Temporal and Periodic Variation of the MCMESI for the Last Two Solar Cycles; Comparison with the Number of Different Class X-Ray Solar Flares

A. Kilcik, P. Chowdhury, V. Sarp +4

In this study we compared the temporal and periodic variations of the Maximum CME Speed Index (MCMESI) and the number of different class (C, M, and X) solar X-Ray flares for the la…

Spatial Distribution of Origin of Umbral Waves in a Sunspot Umbra

Vasyl Yurchyshyn, Ali Kilcik, Seray Sahin +2

Umbral flashes (UFs) are emissions in the core of chromospheric lines caused by upward propagating waves steepening into shocks. UFs are followed by an expanding blue shifted umbra…

How big is the Sun: Solar diameter changes over time

J. P. Rozelot, A. G. Kosovichev, A. Kilcik

The measurement of the Sun's diameter has been first tackled by the Greek astronomers from a geometric point of view. Their estimation of ~1800", although incorrect, was not truly…
