Tropical Storm Leslie is brewing in the mid-Atlantic. By Monday, it may begin to reach the west coast of Spain, much like where the beautiful curving cyclone visible in today's image is swirling. For now, central Europe is dotted with a few clouds but is otherwise relatively clear. This image from an automatic ground station in my flat was captured by a turnstile antenna leaning on the windowsill, its metal dipoles shining in the noon sunlight.
