[vsnet-chat 7477] Antares (and delta Sco) faint

[Sebastián Otero]

Hi, all,
this might be of interest.
I had never seen Antares so faint. It is fading to a very faint minimum in its short term pulsation cycle but it is in the middle of a minimum of its long-term periodicity. This combination results in this very faint state. It is almost as faint as beta Crucis tonight (I made it V= 1.23).
You can see light curves in my webpage:

Delta Sco also happens to be in a faint state, almost reaching quiescence. The 60 d.-periodicity that was dominant over the past years seems to be disappearing. Is the star going to stop varying for now? V= 2.25 tonight. (My reported observations to the lists are 0.03 mag. fainter than V probably due to the emission lines. The stronger the H-alpha emission the larger the offset)

This means that the scorpion looks very much dimmer as a whole!

Best wishes,
Sebastian.
