In February 1972, the Astrophysical Journal published "Time Scales for Ca II Emission Decay, Rotational Braking, and Lithium Depletion" by Dr. Andrew Skumanich, a research scientist at the High Altitude Observatory (HAO) in Boulder, Colorado. The paper is one of the most impactful publications in the history of HAO, with ~1500 citations to date.

To celebrate the 50th anniversary of this publication, HAO will host an in-person conference on 15–18 February 2022, organized around the major themes of the paper: stellar activity, stellar rotation, and lithium depletion. Dr. Skumanich has confirmed his attendance, and he is expected to deliver the opening talk of the conference.

For planning purposes, we ask those who may be interested in attending to please pre-register. Participation is limited to a maximum of 340 people. If the space fills, precedence will be given to those who pre-register when the website opens for contributed talks and posters later this year. We hope to see you in Boulder!
