Warning 2012: Utrecht University killed all its astronomy including all DOT support, effectively terminating Dutch solar physics.  The last full observing season was the summer of 2010; since then the DOT is mothballed.  Revival is desirable, e.g. for Halpha mosaicing supporting space observations.

Warning 2020: web browser access to ftp directories is being deprecated by most or all browsers. The DOT database then remains accessible per lftp (instructions under DOT data) but not with the links given here or in the index and search engine until it is moved.
