Sun entered the last right ascension hour in early March (23h / 24h * 365¼ = 350.0). But the Gregorian leap day came first, at Ca13-2 (where 13 * 2 = 26). What star did Sun visit at that time?
I have here above counted the RA positions mechanincally forward, counting with February 29 as RA day 345. But that does not seem to be correct, because my model for right ascension days is based on the length of an ordinary Julian year (365¼ days). Should I continue to count this way to the March equinox then RA day 365 will be at March 1 + (365 - 346) = March 20 instead of at March 21. In a leap year there must be a gap somewhere as compared to the ordinary year, and this gap ought to be in the odd day February 29. Thus I should change my table above:
