XL VI GEELMUYDEN. ASTRONOMICAL OBSERVATIONS. [NORV. POL. EXP. 



Table c (concluded). 



NOTES TO TABLE c. 



1. Decrease of brightness very slow; took the moment when it was as usually 

 at R. 



2. Was not prepared for so early a reappearance, but Sat. very feeble when the time 

 was noted. 



3. Sat now so feeble that I was not sure of its visibility. 



4. Sat. close to Planet's limb, and some haze, perhaps J /4 or Va minute late as com- 

 pared with D. 



5. Sat barely visible when I knew that it was there. Perhaps visible '/a 8 /4 m ' n - 

 longer. 



6. About same brightness as at D; R sharper than D, but, on the whole, observa- 

 tion of this Satellite uncertain, owing to the slow motion. 



7. Followed the Sat. further, as I was not quite sure ; 30 s later nearly of the same 

 brightness as the other Satellites. 



8. Saw the Satellite very feeble in the moment I put the eye to the telescope. 

 Could perhaps have seen it 10 s before. 



9. Not a good observation; too late.
