A Living Catalog of Novae in the Small Magellanic Cloud

Scope of the Catalog: A table of novae in the Small Magellanic Cloud (SMC) going back to the first recorded nova in 1897 was compiled by W. Pietsch and posted on the Max Planck Institute for Extraterrestrial Physics (MPE) webpage (MPE SMC Catalog). That catalog was last updated in September 2021. My purpose in the following table is to continue the SMC nova catalog in an abbreviated form, and to correct it where later work allows. The first part of the table lists the 26 optical nova eruptions, plus two unconfirmed candidates (SMCN 2025-08a = AT 2025yid and SMCN 2026-09a = AT 2026ably, whose designations I have assigned and are not official); the second lists four supersoft X-ray sources in Be+white dwarf binaries that showed no optical nova outburst and are not counted as novae.

At present, I give the nova name, the JD of the discovery, the equatorial coordinates (J2000), the reported maximum magnitude and filter, the spectroscopic class (where known), notes, and references. The magnitudes are as reported and are not necessarily the true peak; "<" marks cases where the maximum was missed, and ":" an uncertain value. Filter codes are pg (photographic), w (unfiltered), and standard band names; ? means no filter information is available. The Type column gives the spectroscopic class, based on the Fe II and He/N classes of Williams (1992), where one has been published, as given in the original references: Fe II; He/N; Hybrid (Fe IIb systems displaying broad He and N lines); and Nova (spectroscopically confirmed as a nova, class not given). A question mark indicates an uncertain class, "X or Y" an ambiguous one, and a blank entry means that no class is available. Positions, dates and magnitudes through 2020 are from the MPE catalog except where noted: positions for the novae of 1897–1952, 1974-08a and 1986-10a are from Morel (2021), and those of 1897–1952 differ from MPE's by 17–41" (by 16′ for HV 849); and the dates of 2004-06a and 2006-08a and several maximum magnitudes have been revised from the original sources, as noted in the table. A machine-readable version of the table, with units and column descriptions, is available in astropy ECSV format as smc_nova_table.ecsv, and as a plain CSV file for spreadsheets, smc_nova_table.csv.
