[Michael Rietveld]

Sadly, I have to report the death of John Titheridge on 27 December, 2010.
He was 78 and died with his family in Auckland, New Zealand, after a 
being diagnosed as having cancer earlier in the year.

John will be known to many of you through his early work on TEC, and
of course POLAN, the true-height ionogram inversion program used so widely.
He was finalising some notes on the latest version of POLAN, although most
of his time over recent years was spent with All Africa Mission work.

An obituary will appear in due course.
