Attached you'll find a lightcurve of the secondary minimum of delta Velorum based on visual observations from LIADA (Jaime Garc$ByB(B, Sergio Dom$ByO(Bguez and Sebasti$BaO(B Otero) and PEP(V) photometry from Brian Fraser (Astronomical Society of South Africa). From these observations we can now improve the numbers in IBVS #4999. Min II is clearly brighter (V= 2.20 +- 0.02) than Min I (V= 2.32 +- 0.05). The last two eclipses and Galileo's 1989 data are a good match with the published period that can be actually just a little longer (45.1502 days instead of 45.150). This will be known with future photometric studies. Best regards, Sebasti$BaO(B Otero, Buenos Aires, Argentina.
