Coronal

This is the first time that a global map of the coronal magnetic field has been obtained through actual coronal observations, thus marking a leap towards solving the problem of coronal magnetic field measurements.

Loops of magnetic flux well-up from the solar body and fill with hot solar plasma. citation Due to the heightened magnetic activity in these coronal loop regions, coronal loops can often be the precursor to solar flares and coronal mass ejections (CMEs).

Coronal heating problem A new visualisation technique can provide clues to the coronal heating problem.

Coronal seismology main Coronal seismology is a new way of studying the plasma of the solar corona with the use of magnetohydrodynamic (MHD) waves.

The high temperature of Capella's corona as obtained from the first coronal X-ray spectrum of Capella using HEAO 1 required magnetic confinement unless it was a free-flowing coronal wind.

Also known as a coronal hole, it just means there’s a large dark area in the atmosphere that is cooler than its surroundings.

Data from RHESSI provided vital clues about solar flares and their associated coronal mass ejections.

The space weather phenomena has been triggered by a "coronal hole" in the outer layer of the Sun's atmosphere - the second to manifest in the last week.

This week, multiple coronal mass ejections (CMEs) were emitted by the sun and traveled at high speeds towards Earth, impacting our planet's magnetic field and resulting in auroras.

Last week, the solar storm was predicted by the US National Oceanic and Atmospheric Administration (NOAA), which detected a series of solar flares and coronal mass ejections – massive bursts of plasma and magnetic fields from the sun’s corona.

NOAA's Space Weather Prediction Center reports that they have issued a G3 Geomagnetic Storm Watch for December 31, due to the anticipated arrival of a coronal mass ejection exploded from the Sun over the weekend.

The orbiter, which reportedly cost $48 million, will study coronal mass ejections, a periodic phenomenon that sees huge discharges of plasma and magnetic energy from the Sun's atmosphere.

They're particularly interested to learn why the corona is hotter than the surface of the sun, and also want to better understand coronal mass ejections, eruptions of billions of tons of plasma with magnetic fields out into space.

This clip shows a coronal mass ejection which erupted from AR11158 on its way to Earth, moving outwards in LASCO c2 and c3 field of view.

Today, the Inouye Solar Telescope is the most advanced facility designed to study the corona, and has made a crucial first step in resolving these mysteries by producing its first coronal magnetic field maps – the most detailed to date.

Coronal holes are dark spots visible on the Sun's surface where the Sun's corona is colder and less dense.

Sun's coronal holes are about to release solar winds towards Earth: How will that affect us?
