Solar Papers

 

 

Below is a list my solar papers and articles:

·      Meadows, P.J., ‘Re-Measurement of Solar Observing Optical Network Sunspot Areas’, Accepted for publication in the Monthly Notices of the Royal Astronomical Society. 2020.

 

·      Peter Meadows, ‘The Five Greatest Sunspot Groups’, Accepted for publication in the Journal of the British Astronomical Association. 2020. A longer version of this paper is also available.  This includes a comparison of Greenwich, Mt Wilson & Hisako Koyama sunspot areas and various appendices.  These are on the distribution of large sunspot groups within solar cycles, a cycle sunspot number as a better way to characterise the strength of a solar cycle, a description on how the Mt Wilson and Koyama drawings have been used to extract the position and size of the great groups and differential rotation models for proper motion estimation.

 

·      Peter Meadows, ‘Sunspot Groups without Active Region Numbers’, Accepted for publication in the Journal of the British Astronomical Association. 2019.

 

·      Peter Meadows, Lyn Smith and John Cook, ‘A comparison of BAA Solar Section White Light Measurements’, Accepted for publication in the Journal of the British Astronomical Association. 2019.
