Venus in the corona

A Rare Transit of Venus Across the Sun

The K-Cor 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. Sky & Telescope describes the movie captured by Alfred de Wijn (High Altitude Observatory, NCAR) and Gunther Können (Royal Netherlands Meteorological Institute).

Rosetta Stone Eclipse Campaign

HAO scientists observed the August 21st total eclipse with a suite of three instruments with financial assistance provided by NASA. The experiments were intended to learn about the magnetic and thermal structure of the solar corona with the goal of understanding how the Sun generates weather in space.

Annie Maunder, A Pioneer of Solar Astronomy

If you have visited the High Altitude Observatory (HAO) at NCAR in Boulder, CO, you may recall seeing the Maunder’s original butterfly diagram. The chart resembles three butterflies traveling west. Drawn by Annie S.D. Maunder and E. Walter Maunder, it demonstrated for the first time the movement of sunspot emergence from the poles toward the equator over the sun's 11-year cycle.
