This was the best eclipse I could observe up to now. The star was well-positioned during totality and the night was pretty clear. Reanalysing Galileo's data of the secondary eclipse, it's possible to establish it was a total eclipse. This is consistent with last night's observations: there is a flat bootton also in the primary eclipse. Previous eclipse observations were influenced by the notion of "it can't be this faint" ;-)) and the discovery of something that I thought it couldn't be that conspicuous. The fact is that delta Velorum eclipses are rather deep: I = 2.46 (estimated error 0.05) II= 2.27 (estimated error 0.03) Yesterday it was a great show to find the star that dim during all the night. Sometimes delta Velorum is the brightest star of the False Cross (when epsilon Car is exactly at its minimum in V= 1.96) Last night it was almost the faintest, almost as faint as kappa Velorum (V= 2.49) VELdelta 20030607.915 2.26 OSE VELdelta 20030607.922 2.29 OSE VELdelta 20030607.938 2.33 OSE VELdelta 20030607.952 2.37 OSE VELdelta 20030607.968 2.40 OSE VELdelta 20030607.981 2.42 OSE VELdelta 20030607.990 2.43 OSE VELdelta 20030607.998 2.45 OSE VELdelta 20030608.010 2.46 OSE VELdelta 20030608.022 2.46 OSE VELdelta 20030608.029 2.46 OSE VELdelta 20030608.038 2.46 OSE VELdelta 20030608.056 2.46: OSE VELdelta 20030608.075 2.46: OSE Well-done photoelectric or CCD observations would help a lot.
