Initiation, propagation and interplanetary consequences of geo-effective CME associated with major solar flare of solar cycle 24

In this reported work, we study a major X-class flare (X 9.3) that arise from active region NOAA 12673 on September 06, 2017, during 11:53 UT to 12:10 UT on multi-wavelength view. This event also produced a fast Coronal Mass Ejection. Active region NOAA 12673 emerged at S09W30 on September 06, 2017, and grew rapidly to a large active region. On 09 September 2017, its maximum area of this active region was 1060 millionth of the solar hemisphere. The group of Sunspot disappeared over the west limb of the Sun (S09W83) on 10 September. It was a fast emerging flux region. The group of Sunspot showed magnetic configuration category alpha-beta- gamma. We identified their earliest signatures of eruption in AIA 94 images with initialization and successive rapid growth from low coronal heights of hot channelled structures. On other hand the CME associated with this flare event gives rise the intense Dst at 1AU (-142nT). We have taken observation and analyse the reported event from the Sun surface; corona (source active region), interplanetary space and in-situ measurement at near Earth. In addition, we analyse here the complex processes of interaction of CME-CME that have contributed a significant role to make reported event such geo-effective. (author)
