Detection and Characterisation of a Coronal Mass Ejection using Interplanetary Scintillation measurements from the Murchison Widefield Array
J. Morgan, P. I. McCauley, A. Waszewski +2
We have shown previously that the Murchison Widefield Array (MWA), can detect hundreds of Interplanetary Scintillation (IPS) sources simultaneously across a field of view $\sim30^\…
Radio Burst and Circular Polarization Studies of the Solar Corona at Low Frequencies
Patrick I. McCauley
Low-frequency (80-240 MHz) radio observations of the solar corona are presented using the Murchison Widefield Array (MWA), and several discoveries are reported. The corona is revie…
Comprehensive Characterization of Solar Eruptions With Remote and In-Situ Observations, and Modeling: The Major Solar Events on 4 November 2015
Iver H. Cairns, Kamen A. Kozarev, Nariaki V. Nitta +12
Solar energetic particles (SEPs) are an important product of solar activity. They are connected to solar active regions and flares, coronal mass ejections (CMEs), EUV waves, shocks…
Science with the Murchison Widefield Array: Phase I Results and Phase II Opportunities
A. P. Beardsley, M. Johnston-Hollitt, C. M. Trott +56
The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low frequency (80300 MHz) southern sky. Since beginning operations in mid 2013, the MWA…
The Low-Frequency Solar Corona in Circular Polarization
Patrick I. McCauley, Iver H. Cairns, Stephen M. White +4
We present spectropolarimetric imaging observations of the solar corona at low frequencies (80 - 240 MHz) using the Murchison Widefield Array (MWA). These images are the first of t…
A weak coronal heating event associated with periodic particle acceleration episodes
Atul Mohan, Patrick I. McCauley, Alpha Mastrano +1
Weak heating events are frequent and ubiquitous in solar corona. They derive their energy from the local magnetic field and form a major source of local heating, signatures of whic…
Nonlinear force-free modeling of flare-related magnetic field changes at the photosphere and chromosphere
Lucia Kleint, Michael S. Wheatland, Alpha Mastrano +1
Rapid and stepwise changes of the magnetic field are often observed during flares but cannot be explained by models yet. Using a 45 min sequence of SDO/HMI 135 s fast-cadence vecto…
Densities Probed by Coronal Type III Radio Burst Imaging
Patrick I. McCauley, Iver H. Cairns, John Morgan
We present coronal density profiles derived from low-frequency (80-240 MHz) imaging of three type III solar radio bursts observed at the limb by the Murchison Widefield Array (MWA)…
Type III Solar Radio Burst Source Region Splitting Due to a Quasi-Separatrix Layer
Patrick I. McCauley, Iver H. Cairns, John Morgan +4
We present low-frequency (80-240 MHz) radio imaging of type III solar radio bursts observed by the Murchison Widefield Array (MWA) on 2015/09/21. The source region for each burst s…
Direct Observations of Magnetic Reconnection Outflow and CME Triggering in a Small Erupting Solar Prominence
Katharine K. Reeves, Patrick I. McCauley, Hui Tian
We examine a small prominence eruption that occurred on 2014 May 1 at 01:35 UT and was observed by the Interface Region Imaging Spectrometer (IRIS) and the Atmospheric Imaging Asse…
Magnetic Structure and Dynamics of the Erupting Solar Polar Crown Prominence on 2012 March 12
Yingna Su, Adriaan van Ballegooijen, Patrick I. McCauley +3
We present an investigation of the polar crown prominence that erupted on 2012 March 12. This prominence is observed at the southeast limb by SDO/AIA (end-on view) and displays a q…
Prominence and Filament Eruptions Observed by the Solar Dynamics Observatory: Statistical Properties, Kinematics, and Online Catalog
Patrick I. McCauley, Yingna Su, Nicole Schanche +4
We present a statistical study of prominence and filament eruptions observed by the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO). Several properti…
The Solar Corona as probed by Comet Lovejoy (C/2011 W3)
J. C. Raymond, P. I. McCauley, S. R. Cranmer +1
EUV images of Comet Lovejoy (C/2011 W3) from the AIA show striations related to the magnetic field structure in both open and closed magnetic regions. The brightness contrast impli…
EUV and X-Ray Observations of Comet Lovejoy (C/2011 W3) in the Lower Corona
Patrick I. McCauley, Steven H. Saar, John C. Raymond +2
We present an analysis of EUV and soft X-ray emission detected toward Comet Lovejoy (C/2011 W3) during its post-perihelion traverse of the solar corona on December 16, 2011. Observ…
Dynamics of the Transition corona
Sophie Masson, Patrick McCauley, Leon Golub +2
Magnetic reconnection between open and closed magnetic field in the corona is believed to play a crucial role in the corona/heliosphere coupling. At large scale, the exchange of op…
