EA, period not fixed. Two smooth eclipses, to about 80 percent and 78 percent of the normal light, each about 10 hours long.

What TESS shows

Two smooth eclipses, at BTJD 1773.889 (17 Oct 2019) and BTJD 3563.079 (9 Sep 2024). They are 1789 days apart and last about 10 hours. Many shorter periods still hide their other eclipses in the TESS gaps, so no period is adopted and the next eclipse is not predicted. A noisy patch near BTJD 3604 in sector 84 is not a third eclipse: the points jump up and down instead of making one smooth dip. A V = 8.7 star 67 arcseconds away does not fade. This one stays on the chart so it is not forgotten, and it is not ready to file.

Not ready for VSX. Two eclipses do not pick a period.

Next two eclipses

There is no date to publish. Two eclipses, 1789 days apart, leave too many possible periods.
