Sheratan (B Arietas), fiducal star for the 1st Lunar Mansion (and for the first nakshatra Aswini) is now (longitudinally) posited at tropical Taurus 4degrees08; those of us (those very few of us!) who use both the tropical zodiac and also take fixed stars and constellations and nakshatras/Lunar Mansions into account as well, have no problem in combining, contrasting and then synthesizing the indications from each consideration, in coming to our delineative determinations...relative to the hypothetical example of Sun in tropical Taurus conjunct Sheratan, we would say: a basically Taurus underlying quality to the Sun, greatly modified by conjunction with Sheratan (and thus affected by Aries constellational qualities as well, which are channeled into the Sun via Sun's conjunction with B Arietis), modified further by the qualities of the Aswini nakshatra = the net Solar influence in this specific chart example.
