June 2011: the board of Utrecht University decides to
with it kill Dutch solar
physics. To study physics and astronomy in The
Netherlands one now has to go to Amsterdam, Groningen, Leiden, or
Nijmegen. Om natuurkunde en sterrenkunde te studeren kun je niet
meer naar het zogenaamde Departement Natuur- en Sterrenkunde van de
zogenaamde Universiteit Utrecht maar moet je naar Amsterdam,
Groningen, Leiden, of Nijmegen.

Dutch Open Telescope.
It is mothballed since but you are welcome to revive it.
November 2010: "citeads" latex commands
that generate citations in a pdf file which
link to the corresponding ADS abstract page.
November 1999: reprint
of a popular-astronomy
article (Zenit) on what one did not see during the August 11
eclipse (in Dutch). What one did not see are the Fraunhofer lines!
The inner corona is the only sunshine-illuminated body in the entire
solar system that does not show them. Walter Grotrian
explained their absence in 1934 as due to enormous Doppler smearing
in Thomson scattering, but without daring to suggest that such large
electron velocities indicate very high temperature. He did that
only much later, after identifying the few coronal emission lines in
the visible as due to highly ionized iron. During a total solar
eclipse you should particularly appreciate that the corona basks you
in pearly sunshine without Fraunhofer lines (and polarized as well).
