Hello All,

In the QST of march 2015 on pages 94 & 95 there are a couple of diagrams
showing in Fig. 1 the activity from Jan-00 (2000) to Jan-19 (2019) on
the horizontal scale and on Fig. 2 400 Years of Sunspot Observations
with the Maunder and Dalton Minima shown on the diagram that extends
from year 1600 until 2015.

To learn about the effects of those two minima on the climate and humans
Google is your friend.

Have a nice day,

73 de Holger
