But please forgive me when I ask you of your opinion of other estimates that have been made on www.aavso.org by probable amateur astronomers.
It seems that most observers get a different magnitude when compared to you and me.
Some are using binoculars; whereas others refuse to inform us of their instrument.
Ignoring those who use a V filter, their estimated magnitudes hugely vary between +5.7 to +7.1 over the last 7 days.
Hi Aubrey - To see such a difference in reports on the brightness of LPV stars is to be fully expected,
as each observer will have their own personal equation. I think it's just coincidence that are recent observations are
very similar.
Years ago when I was doing a lot of variable star work, my own personal equation was around 0.3 mag. i.e. I would
report an estimate that would be 0.3 mag (average) brighter than the ten-day mean of a preliminary light-curve
of the LPV star under observation. I have no idea what it might be today, or if it has changed over time as I have aged.
Maybe when I have the time I could sit down and do a lot of number crunching to find out, however I'm not doing
the level of variable star work (estimating) that I was some 30 years ago.
Back in the day, I remember light-curves being produced from weighted observations, these would help smooth
out some of the variations in the light-curves.
