AstroNote 2026-102

We report photometric observations of the young supernova SN 2026fvx obtained at the Stone Edge Observatory. Imaging was conducted on 2026 April 6 and April 8 UT using g, r, and i filters, with exposure times of 200 s (April 6) and 100 and 200 s (April 8). The data were reduced using a pipeline incorporating dark and sky subtraction, and photometry was calibrated using APASS magnitudes of stars in the field.

We measure consistent magnitudes across multiple epochs. On April 6 we combine two measurements to obtain mean magnitudes of g ≈ 13.14 (04:42-05:06 UT), r ≈ 13.06 (04:47-05:16 UT), and i ≈ 13.43 (04:56-05:23 UT). On April 8, combining three independent measurements per filter taken across two observing sessions, we obtain g ≈ 13.06 (04:26-08:28 UT), r ≈ 13.01 (04:29-08:21 UT), and i ≈ 13.35 (04:33-08:33 UT).
