Quantifying the Consistency and Characterizing the Confidence of Coronal Holes Detected by Active Contours without Edges (ACWE)
Jeremy A. Grajeda, Laura E. Boucheron, Michael S. Kirk +2
Coronal Holes (CHs) are regions of open magnetic field lines, resulting in high speed solar wind. Accurate detection of CHs is vital for space weather prediction. This paper presen…
An Analysis of Spikes in Atmospheric Imaging Assembly (AIA) Data
Peter R. Young, Nicholeen M. Viall, Michael S. Kirk +2
The Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) returns high-resolution images of the solar atmosphere in seven extreme ultraviolet (EUV) wavele…
The Observational Uncertainty of Coronal Hole Boundaries in Automated Detection Schemes
Martin A. Reiss, Karin Muglach, Christian Möstl +16
Coronal holes are the observational manifestation of the solar magnetic field open to the heliosphere and are of pivotal importance for our understanding of the origin and accelera…
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…
CME Acceleration as a Probe of the Coronal Magnetic Field
James Paul Mason, Phillip C. Chamberlin, Thomas N. Woods +5
By 2050, we expect that CME models will accurately describe, and ideally predict, observed solar eruptions and the propagation of the CMEs through the corona. We describe some of t…
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…
Relationships Between Sequential Chromospheric Brightening and the Corona
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +1
The chromosphere is a complex region that acts as an intermediary between the magnetic flux emergence in the photosphere and the magnetic features seen in the corona. Large eruptio…
The Origin of Sequential Chromospheric Brightenings
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +1
Sequential chromospheric brightenings (SCBs) are often observed in the immediate vicinity of erupting flares and are associated with coronal mass ejections. Since their initial dis…
Qualities of Sequential Chromospheric Brightenings Observed in Optical and UV Images
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +1
Chromospheric flare ribbons observed in H-alpha appear well-organized when first examined: ribbons impulsively brighten, morphologically evolve, and exponentially decay back to pre…
Sequential Chomospheric Brightening: An Automated Approach to Extracting Physics from Ephemeral Brightening
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +2
We make a comparison between small scale chromospheric brightenings and energy release processes through examining the temporal evolution of sequential chromospheric brightenings (…
Properties of Sequential Chromospheric Brightenings and Associated Flare Ribbons
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +2
We report on the physical properties of solar sequential chromospheric brightenings (SCBs) observed in conjunction with moderate-sized chromospheric flares with associated CMEs. To…
An Automated Algorithm to Distinguish and Characterize Solar Flares and Associated Sequential Chromospheric Brightenings
M. S. Kirk, K. S. Balasubramaniam, J. Jackiewicz +2
We present a new automated algorithm to identify, track, and characterize small-scale brightening associated with solar eruptive phenomena observed in Hα. The temporal spatially-lo…
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…
