I spotted Venus between wispy strands of cirrus while the Sun’s lower limb was at least two to three semi-diameters above the distant horizon. After much pointing by me, MrsP spotted it just as the Sun’s lower limb touched the horizon, so one more tick in our 'I spy the stars' book. DaveP
What is the cut-off time for a "daylight" observation? I cannot see the horizon so I would use the sunset time from a sun app.
