Interactive service of geoeffective phenomena

This work attempts to develop an online service for the specialists and amateurs interested in the problem of space weather forecasting. It is based on the scheme of the existing ``Observe the Sun'' service developed by the employees of the Kislovodsk Mountain Astronomical Station (KMAS) of the Central Astronomical Observatory of the Russian Academy of Sciences for rapid demonstration of current solar activity phenomena. At the first stage, we consider one of the geoeffective factors, the solar wind, for calculation of which there exist generally accepted models. The initial data are the observations of the photospheric magnetic field, regularly carried out at the KMAS. The coronal field at the source surface and the velocity field are calculated using the well-known potential field source surface (PFSS) and Wang–Sheeley–Arge (WSA) models. At the next stage, we plan to simulate the solar wind flow at a distance of up to 1 AU and evaluate its geoeffectiveness.
