Today HAO begins a celebration of the work and achievements of former director and now Senior Scientist Emeritus Michael Knoelker with a symposium "From Solar Physics to Exoplanets" held in his honor. Info & Agenda: www2.hao.ucar.edu/MK-Symposium20… LIVE webcast: ucar.edu/live

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

Hey Northern Colorado: HAO scientists will be in Fort Collins tomorrow (Feb 29) at the Colorado State "Little Shop of Physics." Stop by our table to learn about solar magnetism, space weather, and more! lsop.colostate.edu

Every Friday at HAO Sun Earth Lab we have donuts and coffee with colleagues & visitors. Today we kept the tradition going with a virtual donuts on Google Hangouts. Definitely nice to see some familiar faces after a week at home.

Terminator Watch: The southern activity band definitely growing in strength and clarity - the band is lagging but definitely getting more pronounced. Both centered on +/- 30 degrees, but south has more spread. #Terminator2020

Mauna Loa Solar Observatory observer Allen Stueben along with WHEARobotics 3881 kids are producing Personal Protective Equipment with 3D printers, while wife Mary makes cloth masks. Great job Stuebens, thanks for helping the community! Some Good News www2.hao.ucar.edu/blog/hao-blog/…

Mausumi Dikpati presenting on how [Magnetic] Rossby Waves in the Sun's interior shape and drive space weather to our friends at NOAA Space Weather Prediction Center ! Awesome!!!! NSF National Center for Atmospheric Research

Almost 8 years ago exactly, Venus passed across the face of the Sun, in what would be the last Venus transit of our lifetimes. Yesterday we had a ‘near miss’, with Venus passing less than a solar radii above the Sun’s northern edge. (Image credit, MLSO K-Cor) 1/6

What time is it? Solar storm o'clock on the dot. Scientists have created an elegant Sun clock that shows that solar activity starts and stops on a much more precise schedule that many researchers thought. news.ucar.edu/132738/new-sun… Scott McIntosh Bob Leamon #AGUpubs Warwick Newsroom

Two astronomers captured the silhouette of Venus as it passed in front of the solar corona. buff.ly/2CSI07O

While a transit of Venus across the Sun's face is incredibly rare (the next is not due until 2117), the planet occasionally travels through the corona, as it did in early June. A coronagraph at NCAR's observatory on Hawaii captured the uncommon passage. skyandtelescope.org/astronomy-news…

Meet our new director, Holly Gilbert!

What on 🌎 is space weather? Join NCAR scientist Stan Solomon this Thursday for a talk about the physics and chemistry behind space weather, storms, and the aurora! Register today for the event on 11/19: …er-series-space-storms.eventbrite.com #spaceweather #NSFstories
