HAO Sun Earth Lab

HAO's K-Cor coronagraph instrument at Mauna Loa Solar Observatory captured a rare close approach of Venus to the Sun as seen from Earth. Venus can be seen as a small black dot above the north pole as it transits the faint solar corona in these images of polarized white light.

Mauna Loa Solar Observatory observer Allen Stueben along with @whearobotics kids are producing Personal Protective Equipment with 3D printers, while wife Mary makes cloth masks. Great job Stuebens, thanks for helping the community! @somegoodnews www2.hao.ucar.edu/blog/hao-b…

Michael Knölker, engaged as always, questions Oskar von der Lühe (right), at the symposium held in his honor at the NCAR Mesa Laboratory.

The HAO-built Visual Spectro-Polarimeter (ViSP) was successfully installed at the @NSF and @NatSolarObs DKIST over the course of five weeks during two visits by HAO scientists. It measures polarized light from the Sun, improving our #2020SolarVision!
