Study of solar activities associated with a Halo CME on 17 Feb 2023 event.

• A front side fast and wide Coronal Mass Ejection (CME) event propagated on February 17, 2023, is analysed. • The solar X-ray flare emission associated with this event is very intensive (X2.3). • The Type II radio emission generated in the wavelength range of 25 MHz – 180 kHz represents a Mkm Type II radio burst. • The kind of IP shock observed in the current study is a fast and forward type event. • ICME is a pure magnetic cloud type event. In the present work, propagation of an earth directed fast and wide Coronal Mass Ejection event on 17 February 2023 is studied in detail. The complex magnetic configuration in the Active Region (AR) 13229 at N25E64 caused an intensive X2.3 flare with a peak at 19:38 UT. It is followed by a massive halo CME event observed in the LASCO C3 coronagraph with a linear speed of 930 km/s and shock speed of 1300 km/s. A low frequency Type II emission was detected in the frequency range 10 MHz – 180 kHz during 20:30 UT-04:45 UT on 18 Feb 2023 by space borne Wind/WAVES instrument. From the OMNI data, the IP shock and the ICME reached earth's magnetosphere on 20 Feb 2023. A fast forward type shock was observed using OMNI high resolution data. The IP shock and ICME affected the Galactic Cosmic ray (GCR) detection. This event caused large magnetic turbulences in sheath region caused a major geomagnetic storm (∼-100 nT).
