In this report we give an overview of the Eurosprite observation
programme and present the results of the Eurosprite
2005 campaign. These campaigns search for occurrences of
transient luminous events, such as red sprites, above thunderstorms
in France, Spain, northern Italy, Switzerland and
southwestern Germany. Low-light video cameras are used
to register the events. Simultaneously, meteorological observations
and continuous recordings of electromagnetic emissions
in the VLF-ELF-ULF range and of infrasound are carried
out. During the Eurosprite 2005 campaign, two camera
systems were operated at two locations in southern France.
In total 64 sprite events were captured. Due to unfavourable
conditions, none of these were captured simultaneously at
both stations.
The campaigns constitute a long-term effort but have already
provided several new results, mainly concerning the
correlation between optical and non-optical means of sprite
detection. The campaigns will be extended into a global
sprite-watch partnership and in addition space-borne instruments
will be deployed.
