Upward streamer
An upward unconnected leader (or upward streamer as it is more commonly termed) is a positively charged channel of ionized air that rises from ground objects (like buildings, towers, trees or even the ground itself) towards a negatively charged downward-moving "stepped leader" from a storm cloud. When an upward leader "connects" with a downward leader, the lightning bolt we see occurs. It is possible to catch (in a photo) one or some of the upward leaders who "didn't make it" to connect with the downward one.
