Thanks Max. I suspected this was the case. But ignoring these, the O-C is looking good 👍🏻

[Jeremy Shears]

Looking good Max. Any ideas about outliers? I’ve sometimes struggled to assign proper ToMs in specific eclipses, especially small ones, when the underlying light curve has been busy with bumps and humps.

I tried accessing some recent VSNet posts yesterday, but also timed out

[Jeremy Shears]

Period analysis can be performed using one of Peranso spectrum analysis tools. But these analyse the data globally, resulting in significant periods being identified, rather than calculating the ToMin that would be required for O-C analysis.

[Jeremy Shears]

Hmmm…that is very odd Max. Could it be the recent dip is a random fluctuation rather than an eclipse?

[Jeremy Shears]

Definitely worth pursuing your lead about outburst amplitude relative to previous and successive brighter outbursts, Max. Correlations were found by Frank Bateson regarding normal outbursts between superoutbursts in the UGSU system, VW Hyi.

[Jeremy Shears]

Good to see you back in action Max. Sounds like you’ve had a rough patch.

[Jeremy Shears]

Latest reports on VSNet suggest that RY Sgr is fading rapidly. Latest obs by Jose Ripero on Sep 26.895 place it at mag 9.7

[Jeremy Shears]

Good to hear the clouds have finally parted, Max.

[Jeremy Shears]

Thanks Max. A very petite eclipse!

[Jeremy Shears]

Looks like normal service has been resumed, Max! 👍🏻

[Jeremy Shears]

Nice to see you continuing despite the inclement wx, Max.

[Jeremy Shears]

The digitally remastered images are truly remarkable

[Jeremy Shears]

Impressive set up, Max. Looks very reliable indeed.

[Jeremy Shears]

Welcome back, Max. I was getting worried! Good to see that data have been collected in the meantime

[Jeremy Shears]

Yes, probably poor transparency and moonlight interference, Max.

[Jeremy Shears]

Interesting to see them superposed on the brightening trend line

[Jeremy Shears]

That is a dramatic eclipse Max! Seems to be enhanced by the preceding hump.

[Jeremy Shears]

Looks slightly shallower, as expected, Max

[Jeremy Shears]

I see the dilemma, Max (also shows rage pitfalls CV observers can get into with less than ideal data). If you can confidently and consistently compensate that would be the way to go (sorry!). In any case, it would be important to identify those eclipses where there is some kind of uncertainty in assignment of type.
