Blue Jet captured in Western Australia

Here in Europe this fact may go unnoticed, but today 26 January 2014 is Australia Day! A fitting moment to share an outstanding piece of Australian natural beauty captured by Jason Harris in Broome, Western Australia on January 3rd this year.
Jason: "As it turns out I actually have more than one from the same event. The particular storm was probably around about 60km from my location in Broome from what I can make out from radar images at the time. The particular storm fired off the first jet during a period of rapid fresh updrafts. Obviously I wasn’t at all prepared for it but I immediately adjusted some camera settings on the off chance it might fire again and after a period of pretty intense CG discharges it quietened off for say 30 seconds before firing 4 more jets within a period of about 30 seconds, all of which I managed to capture. I have been told one of the shots is perhaps a “starter” but it may also just be a case of not picking up the full channel. I will say this, no photograph can EVER do justice to what I saw with my own eyes. Truly spectacular event that I won’t forget in a hurry."
Asked about the storm's flash rates and development, Jason added:
"I first set up the camera around 10pm framing up a couple of other discreet cells further to the south of the particular storm that fired off the jets. The original storms were probably over 150km away as I was shooting at 200mm. The storm in the photo went up on the outflow boundary of the earlier storms around 11.30pm and continued for perhaps 2 hours while tracking from the east to west towards Broome. The jets were fired off in the formative stages of the thunderstorm between about 11.35 and midnight. After that the storm went through several stages of redevelopment but became somewhat cluttered with strata rubbish as it moved closer. GPATS data from the night suggests around 3000 CG strikes emanating from this storm during it’s lifetime so not overly active by Kimberley storm standards but certainly not a “quiet” one neither."
Additional images and information was shared on a weather forum:
Lee Crees, a friend of Jason, captured his first sprite:

CETLE - Facebook group for Central European TLE observations

A new user group has been created on Facebook in order to collect posts related to TLE observations specifically in Central Europe.

Messages and reports about TLE observations keep appearing on Facebook timeline from more individuals. Now there is an option for anyone to share his/her observation plans and experiences with others who are interested.

The group is also supposed to serve as a forum for anyone to ask questions about TLE observations or about the TLEs themselves.

News from Italy

For the moment we can forget about thunderstorms and TLEs in central Europe but it doesn't mean there is no action somewhere else!

December has been good so far for Italian observers in Medicina and elswhere as the CIPH-SOSO News blog reports.

CIPH-SOSO is part of the Italian Meteor and TLE Network, IMTN.

Thanks to Renzo C. for sharing the news.

An odd TLE detection from Central Europe

A huge thunderstorm swept through the common borders of Germany, Poland, and the Czech Republic in Central Europe on the night of 2 July, 2012. The storm was producing TLEs all night. Martin Popek from the Czech Republic has set his camera in Nydek to watch the firework of sprites. The TLE camera in Sopron was monitoring the same thunderstorm, too.

Several sprites have been captured by both cameras, but around 20:40 UTC the system in Nydek recorded an odd sequence of emissions which was missed by the camera in Sopron. Flame-like emissions were shooting upwards. See the video! Comments are welcome.
