stonyhurst explanation
[edit]The explanation of stonyhurst system doesn't give any indication of which direction latitude an longitude go. I suppose positive latitude numbers mean up, but it doesn't say which way is up. For longitude which way is left, and is it positive or negative? Does up change from morning to evening, or northern/southern hemisphere on earth? ~2026-26254-77 (talk) 23:51, 29 April 2026 (UTC)
