Comparison
Monchegorsk vs Polyarnyye Zori for the northern lights
Answer
Side by side
| Figure | Monchegorsk | Polyarnyye Zori |
|---|---|---|
| Dipole latitude | 64.0° | 63.5° |
| Kp for the oval edge overhead | Kp 2 | Kp 2 |
| Civil night, December 15 | 18.3 h | 18.1 h |
| Dark-season days | 247 | 251 |
| Nights with no civil darkness | 100 | 96 |
| Dark-month cloud, NASA POWER | 79% | 79% |
| Solar midnight, December 15 | 00:44 | 00:45 |
Monchegorsk sits at 64.0 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 2. Polyarnyye Zori sits at 63.5 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 2.
