We report the observation of ELF and VLF signature of sprites recorded on\udthe low altitude satellite DEMETER during thunderstorm activity. At an\udaltitude of ~700 km, waves observed on the E-field spectrograms at\udmid-to-low latitudes during night time are mainly dominated by up-going 0+\udwhistlers. During the night of 20 July 2007 two sprites have been observed\udaround 20:10:08 UT from the observatory located on the top of the mountain\udŚnieżka in Poland (50°44'09" N, 15°44'21" E,\ud1603 m) and, ELF and VLF data have been recorded by the satellite at about\ud1200 km from the region of thunderstorm activity. During this event, the\udDEMETER instruments were switched in the burst mode and it was possible to\udregister the wave forms. It is shown that the two sprites have been\udtriggered by two intense +CG lightning strokes (100 kA) occurring during the\udsame millisecond but not at the same location. Despite the distance DEMETER\udhas recorded at the same time intense and unusual ELF and VLF emissions. It\udis shown that the whistler wave propagates from the thunderstorm regions in\udthe Earth-ionosphere guide and enters in the ionosphere below the satellite.\udThey last several tens of milliseconds and the intensity of the ELF waveform\udis close to 1 mV/m. A particularly intense proton whistler is also associated\udwith these emissions
