Introduction

Solar Soft X-ray flares accompanied by enhanced electromagnetic radiation and particle acceleration of particles in the ionosphere and space weather environment may cause A great influence. Solar soft X-ray flare monitoring space weather monitoring and early warning has become an important business. In order to quantitatively describe too The degree of strength of the male soft X-ray flare, the standard is formulated. Solar soft X-ray flares strength rating

1 Scope

This standard specifies the soft X-ray solar flares strength rating. This standard applies to the monitoring and early warning service solar soft X-ray flares.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Solar flares solarflare Local area solar atmosphere suddenly lightened active phenomena, often accompanied by enhanced electromagnetic radiation and particle emission. 2.2 Soft X-ray solar flares solarsoftX-rayflare Solar flares in soft X-ray band phenomenon occurred. 2.3 Soft X-ray intensity solar flares intensityofsolarsoftX-rayflare In the Earth's atmosphere, the astronomical units from the sun at a solar soft X-ray flares in 1 × 10-10m ~ 8 × 10-10m band Fan Around the peak flow of the electromagnetic radiation. Note 1. The symbol FX expressed in units of J/(m2 · s). Note 2. 1 astronomical unit = 149598000km. 3 solar soft X-ray flares strength rating 3.1 solar soft X-ray flare intensity according to traffic volume is divided into A, B, C, M, X five levels, see Table 1.
