Remarks. 



Night as preceding. The meridian circle observations show that this is the right star. Comparing it with H. C. 15707, it is a full magnitude 

 smaller, so that the estimate of last night is correct. There is a star rather brighter in the same parallel with Mars, and following about 1m.
