In spite of the tiny size of the disk (2.31"), it was possible to catch 2
main features:
- a darker north hemisphere
- a bright area corresponding probably to the pole cap.
This is is a difficult observation due the confidential clearty of the disk,
but what appears at the 1st look was this bright area on the pole.
A bigger aperture should have to be used (probably more than 300mm(500x
magnification requested on); the seeing conditions was unusual for the
period with stable images during few seconds in spite of the low elevation
above horizon.
Indeed the contrast levels are well amplified for the report.
