Solar alert

Issued on 2022 Jul 19 0741 UTC

A shock can be observed in the solar wind parameters about 18 July 20:33UT. The value of the total magnetic field increased from 8 to 13nT, the solar wind speed from 410 to 442 km/s and the density from 3 to 8 ppcc. This could had been an early arrival of the CME associated with a filament eruption on July 15, which was expected late 19 July.
