What is a geomagnetic K-index of 4?
The Estimated 3-hour Planetary Kp-index
| Kp | G-scale | Geomagnetic latitude |
|---|---|---|
| 4 | G0 | 58.3° |
| 5 | G1 | 56.3° |
| 6 | G2 | 54.2° |
| 7 | G3 | 52.2° |
What scale is used to measure the strength of a solar storm?
The NOAA Geomagnetic Storm Scale indicates the severity of geomagnetic storms. It is denoted by a G followed by a number from 1 to 5, with 1 being a minor event, and 5 being an extreme event. Power systems: Weak power grid fluctuations can occur.
What is NOAA Kp index?
The planetary 3-hour-range index Kp is the mean standardized K-index from 13 geomagnetic observatories between 44 degrees and 60 degrees northern or southern geomagnetic latitude. The label ‘K’ comes from the German word ‘Kennziffer’ meaning ‘characteristic digit. ‘ The K-index was introduced by Julius Bartels in 1938.
What is geomagnetic K-index?
The K-index quantifies disturbances in the horizontal component of earth’s magnetic field with an integer in the range 0–9 with 1 being calm and 5 or more indicating a geomagnetic storm. It is derived from the maximum fluctuations of horizontal components observed on a magnetometer during a three-hour interval.
What is a good KP to see Northern Lights?
If the Kp is 5 or greater, the better your chances of seeing an aurora. You can check out the SWPC Estimated Planetary Kp graph to see what has been happening during the past few days. The red bars indicate a Kp higher than 4, which makes your odds of seeing an aurora greater.
What is a G1 G2 storm?
The National Weather Service’s Space Weather Prediction Center (SWPC) has issued a G1 (Minor) Geomagnetic Storm Watch for today and a G2 (Moderate) Geomagnetic Storm Watch for tomorrow. Geomagnetic storms are rated on a 1-5 scale, with 1 being the weakest and 5 having the most potential for damage.
What’s a G1 or G2 storm?
What is a X1 solar storm?
This flare is classified as an X1-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
What does KP 7 mean?
Strong storm
Kp 7 – Strong storm – Bright, dynamic and colourful aurorae. Visible in the southern sky. Aurora coronae very likely. Kp 8 – Severe storm – Bright, dynamic and colourful aurorae.
Can you see KP 4 aurora?
To do this, you’ll check an index called Kp, a number from 0–9, which is used to rate the global geomagnetic activity for a 3-hour period. If the Kp is 5 or greater, the better your chances of seeing an aurora. Bars in red have a Kp over 4, indicating a better chance of aurora activity.
Is higher Kp better for Northern Lights?
It’s impossible to predict the aurora accurately, but geomagnetic activity – measured by the ‘Kp index’ – indicates when the lights are most likely to appear. The higher the Kp index the better your chances. Ratings of 8 or above are very rare, and many of the photos included here were taken at low Kp numbers.
What is a G3 magnetic storm?
G3 (Strong) Geomagnetic Storm Conditions Reached with CME Arrival.
