00:00:00.600 --> 00:00:02.400
Roughly every 11 years, the

2
00:00:02.400 --> 00:00:03.633
Sun's magnetic field

3
00:00:03.633 --> 00:00:05.433
completely flips.

4
00:00:05.433 --> 00:00:06.966
This means the Sun's

5
00:00:06.966 --> 00:00:08.266
north and south magnetic

6
00:00:08.266 --> 00:00:09.800
poles switch places.

7
00:00:10.433 --> 00:00:11.833
Around the time of this flip

8
00:00:11.833 --> 00:00:12.966
solar activity

9
00:00:12.966 --> 00:00:14.966
gradually ramps up.

10
00:00:15.333 --> 00:00:16.133
The Sun will have

11
00:00:16.133 --> 00:00:17.233
more sunspots

12
00:00:17.233 --> 00:00:18.466
and solar eruptions

13
00:00:18.466 --> 00:00:19.833
like solar flares

14
00:00:19.833 --> 00:00:21.833
and coronal mass ejections.

15
00:00:22.333 --> 00:00:23.666
The peak of this activity

16
00:00:23.666 --> 00:00:25.666
is known as solar maximum.

17
00:00:26.100 --> 00:00:27.400
Solar maximum marks

18
00:00:27.400 --> 00:00:28.566
the halfway point of

19
00:00:28.566 --> 00:00:29.400
the solar cycle,

20
00:00:29.400 --> 00:00:30.766
and usually means a year

21
00:00:30.766 --> 00:00:33.000
or two of high solar activity.

22
00:00:33.600 --> 00:00:34.833
During this time,

23
00:00:34.833 --> 00:00:36.133
we might see more severe

24
00:00:36.133 --> 00:00:37.233
geomagnetic storms

25
00:00:37.233 --> 00:00:37.900
at Earth,

26
00:00:37.900 --> 00:00:39.100
which trigger aurora

27
00:00:39.100 --> 00:00:40.233
but also threaten

28
00:00:40.233 --> 00:00:41.533
our communications,

29
00:00:41.533 --> 00:00:43.533
satellites, and power grids.

30
00:00:44.300 --> 00:00:45.966
NASA scientists continue

31
00:00:45.966 --> 00:00:47.400
to study the solar cycle

32
00:00:47.400 --> 00:00:48.766
so we can better understand

33
00:00:48.766 --> 00:00:49.800
solar activity

34
00:00:49.800 --> 00:00:51.166
to protect our technology

35
00:00:51.166 --> 00:00:52.633
in space and on Earth.
