Seeing 6/10 Trans 8/10

[Vinicius Mansano Martins : Ribeirao Preto - SP,Brazil]

Conditions were initially poor but did improve somewhat as Saturn got higher,
although it is still behind the houses when it culminates!  Points of interest:
・Shading at the very far south.
・EZ quite bright,hints of a vague EB were indicated.
・NEB the most prominent of the belts,NEB(s) the darkest belt.
・NNTB seen but not as conspicuous as the NEB.
・A-Ring did show some interesting features,the out 2/3 of the ring was darker.
・B-Ring looked white tonight rather than yellow.
・C-Ring best seen at ansae edges.
・A field star is located not far from the Southern hemisphere.

The correct values are: CM1: 354.3° CM2: 80.3° CM3: 238.3°
[Paul G. Abel:Leicester:United Kingdom]
