Hi All

 

The little observed RCB star, IO Nor, appears to be in the initial stages of a fade.  Last year before solar conjunction it hovered around mag 11.5.  I picked up it up again in mid February this year where it had faded to mag 12.5 and over the last couple of weeks it's faded further to mag 13.2.  I've got no idea if this will be a full fade and indeed what a full fade really means for this star as it just has not been observed before.

 

In the old days it used to be a pretty big deal when RCB stars underwent a fade.  That doesn't appear to be the case now, I suppose it depends on what interests the professionals at the time.

 

Regards
