Is the aurora visible in Salzburg tonight?
Right now
Not tonight.
Kp is 0.0. Salzburg needs Kp 9+ for the oval overhead — right now it’s not reaching Salzburg.
Tonight's peak is forecast around Kp 5.3 (Minor storm). The forecast still depends on darkness, cloud and the moon at your exact spot.
Reliable about 30 minutes ahead — cloud decides the rest.
