Serving this website and Rob van Gent's astronomy history pages is the only remaining activity of Utrecht University in astronomy after pursuing this field during 1642 - 2011.  To study astronomy in The Netherlands you must go to Amsterdam, Groningen, Leiden, or Nijmegen.  To become a solar physicist you better go to Göttingen, Oslo, Stockholm, La Laguna.

Verantwoording:  ik jatte "webstek" niet van onnavolgbare Interim Dichter des Vaderlands Simon Vinkenoog (1928-2009) maar van onnavolgbare collega-sterrenkundige Vincent Icke.
