ZWO Seestar S30 Pro: 30 mm aperture, 160 mm focal length, alt-azimuth. Sony IMX585 colour CMOS (Bayer). No filter wheel; photometry from the green channel, reported as AAVSO band TG.
Fitted with the VarAstro tool over JD 2461262.8319-2461262.8804. This night has only about 15 minutes of lead before the minimum, which is too little for a Kwee-van Woerden fit in our own pipeline to be independent of its seed, so our adopted epoch comes from a template fit instead: 2461262.84303 +/- 0.00193 d, agreeing with this value to 0.95 min (0.33 sigma). Our own KvW attempt returned 2461262.84137 and was discarded; this fit sits 3.4 min from that and 0.95 min from the template value, which supports the template. Given the short lead, treat the formal error here as optimistic. Both BJD_TDB. Same fixed nine-star ensemble as our other nights; ZWO Seestar S30 Pro. AAVSO observer code VDBA.

357 points, ZWO Seestar S30 Pro. Differential photometry against the same fixed nine-star ensemble as our 2026-08-03 and 2026-08-08 observations, each comparison vetted against VSX and Gaia for variability. Magnitudes are instrumental differential with an arbitrary zero point, not standard-transformed. Times are BJD_TDB. Note that this night has only about 15 minutes of lead before the minimum, which is too little for a Kwee-van Woerden fit to be independent of its seed; our own epoch for it comes from a template fit rather than KvW. Uploaded as photometry for the record. AAVSO observer code VDBA.

ZWO Seestar S30 Pro: 30 mm aperture, 160 mm focal length, alt-azimuth. Sony IMX585 colour CMOS (Bayer). No filter wheel; photometry from the green channel, reported as AAVSO band TG.
Fitted with the VarAstro tool over JD 2461260.8752 onward, deliberately excluding the maximum earlier in this 5.5 h window; fitting across it moved the result by 7 minutes. An independent Kwee-van Woerden fit of the same curve in our own pipeline gives 2461260.91902 +/- 0.00116 d, agreeing with this value to 12 seconds (0.11 sigma). Both BJD_TDB. Instrumental differential magnitudes against the same fixed nine-star ensemble as our 2026-08-03 observation; ZWO Seestar S30 Pro. AAVSO observer code VDBA.

540 points, ZWO Seestar S30 Pro. Differential photometry against the same fixed nine-star ensemble as our 2026-08-03 observation, each comparison vetted against VSX and Gaia for variability. Magnitudes are instrumental differential with an arbitrary zero point, not standard-transformed; the shape of the curve is unaffected. Times are BJD_TDB. Our own Kwee-van Woerden fit of this night gives 2461260.91902 +/- 0.00116 d, an O-C of -3.10 +/- 1.67 min against a TESS quadratic ephemeris, a residual of +0.11 sigma. AAVSO observer code VDBA.
