SES-14 communications satellite
January 30, 2018

The NASA Global-scale Observations of the Limb and Disk (GOLD) mission was launched into orbit on January 25, 2018 as a commercially hosted payload on the SES-14 communications satellite. The satellite was launched on an Ariane 5 rocket from the Guiana Space Centre in Kourou, French Guiana. There were anxious moments following lift-off when mission control lost contact with the satellite.

The McIntosh Archive project gets double notice: it's the subject of a recent highlight by EOS spotlight, which profiles a feature article for the journal Space Weather by Webb et al. and again it is presented in graphic form, by HAO's Don Kolinski, appearing on the cover of Space Weather—the McIntosh Archive "snake" stackplot of Solar Cycle 23.

Gravity wave drag anomaly
March 16, 2018

Whole Atmosphere Community Climate Model (WACCM) simulations are used to investigate the short-term (30-day) temporal variability in the mid- and high-latitude Southern Hemisphere mesosphere.

Comparison of measured to modeled global total electron content
March 13, 2018

Solomon & Qian show that solar minima are not all the same, and may have implications for understanding the Sun during the extended periods of very low activity known as “grand minima” that have sometimes occurred in the past, the best known of which was the Maunder Minimum during 1650–1700.

Longitudinal structures of zonal winds
March 1, 2018

In this work, Kedeng Zhang, Wenbin Wang and others, investigate the longitudinal patterns of thermospheric zonal winds (~400 km) and their seasonal and solar activity dependence.

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 a normalized radially graded filter (nrgf) to maximize image contrast, especially in the outer field.

These data are ideal for measuring positions of coronal structures such as CMEs and helmet streamers.
