National Solar Observatory predicts large sunspot Thanksgiving
2020/12/11
Scientists at the U.S National Science Foundation National Solar Observatory have predicted the emergence of a new sunspot group just in time for Thanksgiving.Using a technique called h...
2011 was a successful year for the GREGOR project. The telescope was finally completed in May with the installation of the 1.5-meter primary mirror. The installation of the first-light focal plane ins...
Observations of the December 13 and 14, 2006, Solar Particle Events in the 80 MeV/n - 3 GeV/n range from space with PAMELA detector
Observations Solar Particle Events detector
2011/10/13
We present the space spectrometer PAMELA observations of proton and helium fluxes during the December 13 and 14, 2006 solar particle events. This is the first direct measurement of the solar energetic...
A method for filling gaps in solar irradiance and in solar proxy data
method filling gaps solar irradiance solar proxy
2011/10/13
Data gaps are ubiquitous in spectral irradiance data, and yet, little effort has been put into finding robust methods for filling them. We introduce a data-adaptive and nonparametric method that allow...
Software for Interactively Visualizing Solar Vector Magnetograms of Udaipur Solar Observatory
Instrumentation polarimetry spectroscopy
2010/9/15
The Solar Vector Magnetograph (SVM) at Udaipur Solar Observatory saw its first light in April 2005. The retrieval of vector fields from the imaging spectro-polarimetric observational data requires a s...
