I am not an expert in variable Stars and also not in photometry.
I normaly make astrometry of minor planets.
On a series of 18 old frames (October 2011) taken in a total
duration of about 1 hour at Taunus Observatory (60cm Cassegrain+SBIG 11000)
I have seen a variable Star changing brightness. I found out
it is V480 Tau. V480 Tau should have an amplitude of 0,04mag and has a brightness of 5mag.
But for my eyes the amplitude seems to be higher.
Please have a look at my animation here:
I did not analyse the frames, because Iam not an expert of photometry
and for the astrometry software, which I use, such a wide apertur was not possible.
My question now is: Is that what you can see in the animation the normal fluctuation of 0,04mag?
Does anybody want to have the 18 frames for analyse or is it not so important?
