On October 28, 2021, NOAA's GOES satellites watched the Sun as it unleashed
 a powerful solar flare.

2
00:00:13,233 --> 00:00:24,866
GOES East captured the event with its Solar Ultraviolet Imager.

3
00:00:28,166 --> 00:00:35,466
The flare produced an aurora that was visible in parts of the continental United States

4
00:00:35,466 --> 00:00:45,666
Meanwhile, JPSS satellites captured nighttime images of the 
aurora with the VIIRS Day-Night band.

5
00:00:48,566 --> 00:00:58,166
The Sun goes through a cycle of incresaing and decreasing activity that lasts around 11 years.

6
00:00:58,166 --> 00:01:04,900
The solar minimum, where it was least active, occurred in December of 2019.

7
00:01:04,900 --> 00:01:12,766
This means the Sun's activity has been ramping up and should peak around 2025.

8
00:01:13,133 --> 00:01:20,066
As the Sun reaches solar maximum, there will be more geomagnetic activity,
increasing the chance for stronger solar storms.

9
00:01:20,066 --> 00:01:25,666
After this peak, activity will decrease, and a new cycle will begin.

10
00:01:25,666 --> 00:01:36,533
NOAA's GOES satellites help monitor the activity of the Sun
 and when solar flares or coronal mass ejections occur.

11
00:01:36,533 --> 00:01:42,566
While flares can trigger spectacular shows of dancing lights,

12
00:01:42,566 --> 00:01:48,200
solar storms also have the potential to disrupt satellite communications and GPS signals.

13
00:01:48,200 --> 00:01:56,333
As Solar Cycle 25 moves toward the solar maximum, 
NOAA's GOES satellites will continue to monitor the Sun's activity.
