S. Howell, Arecibo Observatory and A.J. Lovell, Agnes Scott College, report on IAUC 9191 that observations at the Arecibo Observatory obtained on six nights between 2010 Dec. 14 and 2011 Jan. 4 show no clear detection of the 1667-MHz line of OH in the coma of (596), currently in outburst. The 3-sigma upper limit of the line strength is 0.90 mJy km/s, which corresponds to production rates of log Q(OH) = 26.31 (Despois et al. 1981, A.Ap. 99, 320) or log Q(OH) = 26.30 (Schleicher and A'Hearn 1988, Ap.J. 331, 1058). SATURN XXVIII (ERRIAPUS) Regarding the naming of Saturn XXVIII, J. Blue, U.S. Geological Survey, writes that the Working Group for Planetary System Nomenclature voted some time ago to change the spelling of "Erriapo" to "Erriapus". (IAUC 9191).
