Th« liist contact with the shadow occurs at (50° from the 

 N. jK)int of the moon's limb towards the west. 



The majjnitude of the eclipse, that is, the distance at 

 mid-totality of the most immersed limb of the moon to the 

 boundary of the shadow nearest the opposite limb divided 

 b_v the moon's diameter is r337. 



Of exceptional interest this month are the occultations 

 of the bright stars T Tauri and Spica. the particulars of 

 these as well as others visible at Greenwich are as 

 follows : — 



The Planets. — Mercury is not observable this month, 

 the planet being in superior conjunction with the sun on 

 the '29th. 



Venus is in Aquarius, and forms a conspicuous object 

 in the eastern sky shortly before sunrise. She attains her 

 greattat westerly elongation of 46^ 12' on the 29th, on 

 which date she rises at 3.20 a.m., or Ih. 20m. before the 

 sun. 



Mars is in close proximity to the sun, and is therefore 

 unobservable. 



Jupiter and Saturn are both morning stars, the former 

 in Capricornus, the latter in Sagittarius. About the 

 middle of the month they rise at 3.0 a.m. and 2.15 a.m. 

 respectively. Being somewhat low down in the sky they 

 are not well placed for observation. 



Uranus is in Ophiuchus. About the middle of the 

 month he rises just before midnight and passes the 

 nieriilian at 4 a m. This, together with its small meridian 

 altitude of only IS'", makes it an inconvenient object for 

 observing. 



Neptune is jiractically in the same position for the first 

 few days of this month as is shown on the chart (in the 

 February number) for the former part of February ; now, 

 however, the motion is easterly. About the middle of the 

 month he crosses the meridian at 4.30 i-.m., after which 

 he will no longer be observable. 



Minima of Algol occur at convenient times on the 1st 

 at 11.57 p.M , 4th at 8.4<5 p.m., 22nd at 1.39 a.m., 24th at 

 10.28 P.M., 27th at 7^7 p.m.
