Abstract:
This report includes classifications of one Type IIn SN (AT2024egc).

ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (Smartt et al. 2015 2015A&A...579A..40S), reports the following supernova classifications.

The target was supplied by BlackGEM (https://astro.ru.nl/blackgem/).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2024 March 14, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using GELATO (Harutyunyan et al. 2008 2008A&A...488..383H).

The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

The classified objects are listed in the Related Objects table below.

Catalog Name Reported RA Reported DEC Reported Obj-Type Reported Redshift Host Name Host Redshift Source Phase (days) Remarks TNS RA TNS DEC TNS Obj-Type TNS Redshift
TNS 2024egc [BGEM J191145.30-570804.0] 19:11:45.308 -57:08:04.06 SN IIn 0.01 ESO184-G025 0.01 BlackGEM IIn. Narrow Balmer P-Cygni profiles superimposed on a broader emission component. GELATO provides good matches to the peculiar Type IIn SN 2009ip at 6 days past UV maximum light. Known host redshift z=0.010. 19:11:45.308 -57:08:04.06 SN IIn 0.01014
