cds-question@unistra.frap-starsvisible-astronomymedium-band-photometryDifferential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope of four magnetic Chemically Peculiar stars are presented. We refined the period of 63 And to 4.1890 days. The period of the sharp-lined Si star HD 192913 is 16.840 days, a value close to, but slightly different from published values. HR 8240, a sharp-lined Si star, is found not to be a photometric variable. Comparison of four color photometry of 108 Aqr by Morrison and Wolff and from the Four College APT indicates that subtle changes in the shapes of the light curves, especially that for u, have occurred suggesting that this star may be precessing.1994A&AS..103....1Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/103/1CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/106/333 : (stars alpha And, HD 184905, HR 8216, and HR 8434)J/A+AS/114/253 : (stars HD 11187, HD 14940, HD 15144, 20 Eri & HR 8933)J/PASP/109/9 : (stars HR 1643, Theta Aur, 49 Cam, and HR 3724)J/A+AS/122/249 : (HD 32633, 25 Sex, HR 7224 & HD 200311) (Adelman, 1997)J/A+AS/125/65 : (stars HD 37776, HR 2258, HR 6958 & 108 Aqr)J/A+AS/125/497 : (stars Theta Vir and 109 Vir)J/A+AS/133/197 : (33 Tau, HD 50169 and HR 7786)J/A+AS/134/53 : (HD 15980, HR 1094, 33 Gem and HD 115708)J/A+AS/136/111 : (HD 35298, 19 Lyr, HD 192678 and HR 8216)J/A+AS/136/379 : (45 Leo, HR 4330, 49 Her and HR 6718)J/A+AS/146/13 : (20 Eri, HR 1297, 12 CMa, and HD 134214)J/A+A/368/225 : (HR 5341, HD 142070, HR 6967 & HR 8434)J/A+A/390/1023 : (HR 194, HD 32966, HD 171782, and HR 7911)J/A+A/401/357 : (60 Tau, HR 1528, HR 8216, HR 8770)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/103/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/103/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/103/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/103/1https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/103/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/103/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/103/1/table1uvby photometry of 63 AndrecnoRecord number assigned by the VizieR team.
