The Theory of Alfven drag (Drell et al. in J Geophys Res 70: 3131-3145 1965; Anselmo and Farinella in Icarus, 58, 182-185 1983) is applied here to show that the existence of a possible solar ring structure at a radial distance of 0.02 AU (~4R &sun; , R &sun; = radius of the sun) predicted by earlier authors (Brecher et al. in Nature 282, 50-52 1979; Rawal in Bull. Astr. Soc. India 6, 92-95 1978, Moon Planets 24, 407-414 1981, Moon Planets 31, 175-182 1984, J Astrophys Astr 10, 257-259 1989) may not survive Alfven drag produced during even moderate solar magnetic storms which take place from time to time through the age of the sun, but a possible solar ring structure at a radial distance of 0.13 AU (~27R &sun; ) (Brecher et al. in Nature 282, 50-52 1979; Rawal in Bull. Astr. Soc. India 6, 92-95 1978, Moon Planets 24, 407-414 1981, Moon Planets 31, 175-182 1984, J Astrophys Astr 10, 257-259 1989) may survive intense Alfven drag produced during even strong magnetic storms of magnetic field value up to 1,000 G.
