TYC 3987-00764-1 · Gaia DR3 2006430088714032000 and 2006430084414311168 · 2MASS J22290774+5456088

Position: 22h 29m 07.77s, +54° 56′ 08.8″
V magnitude: 12.13
Where: 91 arcmin east of V345 Lac, in the 1.50–1.60° ring
Signal: One eclipse, two stars 0.75 arcsec apart, 4.53 days. About 0.13 mag in the TYC star’s aperture and 0.11 mag in the other. The host is not assigned.

What TESS shows

TIC 415460747 and TIC 2015971564 are 0.75 arcsec apart. Both apertures fade on one clock. Twenty-seven minima of the TYC star give

Min = BTJD 2855.58848 + 4.533641 E

The TYC aperture falls by 0.13 mag. The other aperture falls by 0.11 mag. The time below 98 percent is 4.5 hours, and the time below half depth is 3.4 hours. The times scatter by 19 minutes rms. The largest residual is 47 minutes. No secondary is adopted. Gaia’s solutions for the pair are poor, and TESS cannot say which star fades. The note is not a VSX submission.

Finder chart

Real sky images (DSS2 red) with Gaia DR3 stars overlaid. North is up, east is left, J2000. Red tick marks point at the target (Gaia DR3 2006430088714032000, G = 12.72). Gold squares C1 to C5 are comparison stars of similar brightness. Tap an image for the full-size printable chart.

Wide finder, 30 × 30 arcmin, for star-hopping.

Close finder, 8 × 8 arcmin, to pick out the target.

Neighbor that also fades: TIC 2015971564 (Gaia DR3 2006430084414311168, G = 12.54) sits 0.75 arcsec away at position angle 244° and fades on the same clock. It is the magenta diamond marked N. Measure it in its own aperture, separately from the target.

Comparison stars are within about 1 mag of the target in Gaia G, have similar color, no close companion, and no VSX entry within 10 arcsec. Images: DSS2 red (POSS-II, STScI Digitized Sky Survey). Stars: ESA Gaia DR3.

VSX

Not filed. New addition from the 1.50–1.60° ring, 28 Oct 2026. One page for the pair. The host is not assigned.

Next two eclipses

Eclipse 12 Nov 2026, 15:40 UTC · 2 Nov, 07:40 PST Pacific · 2 Nov, 16:40 CET central Europe
Eclipse 27 Nov 2026, 04:28 UTC · 6 Nov, 20:28 PST Pacific · 7 Nov, 05:28 CET central Europe

These times are the blended eclipse. The fade lasts about 4.5 hours, and the middle can be off by about an hour. Use two apertures, one on each star of the 0.75-arcsec pair. The largest residual is 47 minutes.

Help with a measurement

The useful measurement is two apertures, one on TIC 415460747 and one on TIC 2015971564, 0.75 arcsec apart. A blended aperture only repeats TESS. Pick a date if you can try.
