Michael Knoelker Symposium: From Solar Physics to Exoplanets

Wednesday, February 26, 2020 to Friday, February 28, 2020

This meeting celebrates Michael Knoelker’s original work on solar and stellar magnetism and seismology, as well as his major contributions to the High Altitude Observatory during his 15-year directorship, and his recent appointment to Senior Scientist Emeritus. Michael started his career with ground breaking work on magnetic flux concentrations in the solar photosphere. Michael Knoelker is known for his mentoring of young scientists, his collaborations on high-altitude, long-duration, balloon programs and his role as a Co-PI on the Daniel K. Inouye Solar Telescope (DKIST).

This symposium will focus on recent developments and future directions in solar physics, the solar-stellar connection, exoplanets and modeling of exoplanet atmospheres.

Registration and abstract submission are open.
Early registration ends January 31, 2020.

Workshop Location:

The workshop will be held at NCAR's Mesa Lab building, 1850 Table Mesa Drive, Boulder, CO, 80305, in the main seminar room. Parking is free.


Please see the detailed agenda. Beginning on 26 February 2020, the workshop will run from 9:00-5:00 Wednesday–Thursday and 9:00-12:15 Friday. The talks will be webcast at https://www.ucar.edu/live?room=mlseminar.


Morning & afternoon coffee/tea will be provided. Lunches on Wednesday/Thursday will be catered. There will be a cocktail reception at the Mesa Lab cafeteria on Thursday evening following the science talks. The ML cafeteria opens for breakfast at 7:30 am.


We have reserved a block of rooms at the Best Western Plus Boulder Inn (nearest to venue) at a rate of $114/night plus tax (wifi, breakfast, parking included). The block will be held until 24 Jan 2020. You will need a car or Uber to get to the venue from this hotel (attendees with space in a rental car or those wanting to share an Uber can gather in the hotel lobby and coordinate rides).
