Moderate Nesting and Cross-Equatorial Asymmetry of Active Regions in Solar Cycle 24
Aimee Norton, Alex Mendez, Ruizhu Chen +2
Solar Cycle 24 data are used to determine how often the Sun emerges sunspots in `activity nests', i.e., regions where sunspots and active regions (ARs) repeatedly emerge. We use th…
Magnetic helicity and energy budgets of jet events from an emerging solar active region
A. Nindos, S. Patsourakos, K. Moraitis +4
Using photospheric vector magnetograms obtained by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory and a magnetic connectivity-based method, we compute…
Magnetic Flux Emergence and Decay Rates for Preceder and Follower Sunspots Observed with HMI
A. A. Norton, E. H. Jones, M. G. Linton +1
We quantify the emergence and decay rates of preceder (p) and follower (f) sunspots within ten active regions from 2010-2014 using Space-weather Helioseismic Magnetic Imager Active…
Tilt Angle and Footpoint Separation of Small and Large Bipolar Sunspot Regions Observed with HMI
Bruce H. McClintock, Aimee A. Norton
We investigate bipolar sunspot regions and how tilt angle and footpoint separation vary during emergence and decay. The Helioseismic and Magnetic Imager on board the Solar Dynamic…
Re-examining Sunspot Tilt Angle to Include Anti-Hale Statistics
Bruce H. McClintock, Aimee A. Norton, Jing Li
Sunspot groups and bipolar magnetic regions (BMRs) serve as an observational diagnostic of the solar cycle. We use Debrecen Photohelographic Data (DPD) from 1974-2014 that determin…
Hemispheric Coupling: Comparing Dynamo Simulations and Observations
Aimee A. Norton, Paul Charbonneau, Dario Passos
Numerical simulations that reproduce solar-like magnetic cycles can be used to generate long-term statistics. The variations in N-S hemispheric cycle synchronicity and amplitude pr…
The Sun's interior structure and dynamics, and the solar cycle
A. -M. Broomhall, P. Chatterjee, R. Howe +2
The Sun's internal structure and dynamics can be studied with helioseismology, which uses the Sun's natural acoustic oscillations to build up a profile of the solar interior. We di…
The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: Optimization of the Spectral Line Inversion Code
R. Centeno, J. Schou, K. Hayashi +5
The Very Fast Inversion of the Stokes Vector (VFISV) is a Milne-Eddington spectral line inversion code used to determine the magnetic and thermodynamic parameters of the solar phot…
Recovering Joys Law as a Function of Solar Cycle, Hemisphere, and Longitude
Bruce H. McClintock, Aimee A. Norton
Bipolar active regions in both hemispheres tend to be tilted with respect to the East West equator of the Sun in accordance with Joys law that describes the average tilt angle as a…
