212. Deconvolving SDO/HMI Intensity and Vector Magnetic Field Data to Achieve Hinode/SOT-SP Quality

Contributed by David Korda. Posted on May 19, 2025

A deep convolutional neural network is trained using Hinode data that has been degraded to match the resolution and sensitivity of HMI observations. Once trained, the network can enhance HMI intensity and vector magnetic field data to the resolution and quality of Hinode.

211. Electric Current Neutralization and Critical Height of Flux Rope in Eruptive and Non-Eruptive Active Regions

Contributed by Johan Muhamad. Posted on May 12, 2025

Eruptive and non-eruptive solar flares were investigated based on an analysis of electric current neutralization and torus instability. Combined analysis of these factors offers a more reliable prediction of eruptive events than relying on either one alone.
