The data was reduced with the Mookodi spectroscopic pipeline, and the resulting spectrum was analysed with SNID-Sage to extract a redshift of z=0.000426, which is consistent with redshift measurements of the SMC. We therefore classify AT2026oyp as a classical nova in the SMC with Fe II spectral characteristics, observed at an early stage of its eruption.

In particular, we identify Fe II emission lines at 4924 Å, 5018 Å, and 5169 Å, as well as He I emission at 5876 Å and 7065 Å. Additional emission features consistent with N III near 4638 Å and O I at 7773 Å are also present. The presence of strong Balmer emission lines together with Fe II multiplet lines suggests that the transient is consistent with a classical nova in the SMC. We therefore classify AT2026oyp as a classical nova in the SMC with Fe II spectral characteristics, observed at an early stage of its eruption.

In particular, we identify Fe II emission lines at 4924 Å, 5018 Å, and 5169 Å, as well as He I emission at 5876 Å and 7065 Å. Additional emission features consistent with N III near 4638 Å and O I at 7773 Å are also present. The presence of strong Balmer emission lines together with Fe II multiplet lines suggests that the transient is consistent with a classical nova in the SMC. We therefore classify AT2026oyp as a classical nova in the SMC with Fe II spectral characteristics, observed at an early stage of its eruption.

Booi (UCT/SAAO) BlackGEM Nova 1 BlackGEM We report the spectroscopic classification of AT2026noc obtained with the Lesedi 1.0-m telescope at the South African Astronomical Observatory (SAAO) equipped with the Mookodi spectrograph, Sutherland. A single spectrum was acquired on 2026-05-24 at 22:16:03 UTC with an exposure time of 600 s. The spectrum covers the wavelength range ~4000–8000 Å and shows a blue, steeply declining pseudo-blackbody continuum with prominent Balmer emission lines at rest wavelengths: Hα (6563 Å), Hβ (4861 Å), and Hγ (4340 Å), indicating a redshift of z ≈ 0 and confirming the transient is Galactic in nature. A rich forest of blended Fe II multiplet emission features (multiplets 42, 49, 74) is clearly detected between ~4800–5200 Å, superimposed on the continuum. 2026TNSCR2293....1M

A rich forest of blended Fe II multiplet emission features (multiplets 42, 49, 74) is clearly detected between ~4800–5200 Å, superimposed on the continuum. Based on the strong Balmer emission series at rest wavelengths, the presence of characteristic Fe II multiplet blends, and the hot blue continuum, we classify AT2026noc as a Galactic Classical Nova of the Fe II spectroscopic class (Williams et. al. 1992).

O'Neill GOTO SN II 0.014577 1 GOTO Good template matches to young Type II SNe, matching the current age of the transient (<5d from explosion). As the spectrum does not exhibit any narrow host galaxy lines, the redshift is unclear but likely low (z<0.015) given the brightness of the event and the best spectral fits. We assume the redshift of the brighter nearby galaxy, MCG-03-28-017, towards South East of the SN (0.014577, NED), but emphasise that the actual host galaxy may not be found at the redshift. 2026TNSCR1811....1P

The spectrum confirms the nova classification, displaying strong Balmer emission (Hα, Hβ, Hγ), Fe II emission multiplets (λλ4924, 5018, 5169), and He I λλ5876, 7065, consistent with an Fe II-class classical nova. We additionally detect He II λ4686 and the N III Bowen blend at ~λ4640 in emission, indicating the nova is transitioning toward the nebular phase with a significant ionizing flux from the hot white dwarf. The O I λ7773 feature is also present. The overall spectral morphology is consistent with a classical nova in the Large Magellanic Cloud, corroborating the classification reported. 2026TNSCR1378....1M

The data was reduced with Mookodi spectroscopic pipeline, and the resulting spectrum was analysed with SNID-Sage to extract a redshift of z = 0.00087, which is consistent with redshift measurements of the LMC. The spectrum shows prominent Balmer emission lines, including Hα, Hβ, and Hγ, together with several metal lines characteristic of early-time nova spectra. In particular, we identify Fe II emission lines at 4924 Å, 5018 Å, and 5169 Å, as well as He I emission at 5876 Å and 7065 Å. Additional emission features consistent with N III near 4638 Å and O I at 7773 Å are also present. The presence of strong Balmer emission lines together with Fe II multiplet lines suggests that the transient is consistent with a classical nova in the LMC. We therefore classify AT2026fbz as a classical nova in the LMC with hybrid (Fe II / He–N) spectral characteristics, observed at an early stage of its eruption. 2026TNSCR.991....1M

Burns (Carnegie) NUTS2 SN II 0.017 1 NUTS2, POISE Photometric follow-up by POISE using the 1-m Swope Telescope indicates that supernova 2025yrt reached a peak absolute g-band magnitude of −18.4 mag (corrected for Milky Way reddening) approximately 10 days after discovery. The source has since declined to −18 mag, consistent with the post-maximum behavior of a moderately luminous Type II supernova. 2025TNSCR4076....1K
