H alpha observations of a M5.4 flare taken in the active region NOAA 10646 with the Vacuum Tower Telescope at Observatorio del Teide, Tenerife, on July 13, 2004 are presented. The temporal evolution of the area of the flare and its morphological changes are investigated and discussed. Simultaneous observations of the flare in EUV lines taken with CDS/SOHO instrument are shown and additional data from GOES-10 instrument are compared.
