Good start to TLE observation season in Central Europe
But the night of 18/19 June 2012 has turned into a sprite observing spree at Swider geophysical station (central Poland) which had good view above a large storm sweeping across the north of Poland and the Baltic Sea coast. At least eleven events were recorded between 22:30 and 01 UT and more were missed by the recording system. There were plenty of sprites of all shapes and possibly dancing sprites. There are some examples (please mind the uncertainty of the time displayed on images is likely to be up to 1s, more photo information: A. Odzimek)
A couple of hours earlier sprites were also observed from Nydek. The HRV satellite image with overplotted lightning locations, below, shows how the situation was unfolding at 18 UT (please note the full functionality of this product is only at daytime). Recent images at 3-hour intervals are available from here.
