310 PAÑCASIDDHĀNTIKĀ XVII.13 Heliacal rising of the planets 12. The heliacal rising and setting of the Moon, Mars, Mercury, Jupiter, Venus and Saturn are when their elongation (from the true Sun) are 12°, 17°, 13°, 11°, 9°, and 15°. Note 1. I generally adopt TS's readings. But Śaśi is extra, and evidently a mistake which has crept into the reading. To make up for this they have removed rudra which is necessary, and this emen- dation has spoiled the correct agreement with other siddhāntas. Note 2. These are time-degrees, i.e. time expressed in degrees (kālabhāga) and are arbitrary in essence, and depend on the keennees of the observer's eyesight, as also the atmospheric conditions. The later Sūrya-Siddhānta gives 10° and 8° for Venus at superior and inferior conjunctions, and 14° and 12° for Mercury, respectively, while the Sūrya-Siddhānta here and some others give the mean of each. (The Mahābhāskarīya gives even 4° or 4 1/2° for Venus at inferior conj. and 8° at superior conj.)

Add one eighth of itself to the R (120') sine of (mean planet − apogee), in the case of Saturn, Jupiter and Venus. For, the two others, (i.e., Mercury and Mars), subtract one fourth of itself. (This is one part of latitude). There is another part of latitude using the Anomaly of conjunction. 14. From the R sine anomaly of conjunction of Jupiter, Mars and Venus sub- tract one fourth of itself. From that of the rest, (viz., Mercury and Saturn) add an eighth. Add both algebraically and note the direction, north or south. Multiply this by R (i.e. 120') and divide by the hypotenuse got in the last step. The latitude is got, its direction being that of the noted direction. 12a. A. स्फुट दिनकरांतरांतरांशाः; c. B. सौम्यपन्योः; B. स्फुरदिनकरांतरांतराशाः D. सौम्यारयोः A. पदोनां; B 1.2. पदनां b.
