First Observation of Chromospheric Waves in a Sunspot by DKIST/ViSP
The first scientific paper using data from the Visible SpectroPolarimeter (ViSP) has been published. The Inouye Solar Telescope's ViSP reveals new insight into the magnetic properties of waves and shocks as observed as "umbral flashes" within a small sunspot.
ViSP was developed at HAO and this publication is co-authored by HAO scientists Roberto Casini, Alfred de Wijn, and Philip Judge.
2023 UCAR/NCAR Summer Program: Heliophysics
The Heliophysics Summer School is run by NASA's Living With a Star program and UCAR/CPAESS since 2007; focusing on the physics of space weather events.
Apply for this summer 2023—deadline is
3 March 2023, see website.
We regret that the Space Weather Summer School is not meeting in 2023, but we hope to resume in 2024.
Mary Hudson Named Associate Fellow of the American Institute of Aeronautics and Astronautics

The citation reads: For a lifetime of leading studies and understanding of the radiation environment of Earth’s magnetosphere and the implications for successful operations of space systems.
Hawaii's Mauna Loa Erupts after 38 years; Mauna Loa Solar Observatory temporarily closed
After 38 years, Hawaii's Mauna Loa erupted on Sunday 27 November 2022 at 11:30 PM local time. The eruption quickly filled the summit caldera forcing lava to spill and flow outward in an east and west direction. While the exact timing was a surprise, the eruption was anticipated due to recently felt earthquakes. Lava flows east of the Mauna Loa Solar Observatory (MLSO) have destroyed parts of the access road to the observatory and knocked out all power to the site. MLSO is not near any lava flows and not in any immediate danger.
