X-ray Aura Analysis of the Solar Radio Burst Interfering with Navigation Signal Events on November 4, 2015

Solar radio burst event (SRB) is an optional factor for wireless communications especially satellites navigation communications. The peak flux of the SRB event in 4th November reached 5 800 SFU (Solar Flux Unit) in 1 415 MHz. During this event, the GPS receivers in European and the Air navigation systems all suffered from stronge influences. In this paper, we analysed the relationship between X-ray flux variation and radio flux variation during this event. By comparing, the beginning time of X-ray flux upraising was 30 minutes earlier than radio flux. Furthermore, in this paper we discussed the background of phenomenon, the soft and hot X-rays correspond to hot and non-hot electron radiation, which is the physical condition that produces radio bursts that can cause such space weather events. The soft-to-hard process of X-rays can offer an effective early alarming method for this kind of space weather events.
