Clear at all three ground stations. Surface winds stay too high all evening. Sprite forecast promising. Waiting on local winds, which never died below 15 knots at 500'. Fairly nice day in Ottumwa.
Bad luck continues.
Poor visibility at ground sites and few to no sprites. Fantastic , bright sprite producer in Nebraska. Balloon bursts prior to launch of payload. Flight is aborted. 65 sprites are triangulated by at least two of the ground stations.
