Comets C/2011 W3, C/1970 K1, C/1965 S1, and C/1843 D1 in a plot of the longitude of the ascending node against the orbit inclination for 1565 SOHO Kreutz sungrazers from the period 1996 January to 2010 June. C/2011 W3 is identified by the square, C/1970 K1 by the spade suit mark, C/1965 S1 by the filled circle, while the location of C/1843 D1 coincides with the dense concentration of the SOHO sungrazers and is in the center of the open oversized circle. Comet C/2011 W3 appears to be orbitally related to a cluster of up to nearly 30 SOHO sungrazers, with the ascending nodes between 310° and 335° and with the inclinations between 130° and 137°.
