Observations of Sunspots by Fuxian Solar Observatory
摘要
Abstract
Oscillations and waves are a type of fundamental phenomena occurring in sunspots.It is important to measure the oscillation period for understanding the evolution of sunspots.A high temporal resolution observation images of the sunspot within the active region AR 11692 was carried out by NVST(The 1m New Vacuum Solar Telescope) at FSO(Fuxian Solar Observatory) in March 13,2013 at the Hα(6 562.80(A)) line.The high quality observations give us a good chance to measure the oscillation period.By using Fast Fourier Transformation(FFT),we derive the umbra oscillation period of the sunspot is 165 s,which means the umbra oscillation in the Hα(6 562.80(A)) line formation region is a typical 3 min oscillation,and existing a typical 5min oscillations at penumbra area,the oscillation period is 283 s.关键词
