The flux of cosmic rays (CR) in the heliosphere is subjected to remarkable time variations caused by the 11-year cycle of solar activity.
To study this effect, we have developed a web application (Heliophysics Virtual Observatory) that collects real-time data on solar activity, interplanetary plasma and charged radiation from several space missions or observatories.
As we will show, our application can be used to visualize, manipulate, and download updated data on sunspots, heliospheric magnetic fields, solar wind, and neutron monitors counting rates.
A nowcasting for the energy spectra of CRs near-Earth is also provided, using calculations and real-time neutron monitor data as input. Data are daily updated from databases listed in Resources section.
