Meridional flow variations induced by magnetic cycles.
March 24, 2017

Surface observations indicate that the speed of the solar meridional circulation in the photosphere varies in anti-phase with the solar cycle.

Global 3D simulations of solar giant-cell convection.
March 24, 2017

Global 3D simulations of solar giant-cell convection have provided significant insight into the processes which yield the Sun’s observed differential rotation and cyclic dynamo action.

Space Weather Jan 2017 journal cover
February 16, 2017

In this NASA-led study, we report the concept of using near-real time observations from a coronagraph to provide early warning of a fast coronal mass ejection (CME) and the possible onset of a solar energetic particle (SEP) event.

MLSO Latest Images

H-alpha Disk and Limb

Currently, H-alpha images are obtained by the GONG network, operated by the National Solar Observatory .


CoMP Coronal Intensity

The COronal Multi-channel Polarimeter (CoMP) observes the Fe-XIII emission line at 1074.7 nm to measure the coronal magnetic field and obtain plasma density and motion in the low corona from ~1.03 to 1.5 solar radii.


K-Cor White Light Corona

Designed to study the formation and dynamics of coronal mass ejections and the evolution of the density structure of the low corona, K-Cor records the polarization brightness (pB).


K-Cor (radially graded filter)

K-Cor image with filter applied to maximize image contrast, especially in the outer field.
