Note: Mira (Omicron Ceti) is brightening rapidly, currently by
  nearly 0.25 mag. per day.

Observers:
GRL = Bjorn H. Granslo (Blindern, Oslo, Norway). Instruments: 70-mm
  refractor (L70), 10x50 binoculars (B10x50). Partly cloudy. AAVSO
  sequences were used. Venus was observed for a few minutes before
  it set. Green flashes were visible in the telescope and Venus
  appeared red and dimmed by 6.5-8.0 mag. (slowly fluctuating) due
  to the strong extinction. Its apparent brightness was compared
  with stars near zenith. When Venus set at 16h56m UT its true
  altitude was -0.6 deg., i.e. below the astronomical horizon.
