Using three-dimensional magnetohydrodynamic (MHD) simulations, we investigate the eruption of coronal flux ropes underlying coronal streamers and the development of a prominence eruption.

The semidiurnal lunar and solar tides obtained from meteor radar measurements spanning from 2009 until 2013 observed at Davis (69°S) and Rio Grande (54°S) are presented and compared to the northern hemisphere at Andenes (69°N) and Juliusruh (54°N).
Thermospheric gravity waves in the bottomside F region have been proposed to play a key role in the generation of equatorial plasma bubbles (EPB). However, direct observations of such waves have been lacking.
Plain Language Summary or Abstract: Gravity wave forcing near the mesopause drives a summer-to-winter residual circulation in the mesosphere and a reversed, lower thermospheric winter-to-summer residual circulation.
Thermospheric temperature and density recovery during the 5 April 2010 geomagnetic storm has been investigated in this study.
