Lipkin\n(Wise observatory, TAU) report:\n\nWe searched the list of IPN error-boxes derived for GRBs detected \nbetween September 15 and October 28 2003,\nfor a spatial coincidence with SN 2003jd (Burket, Swift and Li, 2003; IAUC\n8232), which is spectroscopically similar to SNe 1998bw and 2003dh,\nassociated with GRBs 980425 and 030329, respectively \n(Filippenko, Foley, and Swift 2003, IAUC 8234;\nMatheson et al. 2003, IAUC 8234, GCN 2431).\n\nWe find that the position of SN 2003jd falls within the 3-sigma preliminary\nerror annulus of the short/hard GRB 030929 (Hurley et al. 2003; GCN 2409)\ndetected by Konus-Wind and INTEGRAL (SPI-ACS).\n\nSince the total area of IPN 3-sigma error-boxes and annuli derived \nbetween Sep. 15 and Oct. 28 2003 covers 5.6% of the entire sky,\nand the reported error annulus is preliminary, this coincidence\nmay well be by mere chance. We also note that GRB 030929 is a \nshort, hard burst, while previous events associated with SN 1998bw-like SNe Ic \nwere of the long, soft variety. Additionally, if SN 2003jd is associated\nwith GRB 030929, the SN rise time (~30 days) is somewhat longer\nthan observed in previous cases (e.g., ~17 days, for SN 1998bw).\n\nFurther inspection of the relevant IPN data may shed more light on\nthis possible association.",
