First, some details on Magnetic Portals or what S0 occasionally calls the 'Earth Footprint' referring to the Sun-Earth Variable Magnetic Connection.
Since 2008 NASA has asserted that every 8 minutes, "A magnetic portal will open, linking Earth to the Sun 93 million miles away. Tons of high-energy particles may flow through the opening before it closes again...It's called a flux transfer event or 'FTE.'"
The article also outlines how FTE's form:
"On the dayside of Earth (the side closest to the sun), Earth's magnetic field presses against the sun's magnetic field. Approximately every eight minutes, the two fields briefly merge or "reconnect," forming a portal through which particles can flow. The portal takes the form of a magnetic cylinder about as wide as Earth.
The European Space Agency's fleet of four Cluster spacecraft and NASA's five THEMIS probes have flown through and surrounded these cylinders, measuring their dimensions and sensing the particles that shoot through."
