[vsnet-alert 5352] RV: PRIMARY ECLIPSE

Dear vsnet friends and everyone involved in delta Velorum observing
campaign:

We're just hours away of the expected primary eclipse of delta Velorum.
Last saturday I observed what seemed a little fading, but it was probably
observational error. Tomorrow night will be a very important step in
confirming the 45.164 day period. But remember we have to wait until
November 21st for a complete confirmation.
Given delta's position in the early morning sky, the comparison star
sequence suggested is:

1.70 gamma Velorum
2.24 iota Carinae
2.25 zeta Puppis
2.49 kappa Velorum

The event should be visible throughout the night for most of us. Predicted
times are:

Beginning:   JD 2451850.19    1 de noviembre 16.35 UT
Mideclipse: JD 2451850.64   2 de noviembre 03.20 UT
End:              JD 2451851.09   2 de noviembre 14.10 UT

It's cloudy in Buenos Aires, so I'll probably not be able to watch the star. I hope you all have better luck!!!

Best regards,
Sebastian Otero,
Buenos Aires, Argentina.
LIADA.
