Recent Solar Wind Observations The solar wind plays a vital role
in transfering the effects of solar activity to the Earth's
space environment. The density, speed, pressure, and temperature
of the solar wind upstream of the Earth as well as the magnitude
and direction of the interplanetary magnetic field all influence
the impact of solar disturbances on the Earth's magnetosphere,
ionosphere The clock dial plots below, provided by Rice
University, show the values of solar wind parameters upstream of
the Earth at L1. Last Measurement (at Sun-Earth L1 Point):
