Note:

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.

  Note:

  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.
