| 报告摘要/Abstract： | |
| Forecasting the conditions at the near-Earth space environment (space weather) is the actual scientific and practical task and needs the reliable sources of initial data -- the synoptic maps of solar magnetic fields. To obtain such maps is one of the main purposes of the FMG instrument at ASOS space mission. In the talk it will be demonstrated that using synoptic maps from different observatories (GONG, Mitaka (NAOJ), WSO, SSO) gives significantly different results for the ambient solar wind speed near the Earth’s orbit. A comparison of the predicted (in the frames of the WSA model) and observed (on board ACE satellite) bulk speeds shows as a rule rather low correspondence. A new approach, which takes into account the magnetic field strength inside of coronal holes, allowing to achieve a better coincidence between calculated and empirical results, is suggested. | |

| Prof.Mikhail DEMIDOV is the Deputy Director for Science of the Institute of Solar-Terrestrial Physics of Siberian Branch of Russian Academy of Sciences, Irkutsk, Russia, and leads the Solar Physics department, which includes two optical observatories: Sayan Solar Observatory (SSO) and Baikal Astrophysical Observatory. Graduated from Astronomy Department Kazan State University. He is a Doctor of Physics and Mathematics Sciences after defending of the Doctor thesis with the title “High-Precision Polarimetry and Diagnostics of the Large-Scale Magnetic Fields of the Sun”. He was PI or the head of team of some international scientific projects (ISF, INTASS, PIFI), connected with study of solar magnetic fields in cooperation with scientists from Germany, Switzerland, Japan, and China. His researches are focused on Solar Physics, Solar Instrumentation, and Space Weather. | |
