Long-Period Oscillations of Sunspots Observed by SOHO/MDI
V. I. Efremov, L. D. Parfinenko, A. A. Solovev +1
We processed magnetograms that were obtained with the Michaelson Doppler Imager onboard the Solar and Heliospheric Observatory (SOHO/MDI). The results confirm the basic properties…
Supergranulation Velocity Field from the MDI (SOHO) Data
L. D. Parfinenko, V. I. Efremov, A. A. Solovev
Long (up to 100 hours) time series of SOHO/MDI Doppler data are analyzed. The power spectrum of radial velocity time series in the quiet photosphere is observed to have, along with…
Identification of large-scale cellular structures on the Sun based on the SDO and PSPT data
V. I. Efremov, L. D. Parfinenko, A. A. Solovev
Three independent sets of data: i). series of filtergrams obtained in line CaII K (393.416 nm) with the ground-based telescope Precision Solar Photometric Telescope (PSPT) of Mauna…
