Hi, Nice arc. obscured by housing from the garden. However much to my surprise the NLC cctv camera did record some of the action. On youtube at youtu.be/0veVW_i4inoNo NLC but a definite bonus! Just double checked, uploaded version shows next to nothing. The original is much better. need to work on that. |

Nice captures Tom. I think I can see a greenish tint towards the horizon on Bill's CCTV camera timelapse. Nice lenticular clouds on both the pictures and the cctv footage.

Fine that we had some luck! Here an example from Northern Germany aroung midnight / UTC. Lens 4/29mm, 800 ASA, t 20"; contrast + a bit usm enhancement for a better view here but the brighter beams have been visible with the naked eye without a problem (black + white).    IAP cam on island of Ruegen (east of me) caught a beam together with very low NLC! I had no chance here for that because of the Cumulus clouds. So have a good night. I think sleeping is a good possibility tonight. :-) Olaf |

Hi Bill, although in the the wrong place the "chimney cloud" in the middle is funny + worth to have a look at! |

Hi, Here's a crop from an all sky image. The aurora was just peeking up between the houses. It's interesting to note the purple emissions in the taller rays from extra solar UV stimulation of nitrogen since these parts are still in sunlight.  Also here's a spectrogram from the whistlers I recorded earlier in the week. What is remarkable is how many reflections the sferic makes through the magnetoshere. I get to 14 before it's lost in subsequent whistlers. I'll try and put the audio onto my uni website.  Instead I've put the graphic and audio here: youtu.be/qJAoArm1fv0 |
