Description
The evolution of NOAA11024 from a protospot into a
fully-developed sunspot was followed in detail from
high-resolution observations. The affluence of continuously
emerging magnetic flux assembling the developing spot, the
action of twist and shear motions, the presence of a broad
magnetic canopy beyond the spot intensity boundaries, the
role of light bridges as natural path to gather the new
inflowing flux and the presence of abnormal
(counter-)Evershed plasma flows seem to be all some of the
necessary ingredients to ignite the formation of penumbrae
within time scales of 2 hours (and of about 5 hours to shape
a fully-fledge sunspot). These and other observational
properties will be put together in order to draw a
comprehensive picture of the formation of NOAA11024 in
particular and of sunspot formation in general.
