The Greek letter "Chi" is expressed as "x" in lower case and "X" in upper case. However, we then have HIP 48662, which is designated as "X" Velorum, which is contradictory to the original Bayer designation for HIP 52154, in upper case. Of course HIP 48662, got it's designation of X Velorum, a few hundred years after the original.

I observed both "X" Velorum's a few minutes ago! Capital X Velorum the red carbon star as well as small x Velorum the double star. x Velorum is beautiful, I saw blue and gold components. I can see now why it is your favourite double John
Thanks for recommending it!
