CHALLENGES OF THE XXI CENTURY" NUR-SULTAN, KAZAKHSTAN, JULY 2019 374 Figure 1. The last year solar flare on 6th September at 11.53-12.10 UT. It was able to shine huge amount of x-rays (X 9.3) and a delayed proton wind capable to disturb or even disrupt several GPS satellite and to lead also to huge geomagnetic storms and boreal lights. Figure 2. The 6 th September 2017 flare was able to shine huge amount of x-rays. "SCIENCE AND EDUCATION IN THE MODERN WORLD: CHALLENGES OF THE XXI CENTURY" NUR-SULTAN, KAZAKHSTAN, JULY 2019 375 Figure 3. DTEC and VTEC increase peak the during Solar flare for Tashkent GPS station. Figure 4. GOES time history of proton fluxes of 2017 September 4–7. To identify the anomalous values of Total Electron Content TEC we calculated differential TEC (dTEC). dTEC is obtained by subtracting monthly averaged diurnal vTEC from the values of observed vTEC at each epoch. Fig.3 shows that differential TEC and Vertical TEC increasing peak the during solar flare of September 2017. In Figure 4, where the proton time profiles are shown, the SEPs under consideration are marked by vertical arrows. These SEPs were caused by the following flares: M5.5 flare on September 4, soft X-ray peak time 20:33 UT, coordinates S06W12; X9.3 flare on September 6, 12:02, S09W38; X8.2 flare on September 10, 16:06, S09W85.
