“[D]iscovery is already shedding new light on the ionosphere”

NPR: A New Form Of Northern Lights Discovered In Finland – By Amateur Sky Watchers.

“The group was discussing the phenomenon in the days after Palmroth’s book was published, when one member pointed out that the mysterious phenomenon was happening at that very moment, outside their windows.

So Palmroth suggested a way that the members might be able to help scientists investigate the phenomenon: by taking photographs of it from different locations around Finland, at the exact same time.

Two of the group’s photographers managed to capture pictures of the aurora at the exact same second, from locations 120 kilometers (75 miles) apart. That gave researchers in Palmroth’s group at the University of Helsinki what they needed to measure the aurora and locate it in near-Earth space.”
