A coronagraph instrument at the Mauna Loa Solar Observatory on Hawai’i is used by a team of two scientists to record the rare transit of Venus across the Sun's corona.

NASA released a story about the The Whole Heliosphere and Planetary Interactions (WHPI) campaign that took place in coordination with Parker Solar Probe’s fourth perihelion.
We re-examine a 50+ year-old problem of deep central reversals predicted for strong solar spectral lines, in contrast to the smaller reversals seen in observations.
We conducted numerical simulations to examine dayside thermosphere and ionosphere responses to concurrent solar flares and a geomagnetic storm during September 6th – September 11th, 2017, as well as the interplay of flare and storm effects.
In the context of the solar atmosphere, we re-examine the role of of neutral and ionized species in dissipating the ordered energy of intermediate-mode MHD waves into heat.
