1Interplanetary consequences and geoeffectiveness of CME associated with major solar flare from NOAA AR 12673显示文摘In this reported work,we study a major X-class flare(X9.3) that arose from NOAA Active Region(AR) 12673 on 2017 September 6,from 11:53 UT to 12:10 UT in multi-wavelength views.This event also produced a fast coronal mass ejection(CME).NOAA AR 12673 emerged at S09 W30 on 2017 September6 and grew rapidly to a large AR.On 2017 September 9,the maximum area of this AR was 1060 millionth of the solar hemisphere.The group of sunspots disappeared over the west limb of the Sun(S09 W83) on September 10.It was a fast emerging flux region.The group of sunspots showed magnetic configuration category alpha-beta-gamma.We identified their earliest signatures of eruption in AIA 94A images with initialization and successive rapid growth from low coronal heights of hot channeled structures.On the other hand,the CME associated with this flare event triggered the intense Dst at 1 AU(–142 nT).We have acquired observations and analyze the reported event from the Sun’s surface,corona(source AR),interplanetary space and in-situ measurement near Earth.In addition,here we analyze the complex processes of CMECME interaction that have contributed a significant role to make the reported event so geoeffective.Shirsh Lata Soni Radhe Shyam Gupta Pyare Lala Verma 2020Research in Astronomy and Astrophysics2020,20,2:0
