Hi, I just have a question about astro.com... I tried out a hypothetical test, to see if I was born 5 minutes earlier what my rising sign would have been. Well I went from being a 28 degrees Sag rising to a 27 degrees Sag rising. Within a five minute timeframe, shouldn't the degree difference be greater? I thought that the sign ascending on the horizon moved by about 4 degrees every two minutes? If so, shouldn't that make my hypothetical "5 minutes earlier" ascendant at 20 degrees Sag, not 27 degrees? I realise this makes not much difference for me as I would still be a Sag rising, but it would make all the difference to someone whose ascendant was in the earlier degrees.I could have this all wrong, so hopefully some of the experts here can enlighten me! (Maybe it's something to do with my location being very low in the Southern Hemisphere? I know this makes a difference to some things, which is why it's recommended we use Placidus down here because Equal houses can create distortions for us. However I keep getting the same result with this whether I use Placidus or Equal). IP: Logged |

24 hours divided by 12 signs divided by 30 degrees equals one change in degree every 4 minutes.Thats what I thought, the maths makes sense anyway. IP: Logged |

Books generally use the 4-minute rule just because it's nice and even. According to what I've read, the "actual" speed of each ascendent varies. In the Northern hemisphere, Libra rises the longest time for a total of 2 hours and 30 minutes, and Aries rises the shortest time for only 1 hour and 10 minutes. It's different in the Southern hemisphere. IP: Logged | |
