V1413 AQL's AAVSO Sequence?   Message List

RE: [cvnet-discussion] V1413 AQL's AAVSO Sequence?

Good morning Mr. Bortle,

I just checked CHET (Chart Error Tools) through Blue and Gold and did not
see an existing problem report for charts or sequence on V1413, so may I
suggest that you submit one?
Clear skies,
Bob Stine (SRB)

Subject: [cvnet-discussion] V1413 AQL's AAVSO Sequence?





Having picked up V1413 Aql last evening for the first time this observing
season and using the latest AAVSO sequence, I would like to ask if others
find this sequence less than good visually. Actually, I felt it was
exceedingly poor. The 126 and particularly the 128 seem almost as bright as
the 123, while the 129 is dramatically fainter than either, yet very close
to the 131.

Thus, any estimated magnitudes of V1413 would seem to me highly dependent of
just what combination of comp stars are chosen, with widely differing final
magnitudes. This is particularly troublesome given that V1413 has a close
companion potentially influencing estimates and also that the star seems to
be entering a new active phase. Other's opinions?

Couldn't agree more with your comments John. I've used the 126 star only a handful of times, and I have no confidence in the brighter end of this sequence at...

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...

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...
