Edmonton vs Lloydminster for the northern lights
Answer
Side by side
| Figure | Edmonton | Lloydminster |
|---|---|---|
| Dipole latitude | 60.0° | 60.2° |
| Kp for the oval edge overhead | Kp 3 | Kp 3 |
| Civil night, December 15 | 15.0 h | 14.9 h |
| Dark-season days | 365 | 365 |
| Nights with no civil darkness | 0 | 0 |
| Dark-month cloud, NASA POWER | 67% | 65% |
| Solar midnight, December 15 | 01:29 | 01:15 |
Edmonton sits at 60.0 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 3. Lloydminster sits at 60.2 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 3.
