VSX ephemeris

Hello Joe,
You can use VSX to get an ephemeris.
Go to the star's page:

https://www.aavso.org/vsx/index.php?view=detail.top&oid=45170

In the Epoch field you will find a link called "Ephemeris".
By clicking on it you will see a list of eclipses with their times in UT.
You will have the start, mideclipse and end of the eclipse times.

The next one is on:

03 Jun 2020 19:40
04 Jun 2020 03:41
04 Jun 2020 11:43

I hope it helps.

Cheers,
Sebastian
