Hello! Here's a copy of a post I just posted in the AAVSO forum:
I'm quite new in the variable star business, though I've been an amateur astronomer for over three decades. I've been visually estimating variables for about a year now.
Last night, February 14th, 20.40 UT, I was trying to estimate the brightness of AA Aurigae with a 12" dobsonian at 90x and 169x, when I noticed something was off. Star 122 on the chart (X26200BCF) was as bright, or even a hair brighter, than 114! It was much brighter than stars 125 and 127. AA Aur itself was a little fainter than 114, but 122 was brighter than it, which obviously doesn't make sense.
So, obviously something is wrong here, if I'm not mistaken. A quick look at Digitized Sky Survey seems to show that 122 was indeed fainter than 114 at that time.
It's overcast here tonight and will likely be for the whole week, so I can't take another look until it clears again.
I ask of you to go out and take a look at the stars 114 and 122 near AA Aur (and of course also AA Aur, now that you're there anyway) and let me know what you see.
