V1413 AQL's AAVSO Sequence?   Message List  
Reply | Forward Message #1299 of 1370 |
Re: V1413 AQL's AAVSO Sequence?

Since most of the stars in this sequence are reddened, I've revised it to
exclude the known variables and suspects, and replaced the bluer stars with new
12th mag stars that are all similar reddish B-Vs to the rest of the comparison
stars.

I've retained the nearby 131 for ID purposes when the variable is faint. I'm not
married to this idea. It has a relatively high error also, probably due to
crowding.

I'd appreciate feedback from visual observers as to the 'improvements'. I can't
observe until I'm well again.

The culprit is the 123 comp, which is not only red (B-V= 1.9 over three nights) it is a variable and not part of the sequence!! This is an error propagated by...

... Quite honestly, Mike, I don't see the 12.3 as looking particularly off from its listed magnitude value. On the other hand, the 12.3 and 12.6 are almost...
