You are all invited to join a live “EB discussion” webinar on this Wednesday, April 15, at 12 noon PDT = 3PM EDT = 1900 UT.
This was prompted by the question "How do you plan eclipse observations, especially for systems with long periods (> few days) and possibly-uncertain ephemerides?"
The tentative agenda is:
• Gary Billings enjoys stars with little observational history, so the ephemerides can be so far off that an all-night run on the appointed night sometimes detects no fade at all. He’ll describe his approach and some examples.
• Eric Dose will describe how he has recaptured a few EB phases from scratch, without tying up nights of scope time.
• Sebastion Otero will show how to search VSX for eclipsing binaries without published periods,
• If Gerry Samolyk is on-hand, he will be interested in hearing what you like about the current EB-Section website, and what you would like to see added or changed.
We’re planning on a one-hour session, but it can be extended a bit if the discussion stays active.

There is no charge – all are welcome! We look forward to seeing you.
this is a great idea. I've just registered for the webinar and look forward to the discussions, although the 5am local time start will be a little inconvenient. That's the problm with a non-flat earth, but coffee will help. Cheers,
I will try to record it ... but whether the recording is ever made public will depend on the quality (I'm a neophyte at this) and on the concurrence of the presenters. We'll decide after we've reviewed the recording.
I can't rearrange existing plans, so I can't make it. I understand a recording has the disadvantage of not asking questions, but something is better than nothing.
The presenters have given their informed consent, so the recording of the “EB Discussion Webinar” (4-15-2020) is now available on line. Go to: https://youtu.be/QKPXhMpz9wk.
(This version has been very lightly edited: I removed a few clips where we were fumbling to get the presentations set up).
Hi Bob and all the presenters,
Thanks for organising the webinar last week. I enjoyed each of the talks and picked up a few good tips. I've had a quick look at the YouTube video, the quality is excellent. It'll be a great resource for those who couldn't participate in the live event.
Thanks Gary for making your slides available too. Cheers,
Gary's presentation (post #8 above) includes a mention of my JAAVSO paper on O-C diagrams.
Table 2 in the paperr contains O-C values that do not match those in the O-C diagram in Figure 2. The problem was I copied and pasted the wrong table into the manuscript! Everything else in the paper is correct.
The correct table is attached, and will appear as an erratum in a forthcoming issue of the Journal.
