Jupiter on 1960 June 12/13 at 23:00-23:10 EDT (03:00-03:10 UT) as sketched by K.R. Brasch. C.M.(1) 284º, C.M.(2) 327º. 8" reflector at 165x. Seeing 2-3. Transparency 3.

Red spot seen, a gray washed out colour similar to S.P. region. Easier seen with the aid of a light blue filter, as outline of spot is more distinct. Shadow + disk of satellite I seen, shadow left disk at 03:19, disk of satellite at 03:29.

Jupiter on 1960 June 11 at 02:55-03:08 EDT (06:55-07:08 UT) as sketched by K.R. Brasch. C.M.(1) 112º, C.M.(2) 168º. 8" reflector at 165x. Seeing 3-4. Transparency 2-3. S.I. of shadow of satellite I at beginning of observation—1:37 EST. T.I. of satellite begun at 1:50 EST, disk easily visible, brighter than surrounding zone N.T.Z. of main planet.

Jupiter on 1960 June 10/11 at 01:57+25m EST (06:57 UT) as sketched by Jim Low. C.M.(1) 110º, C.M.(2) 166º. 4" reflector at 130x, 167x. Seeing 6. Transparency 4. North is down. The dark cond. (left dark marking) was not as dark as the shadow of satellite I (right dark marking).
