tass star 240.0543 +9.3849
Last night I got 3 ea 48 frame 100 second runs. I have cut down the number
of images I take to get away from looking at the roof. This should make
things a little more stable. The first run did not make it through the
pipeline for no obvious reason. The second run produced the star of the
subject line. I am still processing the third run.
This is the first time I have met my goal of releasing a measurement within
24 hours. I could not find the star in VizieR. At least nothing seemed
close to me. This measurement is roughly 22 hours old.
tass star 240.0543 +9.3849 Vmag 10.12 Imag 9.64 (mean values for 2 hour run)
The magnitude decreased linearly (brightened) through the run changing by
0.3 mag in V and I.
I am slowly working out the bugs in the reduction process. I see no reason
not to be able to put candidates on a web site within 24 hours. I know
some will think this is not proper science. But it is good fun, and having
fun with the data does not change the quality of the science.
Later I will consolidate everything and write a proper paper on all this
data. So I am saying nothing more about this star other than it was
observed to slowly change 0.3 mag in two hours.
This is about par for the course. I find about one interesting (fast
changing) star per thousand measured. There are more, I am sure, but these
will take a lot more measurement care. Many of the slower variables will
be found as we observe over time.
