February 14, 2017

On Sunday, February 12th, 2017, Prof. Egidio Landi Degl’Innocenti unexpectedly died of a heart attack in his home in Florence, Italy. Egidio had just returned from a scientific visit to the Instituto de Astrofísica de Canarias (IAC) in Spain, working with one of us (JTB). There he also spent his last birthday. He had just turned 72 on January 25th.

Publication Highlights

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.

Time evolution of two bipolar magnetic regions (BMRs)
January 9, 2017

We develop a three-dimensional kinematic self-sustaining model of the solar dynamo in which the poloidal field generation is from tilted bipolar sunspot pairs placed on the solar surface above regions of strong toroidal field by using the SpotMaker algorithm and then the transport of this poloida

Response functions to a horizontal 1 G magnetic field of the emergent Q linear scattering polarization
January 9, 2017

The linearly polarized solar limb spectrum caused by the absorption and scattering of anisotropic radiation has a very rich diagnostic potential, given its sensitivity to the thermal, dynamic and magnetic structure of the solar atmosphere.

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.
