A New Comprehensive Data Set of Solar Filaments of 100 yr Interval. I
GangHua Lin, GaoFei Zhu, Xiao Yang +12
Filaments are very common physical phenomena on the Sun and are often taken as important proxies of solar magnetic activities. The study of filaments has become a hot topic in the…
Standard Magnetic Field Production at Huairou Solar Observing Station
Suo Liu, Ganghua Lin, Xiao Yang +3
The regular solar observations are operated at Huairou Solar Observing Station (HSOS) since 1987, which make the construction of long-term magnetic field datasets available to unde…
Transits of Venus and Solar diameter measures from ground: method and results from Athens (2004) and Huairou (2012)
Costantino Sigismondi, Anthony Ayiomamitis, Xiaofan Wang +3
The variation of the solar diameter in time and in position angle has implications in astrophysics and in general relativity, as the long series of studies attest. The Transits of…
Venus transit, aureole and solar diameter
Wenbin Xie, Costantino Sigismondi, Xiaofan Wang +1
The possibility to measure the solar diameter using the transits of Mercury has been exploited to investigate the past three centuries of its evolution and to calibrate these measu…
Geometrical information on the solar shape: high precision results with SDO/HMI
Xiaofan Wang, Costantino Sigismondi
The uncertainty of measurement of solar diameter is depending on the observational time scale. Full-disc images of SDO/HMI and the images from ground observations in Huairou Solar…
The power spectrum of the seeing during solar observations
Costantino Sigismondi, Andrea Raponi, Xiaofan Wang +3
Measurements of the power spectrum of the atmospheric seeing in the line of sight of the Sun, in the range 0.001-1 Hz, have been performed in Santa Maria degli Angeli Lucernaria Do…
