Since 1986 variable star T UMi
did experience slow and steady change
as shown on two LCs.
My modest contribution to the light-curve
is also present.
To variable star designated as LPV
I think this change is rather remarkable....
best regards

Wow, the range in brightness is getting a lot smaller. That is cool looking, thanks for the info.

There's a small but interesting article in the December issue of S&T on T UMi. You'll definitely want to read it. cool.gif

Just to fill the gap for others...the article is on page 10 of the December, 2019 Sky and Tele..."A Century of Amateur Observations Sheds Light on Stellar Evolution", by Monica Young. Pretty interesting and informative piece.

Experiencing cloudy weather is time to go
through old records checks.
Just find interesting record for S Per
with amplitude change.
with best regards
