September 30 Auroras
Pughole Lake
I drove up to Pughole Lake to watch auroras.
| Steady auroral arc. This means a substorm is probably coming soon. |
| The substorm starts. |
| I dropped the exposure a bit on the camera as the auroras intensified. |
| Auroras expand to cover most of the northern sky. |
| Late phase of the substorm: patchy auroras fill more of the sky. |
