Congratulations on the century, Max! Very nice work, indeed.

Glad you enjoyed it, Alan. It was indeed an excellent meeting, which I was fortunate enough to attend in person, with interesting talks from David and Grant.

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

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

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.

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

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.

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

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

Good to hear the clouds have finally parted, Max.

Thanks Max. A very petite eclipse!

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

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

The digitally remastered images are truly remarkable

Impressive set up, Max. Looks very reliable indeed.

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

Yes, probably poor transparency and moonlight interference, Max.

Interesting to see them superposed on the brightening trend line

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