S. Ortolani, Feltre, Italy, has independently reported the discovery (cf. IAUC 2812) of a disturbance in Jupiter's South Equatorial Belt at longitude 207o.4 (System II) or 253o.8 (System I). The observation was made on Aug. 6 with a 30-cm reflector (250 x); use of a filter showed that the feature was blue in color. Another cablegram from the Agrupacion Astronomica, Sabadell, Spain, reports that on Aug. 12/13 M. Cortes observed a disturbance at longitude 120o (System II), the first time that three disturbances in the South Equatorial Belt had been under observation simultaneously. On Aug. 16/17 Gomez and Reginaldo measured the center of the dark column of this disturbance at longitude 119o.0.
