Ayani, Bisei Astronomical Observatory (BAO), Okayama; and H. Kawakita, Nara, Japan, report that a spectrogram (range 380-730 nm, resolution 1.3 nm; 20-min exposure) of SN 1995al obtained on Nov. 4.77 UT with the BAO 1.0-m telescope confirms the results obtained by the Beijing group: "Absorption features of Si II (635.5 nm), S II (545.4 nm), and Mg II (448.1 nm) and complex absorptions of Si II and S II short of 500 nm are clearly seen. Balmer lines are absent, and the Si II 597.2-nm absorption line is still weak, indicating that this is type-Ia supernova at maximum; this spectrum resembles that of SN 1981B at maximum (Branch et al. 1983, Ap.J. 270, 173). The Si II 635.5-nm absorption line is blueshifted with respect to the galaxy (NGC 3021, recession velocity 1500 km/s) by 14~000 km/s and has a FWHM of 6900 km/s." An updated e-chart follows, replacing that on E1014. \\\\\\SN 1995al c in NGC 3021 S,400,5,S -C, 9.8500, 33.5500,2000 O,186,199,13.2,? -L,L,SN P,09h 50.9m +33 33' (2000) -T,Seq GSC -G,193,197,120,60,90 -L,R,N3021 -S,SN/029.01 M,8,52,163 -L,L,78 M,10,343,29 M,11,249,20 R,10.1,151,229,A R,10.9,204,205,B,A R,11.98,280,232,C R,13.0,264,200,D R,13.5,240,178,E R,14.1,197,194,F,B M,12,5,3,351,15,366,40,158,90,25,78,52,77,330,292 M,13,360,16,187,25,299,142,39,132,290,127 M,13,300,48,125,372,347,357,24,354,256,329,291,291 M,14,37,205,121,2,74,186,333,178,239,19,159,152 M,14,183,33,235,34,227,124,320,119,341,45,331,47,334,345 M,14,46,337,190,272,378,271,255,244,246,245,27,239,16,234 M,15,276,194,80,182,317,8,41,9,84,22,335,23,359,161 M,15,198,39,93,42,123,117,268,101,148,54,337,83,49,383 M,15,241,378,230,340,41,338,259,325,337,307,356,307,51,269 M,15,59,267,241,240,225,232,107,225,292,223 M,16,24,200,96,189,326,54 E,77 ////// Basic chart automatically generated by CHART ver Guy M Hurst
