En la web de las próximas aproximaciones de NEOs, ha aparecido este cometa. Se acercará a casi 8MM de Km. de la Tierra y si no me equivoco lo podremos observar (desde España) al principio de la noche de los días 28 y 29 de Mayo (justo antes y después de la máx. aproximación que será sobre las 10:10 UT del día 29).
