While most of the observers were out in the field, I stayed in the POD with the 28cm SCT at 70x, with the Kendrick full aperture solar filter in place. I concentrated on Venus' appearance between first and second contacts. I missed first contact because I was concentrating on the wrong limb. After I detected first contact, I tried to see Venus off the solar disk, but without success. Venus was extremely sharp, with fairly good seeing. I could see no trace of any atmosphere. Clouds obscured second contact, so I could not see whether the Black Drop was visible. Once Venus was fully on the disk, I went down to the field where François van Heerden and Dave Robitaille had set up a hydrogen alpha scope and Mallincam to record the transit and display it on a monitor for the people gathered. There were several other telescopes set up by those present.

Shortly after second contact the clouds closed in for good, except for a brief instant around 20:00, when the Sun peeped through with Venus still in transit.
