The CH stream
Quoting: Da fuq the coronal hole winds are due to hit in a few days SOLAR WIND: A stream of solar wind blowing from a southern coronal hole on the sun is expected to brush past Earth's magnetic field on May 23-24. NOAA forecasters estimate a 30% chance that the contact will spark polar geomagnetic storms [ link to spaceweather.com] this CH wind will be arriving just before the CME from todays event, paving the path so to speak because of this, I would expect this CME to cause a bit more of a stir on earths magnetosphere than it would have otherwise Is There Any Evident Effect of Coronal Holes on Gradual Solar Energetic Particle Events? [ link to iopscience.iop.org] Solar energetic particle (SEP) events are one of the most important processes in space weather. Generally, SEP events have two classes: one is impulsive and the other is gradual (Cane et al. 1986; Reames 1999; Kallenrode 2003). The energetic particles in impulsive events usually come from the sites where flares occur. Rapid release of magnetic energy through magnetic field reconnections produces them. The particles in gradual events are considered to be generated at coronal/interplanetary shocks driven by fast coronal mass ejections (CMEs; e.g., Reames 1999). Statistically, gradual SEP events are larger and longer than the impulsive events. Mixed SEP events may also exist (e.g., Cane et al. 2003), in which there are both flare and shock particle components Both the fast and slow solar wind can be interrupted by large, fast-moving bursts of plasma called interplanetary coronal mass ejections, or ICMEs. ICMEs are the interplanetary manifestation of solar coronal mass ejections, which are caused by release of magnetic energy at the Sun. CMEs are often called "solar storms" or "space storms" in the popular media. They are sometimes, but not always, associated with solar flares, which are another manifestation of magnetic energy release at the Sun. ICMEs cause shock waves in the thin plasma of the heliosphere, launching electromagnetic waves and accelerating particles (mostly protons and electrons) to form showers of ionizing radiation that precede the CME [ link to en.wikipedia.org] SO the coronal hole streams end up catching up with say a cme or slow moving stream of solar particles and they colide causing them to bunch up,causing a shock when it hits and tacking longer to absorb into our shield? close or miles off? close the SEP event (solar energetic protons) that we are having right now breaks down the ionosphere, then the fast CH winds will intertwined with the CME that's incoming, (mix that with the parker spiral) and they all bunch up so to speak, while enrout in space and arrive together and make impact with a weaker magnetosphere (weaker because of the SEP event) the slower solar winds we are seeing right now are a type of 'tsunami' type of effect that we have seen and talked about in here before when there was a larger CME with a proton event. kinda like the sucking out before it comes in AH thanks
