**Artemis** is a software designed to assist **radio frequency (RF) signal identification and storage**. It simplifies real-time spectrum analysis by leveraging one of the most extensive and community-driven databases, containing nearly **500 recognized signals**. This comprehensive software solution allows users to collect RF signals with specific parameters such as frequency, bandwidth, modulation, etc. Users can also store spectrum waterfalls, audio samples, and all types of documents for future reference. Artemis provides a robust platform to manage a wide range of RF data with precision and ease. **Artemis** is a software designed to assist **radio frequency (RF) signal identification and storage**.

## 1. Kp Index ## 1. Kp Index
The **K index** is a number (from 0 to 9) that shows how much Earth's magnetic field is disturbed. A K index of 1 means things are calm, while a K index of 5 or higher indicates a geomagnetic storm. These disturbances are measured with magnetometers that track changes in Earth's magnetic field every three hours. The K itself comes from a German word "Kennziffer" meaning "characteristic digit". To get a big picture of what's happening around the world, an official planetary **Kp index** is calculated. This is done by averaging the K indices from a special network of 13 geomagnetic observatories located around the globe at mid-latitudes.

## 2. A Index ## 2. A Index
The **A index** represents the three-hourly equivalent amplitude of geomagnetic activity at a specific magnetometer station, derived from the station-specific K index. Due to the quasi-logarithmic nature of the K-scale in relation to magnetometer fluctuations, directly averaging a set of K indices is not really meaningful. Instead each K is converted back into a linear scale. The **Ap index** is determined by averaging the eight daily A values, providing a measure of geomagnetic activity for a specific day. Days with higher levels of geomagnetic activity correspond to higher daily Ap values.
