Table 66. 



P is the position angle of the North end of the body's axis measured eastward from the North Point of the disc. B, L 

 are the helio-(planeto-)graphical latitude and longitude of the centre of the disc. In the case of Mars, T is the time of 

 passage of Fastigium Aryn across the centre of the disc. In the case of Jupiter, L x refers to the equatorial zone; L 2 to 

 the temperate zones; T x , T 2 are the times of passage of the two zero meridians across the centre of the disc ; to find inter- 

 mediate passages apply multiples of 9 h 50i m , 9 h 55j m respectively. 



The letters m, e, stand for morning, evening. The day is taken as beginning at midnight. 



The asterisk indicates the day following that given in the date column. 



The Sun continues his Southward march, but with slacken- 

 ing speed. Sunrise during November changes from 6.53 to 7.44, 

 sunset from 4.35 to 3.53. Its semi-diameter increases from 

 16' 9" to 16' 15". Outbreaks of spots in high latitudes should 

 be watched for. 



Mercury is an evening star till 23rd. It reaches greatest 

 elongation (23£° E) on 2nd, but, being South of Sun, is not 

 well placed for observation by Northern observers. Illumina- 

 tion diminishes from § to Zero, then increases to iV Semi- 

 diameter increases from 3" to 5". 



Venus is a morning star, rising 2 hours before the Sun. 



Semi-diameter diminishes from 5i" to 5i". At beginning of 

 month A of disc is illuminated; at end of month 3$. Being 

 North of Sun it is favourably placed for Northern observers. 



The Moon.— First Quarter 5 d 6 h 34 m e; Full 13 d 11" ll m e ; 

 Last Quarter 21 d 7 h 56 m m. New 28 d l h 41 m m. Apogee

 diameter 16' 22". Maximum Librations, l d 7° N, 2 d 7° W, 

 16 d 7° S„ 17" 5° E, 29 d 7° N, Dec l d 6° W. The letters 

 indicate the region of the Moon's limb brought into view by 

 libration. E. W. are with reference to our sky, not as 

 they would appear to an observer on the Moon (see Table 67).

From New to Full disappearances take place at the Dark Limb, from Full to New reappearances.
