Observation geometry of Venus during May 2012. Blue cross represents the anti-solar point. Green circles are the observed locations, (left) 33SLT3 (33° S, 3:30 LT) and (top) 67NLT0 (67° N, 00:00 LT). Their sizes are the field of view (0.9 arcsec). The angular diameter of the apparent disc varied between 50.4 arcsec on May 19 (shown in this figure) and 52.5 arcsec on May 22
