Weird house shifts in composite?
I was doing the composite between someone and myself and originally had his time of birth one minute off and so I realized my typo and went to change it. But when I adjusted it to only a minute later, the entire chart shifted to where our stellium moved from the 10th house to the 4th house.
when I incorrectly had his time of birth as 1:26pm, our stellium was in the 10th house and when I corrected it to 1:27pm, the entire thing shifted to the 4th house. Being a novice, I don’t know if this is normal or if there is phenomena which explains such a jump. This does not happen when I run his natal chart. Can anyone provide insight?
If it's an exact 12 hour jump, I would look at am/pm as the source.
A composite is made up of midpoints. Default method takes the closest midpoint but there are various ways of calculating the asc or the mc, depending o the program.
Example, A and B are 60 degrees apart. The close midpoint would be in the middle, 30 degrees from each point A and B. But there would be a second mid(dle) point, 180 degree opposite the first.
The other (far) midpoint would be 150 degrees from point a and b.
I suspect this is what happened here.
