Hi all, One of my teachers and I had a chat today about the relative position of the sun during sunrise *in summer*. Ok, so that is not the most interesting topic on Earth... I know :-) But it is relevant to that class, in order to study how the sun (...) (22 years ago, 20-Nov-02, to lugnet.loc.au)

(...) Mmmmmm summer.... Mmmmmm warmth :) (...) Well, I don't live much down-under than 'down-under'... But Southwise... I think this needs to be directed to a Tasmanian :) Or even a Victorian :) I'm sure Ross would help you in that case... otherwise (...) (22 years ago, 20-Nov-02, to lugnet.loc.pt)

(...) Ok, so this confirms our suppositions. Is this noticeable, though? I mean, if you live, say, at 25ºS, would you notice the slight "Southwise" angle during sunrise? (...) Remember, sunset works just as well! (I don't get to see sunrise as well, (...) (22 years ago, 20-Nov-02, to lugnet.loc.pt)

(...) Hi Pedro, I live in the Sydney region, approx 33degrees south. I really notice the differnece in angle of the sun from winter to summer. I am fortunate in having a north-facing verandah where i often enjoy breakfast and dinner, anyway (enough (...) (22 years ago, 21-Nov-02, to lugnet.loc.pt)

Hi Pedro, Not sure if you've got all the info you need now, but I'm in Tasmania (-42deg58'). I don't often see sunrise as I have a baby that doesn't go to sleep until around midnight and sunrise today was 0532 daylight savings time, I need much more (...) (22 years ago, 22-Nov-02, to lugnet.loc.pt)

Hi again, The weather has finally co-operated (more or less!) it was a bit hazy, so an approximate reading for the sunset was 230 degrees. This was observed at approx 2012 (daylight savings time). However, the official sunset time at my location for (...) (22 years ago, 25-Nov-02, to lugnet.loc.pt)
