AT 2026iul  - CV Type Transient

AT 2026iul (Cygnus) AT 2026iul (Type: CV) discovered 2026-04-07.397 UT by GEOTS Alias: GEOTS-PAPA-SHANKAR-2026-003 Discovery Magnitude 15.7 (Clear- Filter) vs Prior Non-Detection Limiting Magnitude 18 (Clear- Filter) Discovered in Cyg using 14" f/2.0 Astrograph at Golden Ears Observatory (MPC code U55). Group reports a significant brightening of the Gaia DR3 variable star 2033708559892804224 (VSX). Recent observations show an increase in magnitude of >2.3 when compared to the last recorded observation from Golden Ears Observatory on 02 March 2026. ( TNS 2026iul )

AT 2026iul - 2026-05-29 (T+51.6d) Image below (2026-05-29.015) was taken 51.6 days after discovery of 2026iul Position of earlier transient (faint) is shown by white cross-hairs Measured Magnitude +14.52 (Clear Filter)

Annotated CCD Image (100% size, linear scale, cropped) 5 x 60s exposure (average combine), 3x3 binning, Clear Filter 2026-05-29 00:24 UT (#1433026-30) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

NGC 5907  - Spiral Galaxy with Type II Supernova 2026kid

NGC 5907 with SN 2026kid (Draco) SN 2026kid (Type: II) discovered 2026-04-22.600 UT by Yasuo Sano Alias: ATLAS26equ, ZTF26aatswhm Discovery Magnitude 16.62 (Clear- Filter) vs Prior Non-Detection Limiting Magnitude 19 (Clear- Filter) SCT 0.36-m F/11 reflector + FLI ML1001E CCD, Nayoro Hokkaido Japan ( TNS 2026kid )

NGC 5907 with SN 2026kid - 2026-05-29 (T+36.4d) Image below (2026-05-29.002) was taken 36.4 days after discovery of 2026kid Position of earlier supernova (fading ) is shown by white cross-hairs Measured Magnitude +14.20 (Clear Filter) Poor quality image (due to bright sky background/cloud)

Annotated CCD Image (125% size, square root scale, cropped) 3 x 180s exposure (average combine), 3x3 binning, Clear Filter 2026-05-29 00:08 UT (#1433021-23) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2
