Re: Publication "Cultural heritage of astronomical observatories"
Unfortunately, this book is out of print. In June this year I ordered it from the publisher (at a price of about 20 Euro), but I got the answer that it is no longer available.

Pictures for Astronomy Day
Hi everyone, This Saturday is Astronomy Day, October 16 2010. My astronomy club is having a solar observing session at a local library. I am having another one of my educational sundial displays again. I want to add a couple pictures to my display. I am looking for an example of a large public bifilar sundial. I thought I saw a picture of one on this list somewhere? I have a picture of Thomas Hughes’s Sidereal Sundial from the 2002 NASS Conference in Tucson, AZ. Are there any new pictures of a sundial that tells sidereal time? Thanks in advance, Ken Clark Elizabethtown, PA --- https://lists.uni-koeln.de/mailman/listinfo/sundial
RE: rescue me (off topic)
These topics are well explored in emergency navigation books, such as Harold Gatty's classic "The Raft Book" and the excellent modern "Emergency Navigation" by David Burch. And there are many web site about Polynesian navigation. You might not be able to pinpoint your location but you can certainly find your way without access to clocks and other sophisticated instruments. ...Tom Kreyche -Original Message- From: sundial-boun...@uni-koeln.de [mailto:sundial-boun...@uni-koeln.de] On Behalf Of Frank Evans Sent: Friday, October 15, 2010 8:04 AM To: Sundial Subject: Re: rescue me (off topic) Greetings fellow dialists, Brent posits: "Suppose I was on an island in the middle of the ocean".

Re: A giant non-dial for Milton Keynes??
Hi Tony et al, The buried sundial is on the BBC website at http://www.bbc.co.uk/ahistoryoftheworld/objects/Aa1Ir_diS7iBuKens1XJWQ I described it in an article in the BSS Bulletin, 16(ii), p.57 (June 2004). The Manchester Road railway station dial has also been the subject of Bulletin articles, by John Wall and Roger Bowling. Full references to anyone interested...

Not really to do with Sundials, but some good shadows...
