(Only a touch.) The angles are only 1-2' off, which admittedly is far better than we used to get using an ephemeris. Tropically, my SF Moon was 05" later than the first answer I was given (and 6" later than the one quoted from JPL in the second quote).Īstro gives 29★9'54" Sag, 7" earlier than my SF and agreeing, within about 1", with SF9 and JPL.Ĭonsequence: The lunar ingresses I've been relying on for my mundane work are minutely off. As we know, the delta-T value is slightly different between both sources, however, the UTC time scale is used in both:īTW, where my SF gives Sidereal 0☀0'01" Cap (SF calculated the ingress time), Danica said hers gives 0☀0'00". Other time tags would have to individually be compared to determine which version is closer to the gold standard with the Moon or other objects.įor comparison, the real-time SE calculation for this time tag is: 25° Cap 02'12.5023", 0.0468" difference with JPL Horizons. It seems that your SF version is less accurate for this time tag than the version Pam is using, if both results were typed correctly. So, to prevent confusion on this, I've converted the time given to UTC with the understanding that the local time in question is exactly 4 hours earlier (EDT) and precisely 75°W the day before. On the contrary, location does matter, since the Moon cannot be in the same position for observers at two different longitudes with both clocks arbitrarily synchronized. Like Pam said, we don't have an ayanamsha, hence the tropical position.

This according to JPL Horizons, the gold standard. the precise ecliptic longitude for comparison of the body-center of the Moon on, 0:21:39 UTC, is 25° Cap 02'12.4555". The link may be useful to you, as the output confirms that the SF9 answer is correct to within a fraction of a minute but mine isn't, and the poster is misinformed on time zones (as you'll see). I've asked for confirmation that the 3 wasn't a misread of an 8 p, but that became moot with another answer that I give her in full. Thank you.įrom someone with the newest version, I was given a Tropical longitude of 25☀2'13" Capricorn vs.

multiple other platforms using the same calculation base and, before diving in deeper, I want to rule out it being a version-specific issue.

Over the weekend, we found multiple examples of discrepancies (usually several seconds and, in one case, more than 1') in Solar Fire Moon positions vs. (Location doesn't matter, but use Washington, DC if you like.) If you can give this to me as a Sidereal longitude, it will save a possible rounding error when I convert from Tropical, but I'll take either. Speaking of rounding BTW, I don't think we should ever end with minutes or seconds at 60 - it should tip over ("zero and carry 1") the exception being that (as you've scrupulously done) we shouldn't tip into a new sign unless it has gotten all the way to 30☀0'00.00".Ĭould someone with SF 9 please confirm a calculation? (I have ver. So the disparity is not uniformly several seconds.Īlso, whereas the example I posted above showed most 1" discrepancies had SF 1" LESS than Astro, in my own chart most planets are 1" GREATER in SF therefore, this isn't something like a different rounding paradigm (which would consistently bias in the same direction). The first thing I notice is that these are much closer than other comparative examples - in fact, probably well under a second, since the rounding in Astro suggests that the value is between 59.5" and < 60.0" (not greater than the latter), while the former is between 58.5" and < 59.5".
