona. |
 |
|---|
| A couple cars came by on the road, so I moved the camera out of the way. |
 |
|---|
| Southern Koochiching County (north of Craigville) at 12:11 AM. Taken with my iPhone. |
 |
|---|
| I moved to a location north of Effie in southern Koochiching County. |
 |
|---|
| I continued to shoot at this location for about three hours: 11:46 to 2:38 AM. |
 |
|---|
| 24 mm shot. |
 |
|---|
| An aurora "mesocyclone". Rotation is opposite what it would be in a thunderstorm. |
 |
|---|
| Some sort of aurora beast or extraterrestrial. |
 |
|---|
| A sharp band of auroras intersecting with the horizon. |
 |
|---|
| Many interesting shapes to the northwest. |
 |
|---|
| I took an 8mm, full sky, fisheye picture before I left. |
 |
|---|
| Back at the continential divide on Highway 38. |
 |

| Pughole Lake at 4:36 AM. Contrast is becoming subdued as twilight brightens |
