Chart as above generated by Astrolog; edited to include Part of Fortune (POF) and Asteroids (Chiron, Ceres, Juno, Pallas, Vesta).

Formula:

1. Ascendant + Moon - SAN*
   PREFERRED FORMULA. [Formula from Bonatti, as given in translation included on pages 81-133 of Robert Zoller's book Arabic Parts in Astrology: A Lost Key to Prediction. New York: Inner Traditions, 1980.
2. Asc + New or Full Moon Prior to Birth - Moon
   [Formula from Robert Hurzt Granite. The Fortunes of Astrology: A New Complete Treatment of the Arabic Parts. San Diego, CA: ACS Publications, 1980.]

NOTE: I would very much like to thank Sandy Curran for her help, discussion, insights, research, etcetera in clarifying which of these formulae is to be preferred in use.

  28 LI 53 = ASC
+ 08 AR 07 = Moon of Native
- 14 PI 26 = Full Moon Prior to Birth

Step 1: Convert all degrees to 360 framework.

AR = 0 / 360
TA = 30
GE = 60
CA = 90
LE = 120
VI = 150
LI = 180
SC = 210
SA = 240
CA = 270
AQ = 300
PI = 330

  208:53 = ASC
+ 008:07 = Moon of Native
- 344:26 = Full Moon Prior to Birth

Step 2: Do the math

208:53 + 008:07 = 216:60

NOTE: The second portion of the number will also need to be brought back within "60", since that is the base for that section of the number. Thus the "60" should really be "1:00", making the number 217:00. For those of you who think mathematically, we actually working with a compound numeral representing two separate bases. Part one of the number (before the ":") is in 360, and part two (after the ":") in 60. This concept is VERY difficult for many of my students, and just giving examples is the only way I've found to explain it. I allocate a "lot" of time to how to calculate lots!

217:00 - 344:26 = ???

Oops! 344 is larger than 217, which would give us a negative number to then place within the 360 degree circle. Personally, I find it simpler to add 360 to the 217, rather than doing the reverse with the negative number later.

577:00 - 344:26 = 232:34

Step 3: Translate back to sign and place in chart.

This goes just barely inside the 2nd house of the chart, conjunct the second house cusp.
