The fastest solar wind in 50 years.The fastest solar wind in 50 years Even though there were no spacecraft aloft during much of the last 50 years to measure the sun's continuous outpouring of ionized particles, or solar wind, scientists have established the date and rate of the highest solar wind over the past half-century: 7.8 million kilometers per second on Aug. 4, 1972. E. W. Cliver, of the geophysics laboratory at Hanscom Air Force Base Hanscom Air Force Base, initially and briefly designated Bedford Army Air Base, is a U.S. Air Force facility in Bedford, Massachusetts. It is the headquarters of the Electronic Systems Center (ESC), one of the product centers of the Air Force Materiel Command (AFMC). , Mass., and J. Feynman and H. B.

Jet Propulsion Laboratory (JPL) is a NASA research center located in the cities of Pasadena and La Cañada Flintridge, near Los Angeles, California, USA. in Pasadena, Calif., calculated this record by comparing ground-measured delays between solar flares and the turbulence (geomagnetic storms) they cause in Earth's magnetic field Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with one pole near the north pole (see Magnetic North Pole) and the other near the geographic south pole (see Magnetic South Pole). . The researchers report the finding in the Oct. 1 JOURNAL OF GEOPHYSICAL RESEARCH Journal of Geophysical Research is a publication of the American Geophysical Union. JGR was formerly titled Terrestrial Magnetism from its founding by the AGU's president Louis A. . |
