Viewing the Seven Sister Cliffs from Worthing.

$Error correction and new lower detected lights for the previous viewing video. This video corrects a calculation made in the previous Viewing Brighton Seafront overer the sea from Worthing through a Nikon P510 video: This presentation shows videos of Brighton Seafront taken from a Nikon P510 camera on the evening of Tuesday 22nd October and Wednesday 23rd October 2018. The observations and science which can be tested and confirmed by anyone with a zoom camera who lives near the sea and willing to objectively employ the scientific method, prove that light does not refract in a downward direction over the sea in the evening under everyday, normal, non-specialised weather conditions and that we do not live on the globe as portrayed by the World Geodetic System, WGS 84 Globe / Ellipsoid model.$
