Atmosphere remarkably clear. Got the Diffuse Light at 6" 30. About 6 h 52 m , the Stronger Light began to fade, 

 and also to spread upward a little. At 7" 7 m , could not distinguish it from the Diffuse Light. At 7 1 ' 30, no Stronger 

 Light; but the Diffuse Light very bright and distinct. Seemed to be more so than an hour before (the ecliptic 

 now making a larger angle with the horizon) ; its limits appeared to be the same as at 7 h . At 8 h , it was still very 

 bright. At 8 h 30 m , quite distinct. I now turned towards the east, to look for the moon's illumination.
