Ground-based monitoring of the variability of visible Solar spectral lines for improved understanding of solar and stellar magnetism and dynamics
S. Criscuoli, L. Bertello, D. P. Choudhary +7
Long-term high-cadence measurements of stellar spectral variability are fundamental to better understand stellar atmospheric properties and stellar magnetism. These, in turn, are f…
Ground-based Solar Observations for Space Weather Forecasting
A. G. Tlatov, A. A. Pevtsov
The possibilities of organizing an observation service for solar activity in order to provide space weather forecasting are considered. The most promising at this stage is the crea…
Camera update for GONG refurbishment: Development and validation
Anna L. H. Hughes, Timothy J. Purdy, Thomas M. Wentzel +9
This report provides a brief summary of the properties of new cameras selected for NSF's Global Oscillations Network Group (GONG) facilities operated by the NSO Integrated Synoptic…
Variation of small scale magnetic fields over a century using Ca-K images as proxy
Jagdev Singh, Muthu Priyal, B. Ravindra +2
A combined uniform and long-time series of Ca-K images from the Kodaikanal Observatory (KO), Mount Wilson Observatory (MWO), and Mauna Loa Solar Observatory (MLSO) were used to ide…
Re-calibration of the Sunspot Number: Status Report
F. Clette, L. Lefèvre, T. Chatzistergos +18
We report progress on the ongoing recalibration of the Wolf sunspot number (SN) and Group sunspot number (GN) following the release of version 2.0 of SN in 2015. This report consti…
