Scientists from the Indian Institute of Astrophysics (IIA) through their latest study have given a clearer picture of how the sun’s magnetic field influences the interplanetary magnetic space which is the primary driver of space weather.
According to the Department of Science and Technology, scientists now are one step closer to identifying the source of the Solar Mean Magnetic Field (SMMF), which is the mean value of the line-of-sight (LOS) component of the solar vector magnetic field averaged over the visible hemisphere as well as its relationship with Interplanetary Magnetic Field (IMF).
The sun contains the corona (the outer shell of the sun’s atmosphere), the photosphere (the visible surface), and the chromosphere (near-transparent layer, just above the photosphere) with magnetic field generated by electrical currents acting as a magnetic dynamo inside the sun. These electrical currents are generated by the flow of hot, ionised gases in the sun’s convection zone.
