1 00:00:00,030 --> 00:00:04,050 music throughout 2 00:00:04,070 --> 00:00:08,090 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. 29 00:01:52,800 --> 00:01:56,780 Join the search for STEVE at www.aurorasaurus.org 30 00:01:56,800 --> 00:02:00,790 tone 31 00:02:00,810 --> 00:02:04,790 tone 32 00:02:04,810 --> 00:02:08,820 beeping 33 00:02:08,840 --> 00:02:12,846 beeping
