Structural features of sun photosphere under high spatial resolution

Autor: Soloviev, A. A., Parfinenko, L. D., Efremov, V. I., Kirichek, E. A., Korolkova, O. A.

The main small-scale elements observed in the solar photosphere at high resolution are discussed: granules, faculaes, micropores. As a separate element of the fine structure, a continuous network of dark intergranular gaps is considered. The results

Long-Term Oscillations of Sunspots and a Special Class of Artifacts in SOHO(MDI) and SDO(HMI) Data

Autor: Efremov, V. I., Soloviev, A. A., Parfinenko, L. D., Riehokainen, A., Kirichek, E., Smirnova, V. V., Varun, Y. N., Bakunina, I., Zhivanovich, I.

A specific type of artifacts, that originate due to displacement of the image of a moving object along the digital (pixel) matrix of receiver are analyzed in detail. The criteria of appearance and the influence of these artifacts on the study of long

Long-Period Oscillations of Sunspots Observed by SOHO/MDI

Autor: Efremov, V. I., Parfinenko, L. D., Solovev, A. A., Kirichek, E. A.

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 of long-period oscillations of sunspots that have previously been esta
