TESS 2018 – Preparing for a Solar Polar Mission Townhall
Jeffrey Newmark
02 May 2018
Our current understanding of the Sun, its atmosphere, and the connection to the heliosphere is severely limited by the lack of good observations of the polar regions. An extended view of the high latitude regions of the Sun is the only method to obtain crucial observations not possible from the ecliptic viewpoint or from any other existing or planned mission. This workshop seeks to develop a community discussion on the science and mission implementation of a solar polar mission. It is crucial to start these discussions now, ahead of the preparations for the next Solar and Space Physics Decadal Survey. The meeting agenda will include presentations and an open call for science-driven community ideas.

Please join us during TESS on Monday, 21 May 2018, 19:45 - 21:00, Lansdowne Resort and Spa - Faulkner Room

Polar Perspectives 2018 (Boulder, CO, September 25 – 27, 2018) – A Workshop to Discuss Solar Polar Mission Readiness
Scott McIntosh
10 May 2018
Announcing The Polar Perspectives 2018 Workshop
September 25 - 27, 2018
NCAR/HAO: Boulder CO.


Workshop Charge: To explore the scientific breakthroughs made possible by repeated or sustained observations of the Sun’s polar regions, and to consider the technologies and orbital dynamics required to achieve measurements at the desired vantages.

Workshop Objective: Develop a science portfolio for a solar polar mission, present and discuss options on a baseline, and extended, suite of instrumentation, and develop a number of conceptual orbits available with existing launch capacity.

Workshop Motivation: For the first time in human history, our technology allows us to observe all longitudes of the solar atmosphere. The combined imaging data from SOHO, STEREO, and SDO have demonstrated some of the rotationally driven processes on our Star. They present a tantalizing glimpse of the Sun’s polar evolution when the data are pieced together, despite limitations arising the fact that all of these spacecraft are observing the poles from vantages close to the ecliptic plane. For decades, observations of high solar latitudes have been used as critical precursor input for predictions of decadal-scale solar activity. Many solar high-latitude phenomena—including polar coronal holes, polar crown filaments, and the Sun’s torsional oscillations—indicate a limiting latitude around 55 degrees (in each hemisphere) that apparently divides high- vs. low-latitude dynamical evolution. A polar view would directly reveal the Sun’s global-scale dynamics, investigate the sources of the fast solar wind, and witness the full lifetime of structures in the solar atmosphere from birth to death, including a Sun-to-Earth view of coronal mass ejections.

In this workshop we will take inventory of the science that might be accomplished by a solar polar mission. We will discuss mission architecture, maturity of required compact instrumentation, and technological limitations placed on any concept mission by currently available launch capacity and/or spacecraft propulsion systems.

An important precedent was set by the Ulysses mission, which obtained groundbreaking polar in-situ observations. Beyond this, numerous feasibility investigations of solar polar missions have already been undertaken. A key element of the workshop will be to capture the “lessons learned” from these past activities and to use them to effectively move forward in designing future solar polar missions.

HAO Workshop “Model Coupling and Data Driven Simulations of Solar Eruptions” *ndash; Mesa Lab of NCAR, Boulder, August 13–16, 2018: Meeting Registration Deadline June 1 2018
Yuhong Fan
14 May 2018
Registration at

HAO is hosting a workshop focusing on model coupling and data driven numerical simulations with the goal to improve the realism of modeling active region flux emergence and work towards simulating realistic solar eruptive events. Significant progress has been made in recent years in both of these areas. Near surface layer radiation MHD simulations of active region formation driven by lower boundary condition of emerging flux from a solar convective dynamo simulation are able to model sunspot and active region formation with realistic properties of the observed solar active regions. Methods of using observed time sequences of vector magnetograms to drive simulations of realistic solar eruptive events in the corona are being explored and developed.  This workshop will bring together modelers and observers working in these areas to review recent results, discuss methodologies and future directions.  The following are some of the questions to be addressed:

  1. What are the challenges of modeling realistic active region formation? How can model coupling be used to bridge the wide range of temporal and spatial scales (from global scale dynamo generation of active region flux to near surface layer fine scale evolution of sunspot formation) and the different physical regimes the problem encompasses?
  2. How coupled models and simulations can help us interpret surface observations of active region evolution in terms of the subsurface structure of emerging flux, and deriving the boundary driving condition for coronal models of solar eruption?
  3. Are photospheric observations of vector magnetic field evolution adequate to drive MHD models to be able to realistically model the magnetic field evolution of eruptive events? What additional observational data can be used?
  4. Many current CME simulations use ad-hoc boundary-driving to numerically construct a pre-eruptive coronal configuration and trigger its eruption. What are the adequate boundary conditions for such simulations, especially for the imposed electric fields? How can information derived from vector magnetic data or flux-emergence simulations be used to further increase their realism?

All interested in this area of research are welcome to participate in this workshop and present their work. The format of the workshop will be informal oral presentations and open discussion sessions. We hope to have useful and effective discussions on the above topics during the workshop. Some travel support is available for graduate student participants. Here is the workshop webpage where registration, hotel reservation, and application for travel support are open:

IAU XXX General Assembly (Vienna) – Focus Meeting 9: Solar Irradiance: Physics-Based Advances (22–23 August 2018): Abstract Deadline for Posters 31 May
Greg Kopp
14 May 2018
Sessions: We invite you to this Focus Meeting at the 2018 IAU General Assembly in Vienna to discuss recent physics-based advances in understanding the causes of brightness variability in the Sun and stars. The following two days of oral sessions are planned:

Scientific Rationale: Understanding and modeling of solar-irradiance variability is important for solar physics and for solar-terrestrial and solar-stellar studies. Some recent irradiance measurements question aspects of current empirical and semi-empirical models of solar-irradiance variability. New and more realistic physics-based irradiance models can now incorporate recent advances in modeling and observing the solar atmosphere. This next generation of irradiance models includes new advances in MHD, surface flux transport, and radiative transfer simulations as well as new state-of-the-art solar data. By relying on physics-based understandings, these new models will also allow more direct and physical extrapolations to other stars, opening a new regime for solar-stellar connection studies, as well as improved long-term estimates of historical solar variability.

Cool Stars 20 (Boston/Cambridge, USA, July 29–Aug 3 2018) – Splinter Session “Stellar Brightness Variations: Building on the Solar Knowledge”
Alexander Shapiro
14 May 2018
Abstract Submission: Please email your contribution to  We accept oral and poster contributions, please specify your preference.  Deadline for abstract submission is 1st of June 2018.


Scientific Rationale: The unprecedented precision of stellar brightness measurements achieved by the planet-hunting space telescopes initiated a new era in stellar photometric variability investigations. Understanding stellar brightness variations is of great interest to the solar, stellar, and exoplanetary communities, for the following reasons: Stellar brightness variations can provide constraints on the historical solar variability and solar role in climate change, as well as they allow to determine stellar magnetic cycles’ properties. Moreover, stellar brightness variations are a limiting factor for detection and characterisation of the exoplanets via transit photometry. Recently, a plethora of observational data have pushed ahead theoretical studies aiming at developing methods for extracting information about stars and their planets from the available records of brightness variations. These studies can greatly profit from knowledge acquired by studying the Sun. Thus the way forward is to focus on the solar-stellar comparison and examining how the solar paradigm can help us to explain variability of other stars and develop criteria for distinguishing between typical photometric signatures of intrinsic stellar variations and exoplanet transits.

SHINE 2018 – Session 22: Advancing Solar Activity Forecasts Through Observations, Data Assimilation and Machine Learning
Lisa Upton
14 May 2018
Early Bird Registration Deadline: May 18th, 2018 at midnight CT

Organizers: Irina Kitiashvili (NASA Ames & BAERI), Lisa Upton (HAO, NCAR)
Scene Setting Speakers: Thomas Berger (University of Colorado) and Petrus Martens (Georgia State University)
Session Date: Friday, August 3

Session Description:

Understanding of solar variability on different scales is a key to building reliable forecasts for short-term events (such as emergence of active regions, flares and CMEs), as well as for long-term variations on the scale of solar cycles. New observational data from space missions and ground-based observatories provide us with detailed information about the solar dynamics and magnetism from the interior to the heliosphere. However, because of limited coverage and uncertainties of both, observational data and models, it is challenging to combine the data with models and make reliable forecasts of solar activity.

New data enhancement capabilities, advanced numerical simulations, mathematical data assimilation and machine learning techniques have opened new perspectives for better understanding the basic mechanisms of solar activity, extracting additional information about processes hidden from direct observations, and developing physics-based models for activity forecast. In particular, machine leaning methods allow us to efficiently analyze large amount of data, classify multiscale physical and morphological properties, and identify most important characteristics of the onset and strength of solar eruptions. The data assimilation methods (such as Ensemble Kalman Filter, 4DVar etc.) allow us to take into account uncertainties in both observational data and models, and estimate the current and future states of underlying physical processes (such as the solar dynamo and magnetic flux rope eruption). Thus, the synergy of observational data with data assimilation and machine learning techniques can potentially lead to substantial improvement of short and long term operational forecasts of the solar activity.

The proposed session will bring expertise of observers, theoreticians and modelers and provide a unique platform to discuss the current status, needs and challenges for understanding and forecasting of solar activity on different temporal and spatial scales.

During the session the following questions will be discussed:

  1. What are the most critical observational data for characterization of multiscale properties of solar activity?
  2. What are the observational and theoretical challenges for understanding and predicting the solar activity?
  3. How can the data assimilation and machine learning approaches improve forecasting of solar activity on short and long time-scales?
Please take note of the following Meeting Dates and Deadlines:

We hope to see you there!

To make an email address invisible within the body of a SolarNews posting, and inaccessible to robots that collect them for spam, simply format it as @@text to appear@@email-address@@, for example "contact @@Jane" will appear as "contact Jane Doe".

To make a URL a "clickable" link in your posting, make sure that there is http:// (or https:// as appropriate) before it. Thus "" appears as simple text while "" will appear as "" and will allow the reader to access the URL by clicking on the link in the HTML version of SolarNews.   Of course, you can always just format the URL in an HTML submission; for example <A HREF=""></a>, which can be useful for an ftp or other server than http[s].

You can check your submission at, which is updated hourly, and let us know if something needs to be changed, for example remove a duplicate submission.

Please try to keep meeting and workshop announcements to no more than one page (fewer than 60 lines of typed text with 72 characters per line), with a Web address for further information.
