Deriving the strength and direction of the three-dimensional (3D) magnetic field in the solar atmosphere is fundamental for understanding its dynamics. Volume information on the magnetic field mostly relies on photospheric and/or chromospheric surface vector magnetic fields.

Solar magnetic activity exhibits variations with periods between 1.5–4 years, the so-called quasi-biennial oscillations (QBOs), in addition to the well-known 11-year Schwabe cycles. The solar dynamo is thought to be the responsible mechanism for the generation of the QBOs.

Global-scale Observations of the Equatorial Ionization Anomaly

Monday, August 5, 2019

The NASA Global-scale Observations of the Limb and Disk (GOLD) ultraviolet spectrograph began imaging the Equatorial Ionization Anomaly (EIA), regions of the ionosphere with enhanced electron density north and south of the magnetic equator, in October 2018.

The second Miniature X-ray Solar Spectrometer (MinXSS-2) CubeSat builds on the success of MinXSS-1. The science instrument is more advanced – now capable of greater dynamic range with higher energy resolution.

Predictability of the mesosphere and lower thermosphere based on initialized hindcast experiments

Monday, July 15, 2019

The ability to predict conditions in Earth’s ionosphere and thermosphere is of increasing societal relevance due to the growing dependence on, for example, satellite based communications and navigation (e.g., GPS) systems.

What the Sudden Death of Solar Cycles Can Tell us About the Nature of the Solar Interior

140 year record of solar filaments
Monday, July 1, 2019

We observe the abrupt end of solar activity cycles at the Sun’s Equator by combining almost 140 years of observations from ground and space.
