Allen Stueben, Mauna Loa observer and Associate Scientist II, recently attended two FIRST Robotics Competitions in Sydney, Australia, as one of the mentors for the WHEA (West Hawaii Explorations Academy) Sharkbots FIRST Robotics Team (team #3881.) Both events were held at the Sydney Olympic Park Quaycentre.

Most people have heard about tsunamis in the Earth’s oceans. Those occur when large masses of water get violently moved at the ocean floor, as a result of earthquakes or volcanic eruptions.

We investigate trends and solar irradiance effects in the mesosphere using the Whole Atmosphere Community Climate Model with eXtended thermosphere and ionosphere (WACCM‐X) and radar measurements of winds at Collm (51°N, 13°E), for the period of 1980–2014.

The period of September 6 – 11, 2017 was an active period in which multiple solar flares and a major geomagnetic storm occurred. The two largest flares, an X9.3 and an X8.2 flares, were a disk flare and a limb flare, respectively.

We present spectra and broad-band polarized light data from a suite of instruments deployed during the 21st August 2017 total solar eclipse. Our goals were to survey solar spectra at thermal infrared wavelengths during eclipse, and to test new technology for measuring polarized coronal light.

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.
