Sam Wormley wrote: RA 18h 0m 0s Epoch of Date Ecliptic Long 270° 0m 0s I think Nikolaj wants to know the longitude on Earth that is facing the Sun at the moment of the solstice. Offhand, the solstice happens at 23:32UT. So at what longitude is it local noon at that time? 12 hours from 23:32 gives us 11:32 hours past Greenwich, so at 15 degrees per hour, that's about 173 longitude - eastern end pf the Siberian peninsula, mid/west section of the Aleutioan chain, Samoa, Tonga... How exact do you want it? There's equation of time to consider, if you need real accuracy. ============= - Dale Gombert (SkySea at aol.com) 122.38W, 47.58N, W. Seattle, WA http://flavorj.com/~skysea

Winter solstice
I realise that I in essence asked the same question twice, but the
answer I was looking for was the answer given by Dale Gambert. But thank you all for your help and assistance.
