A recheck of our computations and arguments confirm our recent inferences (Gokhale, 1996) about: (a) existence of variations of ~ 1 % in the Sun's spin angular momentum on time scales of planetary orbits, (b) coupling of Sun's internal MHD to the solar system dynamics through the inertial torque caused by the spin variations and (c) the possiblity that this coupling maintains, through resonance, torsional MHD oscillations responsible for solar activity. Some tasks for verification and utilization of the new inferences are listed.
We analyzed a group of type III radio bursts and a Hα flare from the Sun that were observed simultaneously on 2015 January 14. The radio observations were in the spectral mode over the frequency range 85–35 MHz, and ...
Solar coronal jets are frequently occurring collimated ejections of solar plasma,
originating from magnetically mixed polarity locations on the Sun of size
scale comparable to that of a supergranule. Many, if not most, ...

The Zeeman effect has been routinely used to image and quantify the solar photospheric magnetic field (B). Such a
direct measuring technique is not yet available for the corona (Lin et al. 2004). Since almost all ...
