cds-question@unistra.frnovaevariable-starsphotometryvisible-astronomyA program of long-term ground-based photometric monitoring of 134 old novae and novalike cataclysmic variables (CVs) has been concluded. In this paper, we display, analyze, and discuss the light curves of 33 of these targets, which have shown "stunted" outbursts (StOBs) during the years 1990-2014. Because our light curves have long time baselines and strong homogeneity, most of our analysis centers on the aggregate properties of StOBs to take advantage of the strengths of our data sets, as opposed to more detailed analysis of individual systems. The StOBs amplitudes exhibit a range of ~0.14-1.35mag, with a peak near ~0.55mag and durations in the range of ~5-50days. We have provided additional targets including FY Per, X Ser, CT Ser, and BK Lyn. A few Z Cam stars were also monitored, providing a photometric comparison of Z Cam and StOB stars at a common cadence and sampling. We refine the properties of the small StOBs and better characterize their relationship to somewhat similar photometric features in Z Cam-type dwarf novae as well as IW And-type and AH Pic-type phenomena. We also compare our ground-based photometry of four CVs displaying StOBs with results from published Kepler mission photometry. The dense spacing and high precision of the Kepler data reveal faint excursions (dips) that are numerous for some CVs, while the ground-based data cover a wider range of CV types. Ultimately, we find that our data provide evidence for both accretion disk instabilities and rapid mass transfer modulation episodes as probable StOB contributing mechanisms.2025ApJS..277...29Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/277/29CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-)B/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)V/94 : Catalog and Atlas of Cataclysmic Variables (Downes+ 1997)V/110 : Catalog of Cataclysmic Variables (Downes+ 2001)V/123 : Catalog of Cataclysmic Variables (Downes+ 2001-2006)II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)J/PASP/107/324 : Northern CV secondary photometric standards (Henden+ 1995)J/PASP/109/441 : Northern Cataclysmic Variables (Henden+ 1997)J/AJ/123/3460 : Low-amplitude variables in NGC 6791 (Mochejska+, 2002)J/MNRAS/409/1470 : Kepler compact pulsator candidates (Ostensen+, 2010)J/PASP/125/126 : Light curve of CR Boo over 1990-2012 (Honeycutt+, 2013)J/AJ/147/10 : Light curve of V794 Aql over 1990-2012 (Honeycutt+, 2014)J/AJ/147/105 : Light curve of HR Lyr over 1991-2012 (Honeycutt+, 2014)J/MNRAS/460/2526 : Dwarf novae outbursts properties (Otulakowska-Hypka+, 2016)http://vsx.aavso.org/ : International Variable Star Index homepagehttp://archive.stsci.edu/prepds/cvcat/ : The Catalog and Atlas of Cataclysmichttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/277/29https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/277/29http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/277/29https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/277/29https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/277/29http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/277/29GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/277/29/table2 (The 38 Morgan-Monroe Observatory (MMO) targets used in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/277/29/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/277/29/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/277/29/table2?GETtext/xml+votable180.050000true332.2740056-3.77158030.0055555555555555566/511 928 1535 1848 2154 3923 4040 4052 4279 4348 4990 5129 6567 8474 9238 9578 12896 13975 14226 14254 14293 14498 14847 17722 18229 19009 19639 21705 22129 22890 23432 26780 30001 30521 30788 30970 30993 31774https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/277/29?format=asciiOpticaldefaultJ/ApJS/277/29/table2The 38 Morgan-Monroe Observatory (MMO) targets used in this paper_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainONameOther identifiermeta.idcharTypeVariability type (1)meta.notecharVSXVSX type (2)meta.code;src.varcharSeasApproximate number of season(s) the target was observed (3)meta.number;obscharCampCampaign as defined in Table 1 (4)meta.id;obscharFiltFilter (V or C)meta.id;instr.filtercharLCInteractive LC Plotmeta.ref.urlcharSimbadNameSimbad column added by the CDSmeta.idcharnullableEns[5/326] Number of ensemble stars used in the AstroVar solution (see Section 4.2)meta.numberintrecnoRecord number assigned by the VizieR team.
