Chart for visually determining PSSR MC movement relative to Interval time

[Guest guest]

I have posted in the FILES section a chart that can be used to

circumvent some of the math work required to work with PSSRs. This

chart aids you in visually determining the relationship between the

MC movement from a PSSR MC to a give event date (between successive

Solar Returns) or (working the other way around) find the number of

interval days for the PSSR MC to reach another specific angle.

 

Not all of us (perhaps most of us) have software that will do this

math for us. I'm lazy. This chart gives results that are accurate

within a day and a half or within 2 degrees for the MC. Given that

we are always looking at a moving picture of time and events, that

degree of accuracy is good for preliminary work and assessment.

 

This chart can be freely used by anyone for their own purposes or

for instructional purposes but may not be used commercially for your

own profit. Dave.
