Observation of Alfven wave in ICME-HSS interaction region
Omkar Dhamane, Anil Raghav, Zubair Shaikh +7
The Alfvén wave (AW) is the most common fluctuation present within the emitted solar wind from the Sun. Moreover, the interaction between interplanetary coronal mass ejection (ICME…
Temporal Variations of the Three Geomagnetic Field Components at Colaba Observatory around the Carrington Storm in 1859
Hisashi Hayakawa, Heikki Nevanlinna, Séan P. Blake +3
The Carrington storm in 1859 September has been arguably identified as the greatest geomagnetic storm ever recorded. However, its exact magnitude and chronology remain controversia…
The intensity and evolution of the extreme storms in January 1938
Hisashi Hayakawa, Kentaro Hattori, Alexei A. Pevtsov +7
Major solar eruptions occasionally direct interplanetary coronal mass ejections (ICMEs) to Earth and cause significant geomagnetic storms and low-latitude aurorae. While single ext…
The Extreme Space Weather Event in 1903 October/November: An Outburst from the Quiet Sun
Hisashi Hayakawa, Paulo Ribeiro, José M. Vaquero +11
While the Sun is generally more eruptive during its maximum and declining phases, observational evidence shows certain cases of powerful solar eruptions during the quiet phase of t…
Understanding Forbush decrease drivers based on shock-only and CME-only models using global signature of February 14, 1978 event
Anil Raghav, Ankush Bhaskar, Ajay Lotekar +2
We have studied Forbush decrease (FD) event occurred on February 14, 1978 using 43 neutron monitor observatories to understand the global signature of FD. We have studied rigidity…
