Remote Sensing of Inner Heliospheric Plasmas
Abstract
Solar disturbances produce major effects on the corona, the solar wind, the interplanetary medium, and the Earth along with its magnetosphere. New techniques have been developed under this grant for studying plasma disturbances in the inner heliosphere by remotely sensing them. These techniques have used data from the HELIOS spacecraft zodiacal light photometers, in situ data and a variety of other spacecraft and ground based instruments. The zodiacal light photometers on board the two HELIOS spacecraft (data coverage from 1974 to 1986) provided the first reliable information about the heliospheric masses and shapes of propagating disturbances. The investigations into the physics of the disturbances sensed by these techniques, and the ability to forecast them, have been underway during the contract. The data analyses have used YOHKOH spacecraft observations, Sacramento Peak Observatory and Mauna Loa (Mark III) coronagraph data to map solar surface features. In addition, interplanetary scintillation (IPS) data from the Cambridge, England, Nagoya, Japan, and Ooty, India radio telescopes plus ULYSSES and IMP in situ data have been used to determine present day conditions in the solar wind.
