Liz MacDonald: People were out observing the aurora, and they started noticing something that was overhead

3
00:00:08.110 --> 00:00:12.090
as well, when they were seeing aurora far to the northern regions.

4
00:00:12.110 --> 00:00:16.110
It was unlike most aurora. Talked to the scientists,

5
00:00:16.130 --> 00:00:20.120
we didn't know what it was. And together,

6
00:00:20.140 --> 00:00:24.200
they said we will keep taking observations, and we will call it Steve

7
00:00:24.220 --> 00:00:28.210
in the meantime. Steve is mostly a very narrow purple arc

8
00:00:28.230 --> 00:00:32.260
and sometimes it has these little green features

9
00:00:32.280 --> 00:00:36.310
that go along with it as well that are kind of like waving fingers

10
00:00:36.330 --> 00:00:40.370
or a picket fence. That means that there's plasma physics

11
00:00:40.390 --> 00:00:44.390
happening up there to cause that light and to make these

12
00:00:44.410 --> 00:00:48.400
little discrete features that we don't understand yet.

13
00:00:48.420 --> 00:00:52.410
We now have some satellite observations from the ESA satellite

14
00:00:52.430 --> 00:00:56.450
called SWARM that show that Steve

15
00:00:56.470 --> 00:01:00.480
optically is associated with a very strong flow

16
00:01:00.500 --> 00:01:04.490
in the particles in the ionosphere, the upper level of our atmosphere.

17
00:01:04.510 --> 00:01:08.580
Steve is important for a number of reasons. It's really

18
00:01:08.600 --> 00:01:12.580
exciting that people armed with cameras

19
00:01:12.600 --> 00:01:16.600
all over the globe can capture something that we didn't fully understand

20
00:01:16.620 --> 00:01:20.640
and shed new light on that.

21
00:01:20.660 --> 00:01:24.690
It's also really exciting that this happens further to the south where there are more people.

22
00:01:24.710 --> 00:01:28.690
So, it might be a kind of aurora that more people can see than the usual kind.

23
00:01:28.710 --> 00:01:32.710
We are now able to look up at the sky and see

24
00:01:32.730 --> 00:01:36.710
things about the aurora and this sub-auroral region

25
00:01:36.730 --> 00:01:40.710
that we never understood before.

26
00:01:40.730 --> 00:01:44.720
We can correlate that with our traditional observations and lead to greater

27
00:01:44.740 --> 00:01:48.730
understanding.

28
00:01:48.750 --> 00:01:52.780
Thank you to the citizen scientists around the world who help us explore as one.
