Transition of 02/02-03/19 of white spot by Ralf Vandebergh; 白斑の02/02-03/19の推移

For documentation is here is a provisional overview of my best observations of the STrZ-storm in February and March.
With 'best' is meant when the seeing was not too poor.
The spot looks compact in the Febr 2 and Febr 14 image.
In the Febr 26 image it seems it became bigger already,and from that time,it only has grown.
