Small Platforms, High Return: The Need to Enhance Investment in Small Satellites for Focused Science, Career Development, and Improved Equity
James Paul Mason, Robert G. Begbie, Maitland Bowen +33
In the next decade, there is an opportunity for very high return on investment of relatively small budgets by elevating the priority of smallsat funding in heliophysics. We've lear…
Two New Methods for Counting and Tracking the Evolution of Polar Faculae
Beryl Hovis-Afflerbach, W. Dean Pesnell
Polar faculae (PFe) are the footpoints of magnetic field lines near the Sun's poles that are seen as bright regions along the edges of granules. The time variation in the number of…
SunCET: A compact EUV instrument to fill a critical observational gap
James Paul Mason, Phillip C. Chamberlin, Daniel Seaton +16
The Sun Coronal Ejection Tracker (SunCET) is an extreme ultraviolet imager and spectrograph instrument concept for tracking coronal mass ejections through the region where they exp…
Characteristics of ephemeral coronal holes
Andrew R. Inglis, Rachel E. O'Connor, W. Dean Pesnell +2
Small-scale ephemeral coronal holes may be a recurring feature on the solar disk, but have received comparatively little attention. These events are characterized by compact struct…
Roadmap for Reliable Ensemble Forecasting of the Sun-Earth System
Gelu Nita, Rafal Angryk, Berkay Aydin +44
The authors of this report met on 28-30 March 2018 at the New Jersey Institute of Technology, Newark, New Jersey, for a 3-day workshop that brought together a group of data provide…
Deciphering Solar Magnetic Activity I: On The Relationship Between The Sunspot Cycle And The Evolution Of Small Magnetic Features
Scott W. McIntosh, Xin Wang, Robert J. Leamon +6
Sunspots are a canonical marker of the Sun's internal magnetic field which flips polarity every ~22-years. The principal variation of sunspots, an ~11-year variation in number, mod…
The EUV emission from sun-grazing comets
Paul Bryans, W Dean Pesnell
The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO) has observed two sun-grazing comets as they passed through the solar atmosphere. Both passages result…
Comparisons of Supergranule Characteristics During the Solar Minima of Cycles 22/23 and 23/24
Peter E. Williams, W. Dean Pesnell
Supergranulation is a component of solar convection that manifests itself on the photosphere as a cellular network of around 35 Mm across, with a turnover lifetime of 1-2 days. It…
Photospheric Manifestations of Supergranules During the Last Two Solar Minima
P. E. Williams, W. D. Pesnell
Solar supergranulation plays an important role in generating and structuring the solar magnetic field and as a mechanism responsible for the 11-year solar cycle. It is clearly dete…
Automated Detection of EUV Polar Coronal Holes During Solar Cycle 23
Michael S. Kirk, W. Dean Pesnell, C. Alex Young +1
A new method for automated detection of polar coronal holes is presented. This method, called perimeter tracing, uses a series of 171, 195, and 304 Å full disk images from the Extr…
