Abstract :
A new instrument composed by a high speed camera, two high energy detectors, a E-field antenna and a VHF antenna were installed at the Eagle Nest tower (northeast of Spain) during summer 2011. With this equipment several lightning flashes to the tower and its vicinity have been observed. This paper presents two examples: the first was an upward negative leader triggered by a close cloud-to-ground flash and the second was an upward negative flash not associated with previous lightning activity. The paper also presents 3D mapping of leaders of two upward lightning.
