[[preprinted]] 104 [[/preprinted]] [[underline]] Saturday, June 1, 1912 [[/underline]] Spectra of variable stars for Prof. Russell 054231 RZ Aurigae magn. 9.5 Marked on I 24790 by Miss Masker from chart A.N. 174, 363 Indent. conf. by A.J.C. [[margin]] I 29863 Jan. 19, 1903 J.D. 6134.663 [[/margin]] I 29863 shows this star very ft. evidently at min. Max. light on I 24790. To determine its photog. brightness, I compared it with the prismatic comp. of +31° 1111 photom. magn. 6.72, therefore magn. of comp. = 11.72. The variable is estimate in [[strikethrough]] I 24790 [[/strikethrough]] I 24790 p.c. 2 var. on I 32337 p.c. 5 var. difficult because p.c. is so close to prismatic. Therefore, photog. magn. of RZ Aurigae is 12.07. Sp. in I 26507 too poor I 24024 narrow images but sp. can not be classied. Might be G or A I 13847 too poor [[end page]] [[new page]] [[preprinted]] 105 [[/preprinted]] June 1, 1912 [[underline]] 105461 [[/underline]] Probably too faint 12.2 at max. 113552 RW Urs. Maj. marked on I 10581 Sp. I 36031, too poor May be secondary star. I 31380 Cont. no lines seen. I 20239 G? I 30337, Apr. 19, 1903 J.D. 6224.657 On I 30337, the sp. is seen and star is evidently much fainter than on other plates. 113972 Z Drac. Sp. I 36598 too poor.
