Maximum Coronal Mass Ejection Speed as an Indicator of Solar and Geomagnetic Activities
A. Kilcik, V. B. Yurchyshyn, V. Abramenko +4
We investigate the relationship between the monthly averaged maximal speeds of coronal mass ejections (CMEs), international sunspot number (ISSN), and the geomagnetic Dst and Ap in…
Time Distributions of Large and Small Sunspot Groups Over Four Solar Cycles
A. Kilcik, V. B. Yurchyshyn, V. Abramenko +4
Here we analyze solar activity by focusing on time variations of the number of sunspot groups (SGs) as a function of their modified Zurich class. We analyzed data for solar cycles…
Properties of Umbral Dots as Measured from the New Solar Telescope Data and MHD Simulations
A. Kilcik, V. B. Yurchyshyn, M. Rempel +5
We studied bright umbral dots (UDs) detected in a moderate size sunspot and compared their statistical properties to recent MHD models. The study is based on high resolution data r…
