A High-speed streams (HSSs) catalogue was issued for Solar Cycle 24 (SC24) by Besliu-Ionescu et al. (2022) and is available online at http://www.geodin.ro/varsiti/. Such a catalogue is extremely valuable as it help researchers understand the solar wind state close to the Earth from the point of view of the speed state at a given moment.
HSSs in the solar wind are an important physical driver of space weather. Along with other solar-driven phenomena, they may seriously impact various aspects of our increasingly sophisticated technological lives.
The HSS catalogue for SC24 considers only HSSs generated by coronal holes. These HSSs are recurrent, co-rotating streams with an apparent tendency to occur every 27 days. There are also non-recurrent HSSs produced by certain eruptive solar phenomena such as flares, coronal mass ejections, sudden disappearing filaments, or eruptive prominences.
The catalogue distinctively shows HSS basic properties, their sources, parameters of the interplanetary magnetic field, and various properties related to the associated geomagnetic storms.
