00:00:02,302 --> 00:00:05,939
On October 22, 2024, NOAA satellites unveiled the first images from the

2
00:00:05,939 --> 00:00:09,409
Compact Coronagraph, or CCOR-1.

3
00:00:09,409 --> 00:00:13,613
CCOR-1 is NOAA’s first coronagraph. 

4
00:00:13,613 --> 00:00:18,318
It was launched onboard GOES-19 on June 25, 2024.

5
00:00:18,518 --> 00:00:23,957
CCOR-1 monitors the corona to forecast coronal mass ejections (CMEs),

6
00:00:23,957 --> 00:00:27,994
large expulsions of plasma and magnetic fields from the sun that can

7
00:00:27,994 --> 00:00:31,431
produce space weather impacts on Earth.

8
00:00:32,699 --> 00:00:36,736
CMEs can cause geomagnetic storms and other types of space weather

9
00:00:36,736 --> 00:00:41,241
that can affect satellites, communications and navigation systems,
power grids, and astronaut safety.

10
00:00:46,312 --> 00:00:50,150
While GOES-19 is still undergoing post-launch testing and checkout of

11
00:00:50,150 --> 00:00:53,453
its instruments and other systems, its solar instruments have observed 

12
00:00:53,453 --> 00:00:55,889
several phenomena, including large CMEs.

13
00:00:58,425 --> 00:01:02,462
These CMEs gave CCOR-1 the opportunity to view strong solar activity

14
00:01:02,462 --> 00:01:06,466
in addition to the sun’s more usual streamers
and other bright structures.

15
00:01:08,401 --> 00:01:12,639
In these events, the light came from solar plasma traveling outward

16
00:01:12,639 --> 00:01:16,810
together with these structures.

17
00:01:18,078 --> 00:01:21,748
On October 24, CCOR-1 and the Solar Ultraviolet Imager (SUVI),

18
00:01:21,748 --> 00:01:25,452
another solar instrument on GOES-19, viewed another CME.

19
00:01:26,820 --> 00:01:30,423
SUVI observes the sun in extreme ultraviolet wavelengths to capture

20
00:01:30,423 --> 00:01:34,194
phenomena like activity in sun spots, solar flares and eruptions of

21
00:01:34,194 --> 00:01:38,031
solar filaments that may lead to CMEs.

22
00:01:38,898 --> 00:01:44,104
These observations help scientists predict the severity of geomagnetic

23
00:01:44,104 --> 00:01:49,976
storms and issue warnings to minimize potential disruptions on Earth.

24
00:01:53,113 --> 00:01:57,383
Forecasters at NOAA’s Space Weather Prediction Center will use data

25
00:01:57,383 --> 00:02:01,754
from these instruments to improve the accuracy of forecasts and issue

26
00:02:01,754 --> 00:02:05,992
early warnings to protect vital infrastructure
from space weather threats.
