Aurorae
I saw my first aurora on the night from april 5 to 6, 2000. I was alerted by an e-mail that an aurora could currently be watched. I just watched it and did not take any photographs. I should have stayed until after midnight because the most spectacular displays could be seen after midnight. But I had to work the other day and to get some sleep before.
On the night from july 15 to 16, 2000 things were different. Two days in advance aurora-alerts came in by e-mail. I watched the cloudy sky the whole evening. As the hours went by the clouds disappeared. This time I had my camera ready. At midnight the sky was cloudless to the east, to the north, to the west an in the zenith.
Exactly at midnight the spectaculum started with a corona. Bright streamers went up from the horizon and met in the zenith. To the north I could see from time to time a greenish bar. After that the western and northwestern sky glowed red and purple. The Big Dipper was in the northwest. Again and again I could see streamers crossing that asterism but never forming a corona again. The show stopped at 00.40h, and I went to bed happily. This time I was able to take some nice pictures in front of my house.
Date: 16.07.00, 00.00h-00.30h CEST Lens: 28 mm, f/2,8 Guiding: none Exposure time: 30 seconds Film: Kodak Royal Gold 100 Unfortunately I forgot to focus the lens properly. The stars became fat blobs. But the streamers that met in the zenith near Vega forming a corona can clearly be seen. |

The stars of the asterism called Big Dipper shine through the aurora. Meanwhile I corrected the focus. |
