I just thought I would take this opportunity to describe my recent experience of observing a completely new carbon star which is also a variable star. Its designation is KL Andromedae.
Its magnitude varies from 10.4 down to 13.5.
Having a William Optics 158 mm F/7 apochromatic refractor on a Berlebach Planet altazimuth mount, I had little problem star hopping to KL And from the glorious binary Almach (Gamma Andromedae). In my personal notes, I found KL And a very attractive intense dim orange carbon star with a magnitude of 10.8. This implies that the star is near its brightness at the moment.
Because Andromeda is getting a little low in the north western sky, I won't be able to estimate its magnitude for very much longer until September or October 2018 at the earliest.
But perhaps a few other variable star admirers might find the time to observe KL Andromedae before it sinks too low.
The colour will win you over instantly for sure.
Clear skies from Aubrey.
