We caught 19 Sprites, 1 Halo, and 1 Sprite + Halo during a Cyprus low cyclone. The synoptic map in the area is dominated by upper trough from East Europe (500hp) and a low pressure cyclone in the surface (850hp). CAPE values were 300-400 J/Kg and Vertical wind was 28-30 hp/hour.
We observed during all the weekend. There was a storm (Cyprus Low) all over the area. Sadly in the first night 21-22 Nov we were covered with cloud, despite of it, we caught several meteors between the gaps. On the second night 22-23 Nov the storm died in our region and was located on the northern part of Cyprus and the coast of Turkey. The CAPE values were quite low and the flash rate was low too. We caught 8 meteors. On the third night, the storm shifted to Iskenderun bay - the north-east part of the Mediterranean. The flash rate increased and we were on the edge of our observation range. we caught 7 meteors during the night and one sprite. The distance to the area is more then 400km.
During the night of the 13-14 of November we conducted night observation from Jerusalem. we observed 20 meteors and 1 sprite. It seems that the parent cell cloud top wasn't significantly high based on satellite image, but it seems that there was enough stratified region to accumulate positive charge.
attached the sprite image and the satellite image.
In continue to the results of the Tel Aviv site during the night of the 12-13 of november, we attach the image of sprite capruted from Jerusalem. The distance to the sprite is estimated to be 150km bearing 035 from Jeruslaem.
We caught 2 new sprites in the night of 12-13.11.2008. The storm can be seen in the attached synoptic map. The sprites were caught from Tel-Aviv University. during the observation we used two cameras but sadly, the sprites were caught on the edge of the right camera, thus, the left camera with the "red filter" missed them. We caught an immpresive fireball. The meteor was caught on both cameras. thus analysed calculation can be made to understand what is the diffrence between the emission of the burning over all the visible wavelengthes to the emission from the meteor in the red filter camera(630-810 nm).
ILAN Science Team is an Israeli TLEs hunting project.
The sprite campaign began in 2005. Till now, we caught more then 100 TLEs (Sprites, Elves). Our research is focusing on Modeling, measuring and quantifying electromagnetic radiation produced by lightning associated with Transient Luminous Events (TLE's).
We have three stations:
* Tel Aviv Univeristy, Tel Aviv, Israel. * The Hebrew Univeristy, Jerusalem, Isreal. * Wise Observatory, Mitzpe Ramon, Israel.
