Remote-Sensing of Solar Wind Speeds from IPS Observations at 140 and 327 MHz Using MEXART and STEL

摘要: Interplanetary scintillation (IPS) is used to probe solar wind speeds in the inner heliosphere by applying either of two generalized data-analysis techniques: model fitting power spectra (MFPS) from a single station, or cross-correlation functions (CCF) produced cross-correlating simultaneous IPS time series separate stations. The MEXican Array Radio Telescope (MEXART), observing at 140 MHz, starting use an MFPS technique. Here we report first successful speed determinations with observations MEXART. Three stations Solar-Terrestrial Environment Laboratory (STEL), 327 CCF, and technique also one these sites. We here analyze data MEXART antenna STEL obtain using station. were carried out radio source 3C48 during Solar Cycle 24. method describe tested comparing its obtained those CCF find that techniques generally agree within estimated errors.
