Alexi:
I applied a little "Flat-Lander" geometry to your question, and came up with
the two following locations:
Latitude 35° 38' 33"N Longitude 13° 56' 0"E, and
Latitude 36° 9' 35"N Longitude 14° 48' 47"E.
These each gave a distance of 50km to both of the origins you listed, within
the + or - 1km accuracy afforded by the website calculation at
http://www.indo.com/cgi-bin/dist. I don't have any more accurate means of
checking this.
Hope this helps.

>Dear sundial enthusiasts
Today I wish to ask something non-sundial-related...
>I saw the very interesting website http://www.indo.com/cgi-bin/dist which
>calculates the distance between two places, given their latitudes and
>longitudes.
>
>However I wonder whether you can help me as regards another thing.

>I live in MALTA, Europe, and am trying to do meteor triangulation, and to
>do this I need the latitude and longitude of two places, equidistant from
>two other places by 50km.
>The two places I got have lats and long's as follows:
>Ras il-Qammieh - Latitude 35°58'27"N Longitude 14°18'30"E and
>Mnajdra - Latitude 35°49'41"N Longitude 14°26'17"E.
>
>Now I need to know the exact latitude and longitude of the two places 50km
>away from both of these localities. These lie on the two intersection
>points of two great circles with Ras il-Qammieh and Mnajdra as centres,
>and with radius 50km.

>I look forward to hearing from you.
