Katelynn Greer at 2015 AGU meeting
October 20, 2016

Katelynn Greer is currently working as an Assistant Research Physicist at the Space Sciences Laboratory at the University of California- Berkeley, working with Tom Immel and Scott England. She studied at the University of Colorado at Boulder in the department of Aerospace Engineering Sciences where she earned her BS (2007) and MS (2009).

Delores Knipp and Geomagnetic Storms
October 6, 2016

In The Conversation newsletter, scientists Delores Knipp and Brett Carter explore the significance of severe geomagnetic storm events and their impact on communications technology through descriptive historical accounts.

September 27, 2016

If you have visited the High Altitude Observatory, you may recall seeing the Maunder’s original butterfly diagram. The chart resembles three butterflies traveling west. Drawn by Annie S.D. Maunder and E. Walter Maunder, it demonstrated for the first time the movement of sunspot emergence from the poles toward the equator over the sun's 11-year cycle.

Publication Highlights

Raw S082B image with wavelength scale
October 20, 2016

We study UV spectra obtained with the SO82-B slit spectrograph on board SKYLAB to estimate the fine structure splitting of the Cl-like 3p43d4D5/2 and 3p43d4D7/2 levels of Fe X.

Snapshots of poloidal field
October 10, 2016

The key elements of the Babcock-Leighton dynamos are the generation of poloidal field through decay and dispersal of tilted bipolar active regions and the generation of toroidal field through the observed differential rotation.

Average ionospheric potential and DMSP F-16 ion drift observations
October 4, 2016

This paper investigates a possible physical mechanism of the observed dayside high-latitude upper thermospheric wind using numerical simulations from the coupled magnetosphere-ionosphere-thermosphere (CMIT) model.

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.
