תקציר

Optical observations of 66 sprites, using a calibrated commercial CCD camera, were conducted in 2009-2010 and 2010-2011 winter seasons as part of the ILAN (Imaging of Lightning And Nocturnal flashes) campaign in the vicinity of Israel and the eastern Mediterranean. We looked for correlations between the properties of parent lightning (specifically, the charge moment change; CMC) to the properties of column sprites, such as the measured radiance, the length and the number of column elements in each sprite event. The brightness of sprites positively correlates with the CMC (0.7) and so does the length of sprite elements (0.83). These results are in agreement with previous studies, and support the QE model of sprite generation.

Funding Information:
The ILAN sprite campaigns are dedicated to the memory of the first Israeli astronaut Col. Ilan Ramon, lost with his crew members on board the Space Shuttle Columbia in February 2003. This work was supported by the Research Authority of the Open University of Israel, and by the Israeli Science Foundation grant 117/09 .
