Interplanetary Magnetic Fields
Watch whether Bz turns southward and whether total field strength remains supportive of stronger aurora.
Interplanetary Magnetic Field (Bt): -- nT
Real-time total IMF strength from the last 2 hours. Stronger Bt often supports better aurora potential.
Interplanetary Magnetic Field (Bz): -- nT
Real-time Bz direction from the last 2 hours. A sustained southward Bz is especially important for stronger aurora.
IMF Bx Component: -- nT
The X component of the IMF in GSM coordinates, pointing roughly toward the Sun.
IMF By Component: -- nT
The Y component of the IMF in GSM coordinates, lying in the ecliptic plane perpendicular to the Sun-Earth line.
IMF Longitude (GSM): -- °
Longitude of the IMF vector in GSM coordinates.
IMF Latitude (GSM): -- °
Latitude of the IMF vector in GSM coordinates.
