Radio-loud CMEs from the disk center lacking shocks at 1 AU
N. Gopalswamy, P. Makela, S. Akiyama +4
A coronal mass ejection (CME) associated with a type II burst and originating close to the center of the solar disk typically results in a shock at Earth in 2-3 days and hence can…
The Relationship Between the Expansion Speed and Radial Speed of CMEs Confirmed Using Quadrature Observations of the 2011 February 15 CME
Nat Gopalswamy, Pertti Mäkelä, Seiji Yashiro +1
It is difficult to measure the true speed of Earth-directed CMEs from a coronagraph located along the Sun-Earth line because of the occulting disk. However, the expansion speed (th…
Behavior of Solar Cycles 23 and 24 Revealed by Microwave Observations
N. Gopalswamy, S. Yashiro, P. Mäkelä +3
Using magnetic and microwave butterfly diagrams, we compare the behavior of solar polar regions to show that (i) the polar magnetic field and the microwave brightness temperature d…
