When I said "no changes" I meant "the same as my last observation in
october". SO THE STAR DIDN'T FADE, and that is very interesting.
It's funny to note that both deltas have the same amplitude but in reverse:
while delta Sco rises to 1.9 from 2.3, delta Vel falls from 1.95 to 2.3.

It's still difficult to be accurate with delta Sco because of the lack of
good comparison stars and its low altitude. We'll have to be happy with our
1.9 -2.1 observations until the star gets higher.

Cheers,
Sebastian.
