SDO 2020 Science Workshop: A Decade of Discovery
by Ryan Milligan 25 Feb '20

25 Feb '20

The Solar Dynamics Observatory (SDO) invites you to the SDO 2020 Science Workshop: A Decade of Discovery, to be held October 12-16, 2020, at the Hyatt Regency in Vancouver, BC, Canada. All members of the science community are welcome and encouraged to attend. The ten years since the launch of SDO has seen many papers in wide ranges of science results from this mission. As Solar Cycle 25 begins its rise to maximum, we will get together to discuss what we learned about the Sun and anticipate what the new cycle will look like. The invited speakers who will introduce themed sessions spanning SDO‘s wide range of research topics are: Junwei Zhao: Subsurface Flows, the Dynamo, and the Solar Cycle Stan Solomon: Phun with Photons: Response of atmospheres to EUV variability Paulo Simoes: Short-term Solar Variability Aimee Norton: Magnetic Flux in the SDO Era: From Emergence to Eruption KD Leka: SDO for Space Weather: Science and Applications Dan Seaton: The SDO Corona and Beyond Patrick Antolin: Energy and Mass Transfer Between the Corona and the Chromosphere Xudong Sun: Vector Magnetic Field: Progress and Prospects There will also be one day of parallel mini-workshops and an EUV calibration workshop. Registration, abstract submission, and other information about SDO 2020 will be made available at http://sdo2020.lws-sdo-workshops.org/. The Hyatt Regency can be explored at https://www.hyatt.com/en-US/hotel/canada/hyatt-regency-vancouver/yvrrv We are assessing the need for childcare during this workshop. Please send your care requirements to William.D.Pesnell (at) NASA.gov.

RHESSI Nuggets in February 2020
by Hugh Hudson 23 Feb '20

23 Feb '20

No. 370: "The Temporal and Spatial Extension of Gamma-ray Emission from the Sun”, by Nat Gopalswamy. Sustained solar γ-rays and solar cosmic rays coincide. No. 371: "Hot Cusp-Shaped Confined Solar Flare,” by Aaron Hernandez-Perez. A major flare may have a prominent hot cusp without the help of any eruption. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can be found by searching for their SOLyyyy-mm-dd identifier from this home page.
