In summer of 2015, a team of scientists and engineers from the High Altitude Observatory successfully completed a Critical Design Review (CDR) for the Visible Spectro-Polarimeter (ViSP).
On 21 August 2017 a total solar eclipse will pass across the continental United States, from Oregon on the west coast to South Carolina on the east. The eclipse will be a phenomenal experience for the millions of people who see it, but it also offers a unique opportunity to conduct scientific research of the solar atmosphere.
Approximating a model’s “true” state by applying Kalman filtering to solar cycles, a technique first developed in the 1950s and 1960s to help Apollo 11 settle safely on the Moon.
Recent work on historical recurrent geomagnetic activity and the peculiarity of the recent solar-cycle minimum, was chosen by the editors of AGU journals for special highlight.
New observational work provides more information about the evolution of the Sun's interior and origins of its enigmatic 11(-ish) solar cycle. The research potentially opens the door to improved forecasting of decadal-scale solar variability.
