Hej Helga ! Thanks for the answer, I had a feeling it might be something like that; it is nice to hear we can expect something to-night. Limiting magnitude is only +1 now but it might clear later, that has happened often this week. I guess there is no sleep for me till six in the morning ... greetin...

Hi all ! Ehm, according to the simulation of the solar wind sectors, a sector boundary crossing (I hope I have the term correct) will happen to-night. The simulation can be seen at: http://gse2.gi.alaska.edu/recent/javascript_movie.html I have a few questions, perhaps someone knows the answers ? - W...

Well, after a long night of auroral time-lapse photography, it is always nice to go out and shoot a "free" pic. The little house is next to the lake and people cook the fish they catch here in summer. Since we had a heatwave today (temp +4 degrees C and 6 Bft wind) I literally had to "...

Hi Lutz and others ! Yes, I think it could have been the C2, in combination with the trailing edge of the coronal hole stream. Some sort of ('canibalistic') wave forming effect that at first slowed the C2 CME down. Yann looked up the proton densities of the last few days and saw a gradual rising in ...

Hi there ! Under a thick Lapland cloudcover I've been watching Bz for the last 8 hours and it has been steady south now already for about 4 hours. Scandinavian magnetometers have recorded fairly large disturbances and the Norwegian line has also recorded disturbances over Denmark. With Kp prediction...

Hi All ! We're in Lapland now (Porjus, Sweden; me, Yann and his girlfriend Cindy) and we're wondering if the C2 at around 23 UT on 23 January might have any effect here; we couldn't detect a CME but it might have been too faint for the Soho cam to record. It is snowing here now all day but both nigh...

Thanks Lutz ! Yes, without text and clock it would be better but it is the only way to be sure it doesn't appear or on other sites or on TV without my permission. Some cinematographers put the copyrightsign in the middle of the clip, that would go too far for me. I used Adobe After Effects 6.5 for e...

Hi All ! I've added some aurora footage that I shot in Lapland last February to my site. Also a clip of pulsating drifting aurora. The two clips are part of the aurora movie that I showed at the Treffen. I've changed most clips on my site to better resolution quicktime movies, but mpeg1 is usually a...

Thanks Helga, I'll be there !

Nice, I'll be there and take my film also. I would need a beamer with real 1024x768 resolution plus a "soundsystem"; an amplifier plus soundboxes, that can be fed from a minijack coming from my PC. A quitar amplifier (mono) would do also. Instead of a single viewing, the film can be looped...

Hi all ! There was a discussion about a 2005 AKM PolarlichtBeobachterTreffen in autumn/winter 2005, but I cannot find the thread anymore. Will there be a treffen ? December would be difficult for me (1st week O.K.). I've recently finished a 17 minutes aurora film with Terschelling and Lapland aurora...

Hi !
This summer an international group of young meteorologists is doing sprite research on the Pic du Midi observatory in the Pyrennees in France.
They've already caught a few nice pics that can be seen at

Hi Torsten !

Absolutely phantastic images !!! I haven't found a pc yet with DivX installed, but I'n very anxious to see the animations !

sorry, I meant PMC's (Polar Mesosphere Clouds), not PSC"s (Polar Stratosphere Clouds = Mother of Pearl clouds)

Hi, this article suggests a link between NLC's (or PSC's) and the launch of the Columbia:

Hi Daniel The thing that in my view looks like a broad tornado is quite in the beginning of the clip, in the background behind the archcloud. I also detect a counterclockwise turning of that dark near-ground cloud. I spoke to observers in the path and they reported cicular movement of wind and debri...

Hi there On 4 July 2005 we had a major storm over the island and I managed to time-lapse film an arch cloud (rolwolk, Cumulonimbus arcus) with a small tornado (windhoos) connected to it. you can find it at http://www.timelapse.nl/s1page.php?p=pag&pg_id=39 or through http://www.timelapse.nl Thusf...

Hi ! I've posted the footage that I shot of NLC's in the night of 01/02 July 2005 on my site at http://www.timelapse.nl/s1page.php?p=pag&pg_id=38 or just go to http://www.timelapse.nl It is a mpeg1 4,4 MB clip that should be visible on all systems (some of the newer Apple browsers seem not to be...

Hi Christian ! Ehm, yes, from what I've figured out Werner observed from the middle of Germany and I from the north of the Netherlands (53.3N, 5.3E). I'd say I was 200 - 300 kilometers westward of Werner, that is aproximately 2 - 3 degrees west, the sun goes 15 degrees per hour, so I was 10 to 15 mi...

Hi Werner ! I also observed the NLC's last night. I observed from dusk to dawn and around 01:30 MEZT the first NLC's became visible. In the time-lapse sequence they became visible about 20 minutes or so earlier. I observed the same bright and long single cloud that you photographed, at an azimut of ...
