What is planetary AP?
The Ap index is a measure of the general level of geomagnetic activity over the globe for a given (UT) day. …
What is my Kp-index?
The Kp-index is the global geomagnetic activity index that is based on 3-hour measurements from ground-based magnetometers around the world. The Kp-index ranges from 0 to 9 where a value of 0 means that there is very little geomagnetic activity and a value of 9 means extreme geomagnetic storming.
What is Aurora Kp-index?
Impress Your Friends, Predict the (Space) Weather 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.
How does Kp-index affect drones?
Based on this scale, many drone or remote pilots will not fly if the Kp-index reaches 4. Severe impacts increase the level of error and lead to risky flying. With a high disturbance, the GPS radio frequency are disrupted and the satellites will lose the critical lock necessary for intelligent flight.
What does the minimum Kp-index number need to be to show an aurora light in the sky?
Just remember the Kiruna K index jumping to 5 (typically meaning nice aurora) whereas the global average was only 2! You typically need more powerful storms corresponding to a Kp of minimum 5 to start seeing some aurora on the horizon at lower geomagnetic latitudes in the sub-auroral zone.
What is a good solar flux index?
For best conditions, the solar flux should remain above about 150 for a few days with the K index below 2.
Can you see aurora KP 4?
Kp 4 – Active – Bright, constant and dynamic northern lights visible. More colours start to appear. Kp 5 – Minor storm – Bright, constant and colourful aurora display, red and purple colours appear.
Can you see Aurora KP 4?
What is high Kp index?
There are many ways to represent geomagnetic activity. One of these is the Kp index which ranks the variations in geomagnetic activity from 0 to 9, in 3-hour intervals. The larger the Kp index is, the stronger the storm and the further south the northern lights will be visible.
What does a Kp index of 4 mean?
Kp 4 – Active – Bright, constant and dynamic northern lights visible. More colours start to appear. Kp 5 – Minor storm – Bright, constant and colourful aurora display, red and purple colours appear. Aurora coronae likely. Kp 6 – Moderate storm – Bright, dynamic and colourful aurora display.
How is the planetary Kp index derived from?
The planetary Kp-index is a globally averaged indicator of the worldwide level of geomagnetic activity. The official Kp index is derived by calculating a weighted average of K-indices from a predetermined network of geomagnetic observatories, the official Kp network.
How is the AP Index related to geomagnetic activity?
The Ap-index The Ap-index provides a daily average level for geomagnetic activity. Because of the non-linear relationship of the K-scale to magnetometer fluctuations, it is not meaningful to take the average of a set of K-indices. Instead, every 3-hour K-value will be converted back into a linear scale called the a-index.
How is the AP Index of a day determined?
Instead, every 3-hour K-value will be converted back into a linear scale called the a-index. The average from 8 daily a-values gives us the Ap-index of a certain day. The Ap-index is thus a geomagnetic activity index where days with high levels of geomagnetic activity have a higher daily Ap-value. How do you determine the Ap-index?
How is the AP Index related to the Kp index?
This planetary index is designed to measure solar particle radiation by its magnetic effects. The 3-hourly ap (equivalent range) index is derived from the Kp index as follows:
