Celebrating A Solar Cycle of Discovery with SDO

You are Invited to Contribute your Solar Research to a Topical Collection of Solar Physics on “Celebrating A Solar Cycle of Discovery with SDO”

 

We solicit manuscripts on this general subject for inclusion in a Topical Collection of Solar Physics.  The deadline for submission of statements of interest (SOI) with a tentative title, abstract, author list, and three suggestions for referees, via e-mail to solar.cycle.with.sdo@gmail.com is 15 June 2021, and the nominal deadline for manuscript submission is 22 October 2021.

This Topical Collection is an outgrowth of the “SDO 2021 Science Workshop: A Solar Cycle of Discovery,” which was held as a series of virtual workshops 12 February – 15 April 2021 (http://sdo2021.lws-sdo-workshops.org). This Topical Collection is not a conference proceeding, and it is not limited to research presented at the workshop. All submissions must be complete original papers that meet the regular quality requirements of the Journal. The Topical Collection will start off with several invited reviews to summarize the subject and frame the work in the research papers which follow. Please consult https://link.springer.com/journal/volumesAndIssues/11207?tabName=topicalCollections for recent Topical Collections.

Topics to be included in the Topical Collection include:

·         Subsurface Flows, the Dynamo, and the Solar Cycle

·         Magnetic Flux in the SDO Era: From Emergence to Eruption

·         Vector Magnetic Field: Progress and Prospects

·         Energy and Mass Transfer Between the Corona and the Chromosphere

·         Short-term Solar Variability

·         Phun with Photons: Response of atmospheres to EUV variability

·         The SDO Corona and Beyond

·         SDO for Space Weather: Science and Applications

For further information, and submission of statements of intent, please contact John Leibacher (Solar Physics editor: john.leibacher.sola@gmail.com) or Dean Pesnell (guest editor), Ryan Milligan (guest editor), and Shin Toriumi (guest editor) at solar.cycle.with.sdo@gmail.com.

Calibration Maneuvers Today

SDO will execute two calibration maneuvers on April 7, 2021. The EVE Field of View (FOV) maneuver will begin at 1315 UTC (8:15 am ET). The HMI/AIA Flatfield maneuver will begin at 1630 UTC (11:30 am ET). During a calibration manuever the SDO science data may be missing or blurred. HMI science data is only available when SDO is in Sun-pointing mode.
Here is an AIA 171 Å picture from today's maneuver. The straight edges on the left and top show that SDO is pointed slightly away from Sun center. The image is re-centered by the processing software.
