The variabilities of the semidiurnal solar and lunar tides of the equatorial electrojet (EEJ) are investigated during the 2003, 2006, 2009 and 2013 major sudden stratospheric warming (SSW) events in this study.

The motions of small-scale magnetic flux elements in the solar photosphere can provide some measure of the Lagrangian properties of the convective flow.
Digital image sensors are ubiquitous in astronomical instrumentation and it is well known that they suffer from issues that must be corrected for data to be scientifically useful.
HD 81809 has one of the highest-quality activity cycles from the sample of stars synoptically observed in the Mount Wilson Observatory HK Project.
Peterson et al. (2015) developed an algorithm for estimating the electric field vector at any point above an electrified cloud from passive microwave observations.
