Star 4's value has been confirmed on the basis of PEP(V) kindly supplied by the Geneva Observatory. In order to incorporate the considerable additional data reaching us from abroad we have adopted the following secondary sequence stars: z1 'A' of AF Cyg V=5.20 z2 Fl 57 Cyg 4.80 z3 Fl 51 Cyg 5.39 z4 SAO 32862 4.51 z5 Fl 23 Cyg 5.14 z6 Fl 26 Cyg 5.05 z7 Fl 20 Cyg 5.03 z8 Fl 43 Cyg 5.69 z9 SAO 32649 6.18 The following extended sequence and e-chart should now be used, in preference to other comparisons, under ref N/019.03: \\\\\\NovaCyg92 b Discovered by Peter Collins P,20h 29.1m +52 28' (1950) S,120,30,S O,60,60,4.4,18.0B -L,R,NOVA -S,N/019.03 R,7.54,59,100,G,A R,7.90,99,13,6,B R,8.58,2,13,7,A R,8.74,34,12,H,A R,9.01,56,65,K,A R,9.52,97,28,L,A R,10.07,59,65,M,R R,10.63,50,85,N,L R,11.17,62,46,P,A M,6,75,98 M,7,118,37 M,8,112,40 M,9,82,98,27,94,60,16,78,68 M,10,44,28,25,27,100,65,21,59,79,9,85,10 M,10,13,47,56,21,16,47,65,14,21,94,63,118,72 M,10,3,8 M,11,108,114,51,96,99,85,80,81,101,114,104,110,102,116 M,11,10,91,42,98,91,100,69,75,52,90,104,81,114,101 M,11,82,91,90,112,81,116,61,91,65,89,60,96 M,11,97,102,90,105,97,102,90,105,108,33,29,11,39,20 M,11,106,61,16,54,76,37,98,18,103,11,48,11,41,42 M,11,44,49,35,67,17,23,70,51,8,75,23,72,91,66 M,11,25,60,105,25,110,45,5,19,49,40,38,65, M,11,40,45,107,61,60,13,2,72,19,31,61,70,3,73 M,11,111,49,94,67,91,56,5,53,59,6,68,4,76,3 M,11,28,7 E,93 ////// Basic chart automatically generated by GSC2FIND ver 1.1 Guy M Hurst
