AI Technical Summary

Technical Problem

Existing solar flare warning information lacks information on the location of flares, making it difficult to accurately determine the occurrence of solar proton events and whether coronal mass ejections reach Earth, thus affecting the accuracy of space weather forecasts.

Method used

By acquiring the peak time of the flare, the full solar surface image, and the initial solar surface position of the solar active region, coordinate system transformation and pixel value calculation are performed to determine the location of the flare. Finally, flare warning information is generated by using a preset solar surface differential rotation formula and pixel threshold filtering.

Benefits of technology

This technology enables accurate location determination of flares during their occurrence, improving the accuracy and practicality of space weather forecasting and avoiding the lack of location information in existing technologies.

Abstract

The application discloses a flare occurrence position determination method and device, electronic equipment and computer medium. The method comprises the following steps: when it is determined that a flare occurs, a flare peak time, a full-disk image corresponding to the flare peak time and initial disk positions of each solar active region are obtained; according to the flare peak time and the initial disk positions of each solar active region, first disk positions of each solar active region corresponding to the flare peak time are determined; the first disk positions of each solar active region are subjected to coordinate system conversion, and pixel positions of each solar active region in the full-disk image are determined; according to the pixel positions of each solar active region and the full-disk image, first pixel values of regions in which each solar active region is located in the full-disk image are respectively calculated; and the first disk position of a solar active region corresponding to a maximum value is determined as the occurrence position of the flare. The application can accurately determine the occurrence position of the flare when the flare occurs.
