Sky nnt at the brightest ; but I was able to get reliable observations at the times noted in the chart. Tried again, 

 very carefully ;md repeatedly, from 9' 1 30"' to 9" 40'", to get boundaries ; but, thmigh the sky was now favorable, I 

 could not succeed. The Stronger Light was yet distinctly to lie seen, and senned to have travelled up as 1'ar as just 

 above Antares (as marked by dotted lines) ; but I could not determine this with certainty.
