 quarters, perhaps moonlight, perhaps A.B.

 less, with some streaming. I saw no streamers higher than 10°. At 9h and after cloudy. 



Feb. 16th. — Slight and uncertain until about 9h 30m, when and after to lOh, it was plain ; but 

 then only an illumination along N. horizon, ami^litudc 40", altitude 2° or 3°. I saw no streamers.
