The following are the particulars of stars occulted

!> 



The Planets.— Mercury is an evening star, and during 

 the early part of the month is fairly well placed for 

 observation. On the 1st he sets due N.W. shortly after 

 10 F.M , or two hours after the sun. On the 10th he sets 

 at 9.25 P.M.. or a little more than an hour after sunset. 

 He is at the stationary point on the 11th, in aphelion on 

 the 18th, and in inferior conjunction v^-ith the sun on 

 the 23rJ. 



Venus is a morning star, but is not very well suited for 

 observation as her brightness is diminishing. About the 

 middle of the month she rises in the E.N.E. shortly 

 before 2 a.m. 



Mars is also a morning star, but does not lend itself to 

 easy observation as he only rises in the early dawn about 

 an hour in advance of the sun. 



Jupiter is still iu Capricornus, and is becoming more 

 accessible for observing purposes. About the middle of 

 the month he rises shortly after 11 PM.,and comes to the 

 meridian about 4 a.m. The apparent diameter of the 

 planet is increasing, being 39"'6 on the 1st, and 43"0 on 

 the 30th. He is stationary on the 6th, after which he 

 describes a retrograde path, thus accelerating his diurnal 

 return to the meridian. 



Uranus is visible throughout the night, rising about 

 8.45 P.M. on the 1st, and about 6.40 on the 30th. He is 



in opposition on the 11th. The planet is situated a little 

 north of Ophiuchi, as is shown by the chart below, which 

 should enable it to be found readily. It shines with the 

 brightness of a 6th magnitiide star, and can be made out 

 on clear moonless nights with the naked eye, but, aided 

 bv a pair of opera-glasses, it is easily discernible. 



Saturn is becoming more favourably situated for 

 observation. During the month the planet describes a 

 short westerly path in Sagittarius, near the border of 

 Capricornus. On the 1st he rises at 11.10 p.m. and 

 transits at 3.23 a.m., whilst on the 30th he rises at 9.10 

 p.m. and souths at 1.22 a.m. The apparent diameter of 

 the planet is 16"-8, whilst the major and minor axes are 

 42"0 and 15"-5 respectively. 



Neptune is not observable, being in conjunction with 

 the sun on the 23rd.
