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!!!
