Almost after nearly 20 years waiting time there was finally a extreme polar sighting again in southern Bavaria (Very seldom in this southern lain areas). And this was really a great fantastic event. I would even classifythis aurora as extremely bright. Abouve all the beamers in all colours were noticable very intense. The strongest phase at 20:30 - 01:30 UTC with a very high KP Index of 9o*

In the foreground the village of Rottbach near Maisach


Second Aurora beginning ca. 22.30 UTC, (00:30 CEST,11th of May),

RAGDA - spots !

But what does it means? This is a very late discovered aurora phenomenon. Red Arc with Green Diffuse  Aurora. The seldom stunnig apperance offers pulsing green clouds in accordance of red arcs. It seems that you observe a fantastic celestial disco lighting which you can OBSERVE CLEARLY WITH THE NAKED EYE ( Video 5 ).

The Claw

And one special was shown wide at the southern sky behind us (height ca. 60°). It looks like a big claw wich wanted to crab me ...

A new observation rarity ?

And the next aurora phenomen !

The SAR-Bow

And another seldom aurora phenomen appeared. A SAR (Stabile Aurora Red) bow which enveloped the whole polar light. May there ist also a second one. It was first discovered in 1954.


Third Aurora  ca. 00.10 UTC, (03:00 CEST,11th of May)

The last show

After 7 hours foto stress :-) relaxing in the twilight.

No Video ;-)


Aurora (weak visual) in the next evening ca. 20.30 UTC, ( 22:30 CEST, 11th of May )


KP index*: Roughly speaking, auroras can already be observed visually from KP 5-6 (G1/2 storm) in northern Germany. At KP 7/8 (G3/4 storm) or above in southern Germany (Alps to southern Europe). Among other things, the density and speed of the flares or CME's (earth directed solar mass ejection forms) or corona holes are relevant parameters for the strength of the solar storms and visual sightings. But the Bz value which definite the north- south  alignment of the earth magnetic field (May 24, Bz-50nT) is the most important factor. If this Bz value is to weak, the protons can't invade in the earth magnetic field. By the way, the glowing phenomenon is triggered by animated nitrogen atoms. Up to 100 km green, 100-200 km red and above purple.
