Detection of Flux Emergence, Splitting, Merging, and Cancellation of Network Fields. II Apparent Unipolar Flux Change and Cancellation
Y. Iida, H. Hagenaar, T. Yokoyama
In this second paper in the series, we investigate occurrence frequencies of apparent unipolar processes, cancellation, and emergence of patch structures in quiet regions. Apparent…
Detection of flux emergence, splitting, merging, and cancellation of network field. I Splitting and Merging
Y. Iida, H. Hagenaar, T. Yokoyama
Frequencies of magnetic patch processes on supergranule boundary, namely flux emergence, splitting, merging, and cancellation, are investigated through an automatic detection. We u…
Detection of flux emergence, splitting, merging, and cancellation in quiet Sun
Y. Iida, H. Hagenaar, T. Yokoyama
We investigate the frequency of magnetic activities, namely flux emergence, splitting, merging, and cancellation, through an automatic detection in order to understand the generati…
Fine Scale Magnetic Fields in and around a Decaying Active Region
K. Sankarasubramanian, H. Hagenaar
High spatial resolution spectro-polarimetric observation of a decaying spot was observed with the Diffraction Limited Spectro-Polarimeter. The spatial resolution achieved was close…
The Fine-Structure of the Net-Circular Polarization in a Sunspot Penumbra
A. Tritschler, D. A. N. Mueller, R. Schlichenmaier +1
We present novel evidence for a fine structure observed in the net-circular polarization (NCP) of a sunspot penumbra based on spectropolarimetric measurements utilizing the Zeeman…
Solar Magnetic Tracking. I. Software Comparison and Recommended Practices
C. E. DeForest, H. J. Hagenaar, D. A. Lamb +2
Feature tracking and recognition are increasingly common tools for data analysis, but are typically implemented on an ad-hoc basis by individual research groups, limiting the usefu…
