Analysis of Short-term Solar Activity Variability and Estimating the Timings of the Next Enhanced Bursts
Juie Shetye, Mausumi Dikpati
We present a hybrid forecasting strategy that combines numerical modeling, statistical forecasting, and machine learning methods to predict enhanced bursts of solar activity. These…
Compact Ca II K Brightenings Precede Solar Flares: A Dunn Solar Telescope Pilot Study
Aman Priyadarshi M. Kumar, Juie Shetye, Sean G. Sellers +1
We present a uniform analysis of compact Ca II K (3934 Ã ) brightenings that occur near flare kernels and assess their value as short-lead indicators of solar flare onset. Using hi…
