Venus on 1961 April 21 at 12:00-12:10 local time (17:05 UT) as sketched by G. Gaherty, Jr. 6" refractor at 150x. Seeing 1-2/10. Transparency 3-4 (daylight). Cusps definitely extended more than 180º, shadings probably contrast effects. Ashen Light suspected. Phase 4% –K.B.
Venus on 1961 April 9 at 05:05 + 11m EST (10:05 UT) as sketched by Jim Low. 4" reflector at 130x. Seeing 2. Transparency 3. This is an unusual observation. Venus was still east of the sun (an "evening star"), but was visible in the morning before sunrise. This is because it was well north of the sun in declination. Venus was only 9º from the sun. This observation was made 38 hours before inferior conjunction.
Venus on 1961 April 9 at 11:00-11:10 local time (16:05 UT) as sketched by G. Gaherty. 8" reflector at 90x. Seeing 2. Transparency 4-5. Illuminated atmosphere as hair-line all around disk. k = 1.5 (27 hours from inferior conjunction).
Venus on 1961 March 25 at 13:50-13:55 local time (18:55 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 1-2/10. Transparency 3-4/5 (daylight). No detail other than terminator shading; ashen light vaguely suspected.
Venus on 1961 March 25 at 13:35 EST (18:35 UT) as sketched by G. Wedge. 6" refractor at 150x. Seeing 4/10. Transparency 2/5. Daylight observation, faint suggestion of ashen light within dotted line. Detail slightly exaggerated.
Venus on 1961 March 19 at 17:15-17:25 local time (22:15-22:25 UT) as sketched by K.R. Brasch. 8" reflector at 165x-375x. Seeing 4-5/10. Transparency 3-4/5. Detail very definite. Area along limb brilliant. Central area (7.5) darkest + terminator uniformly dark.
Venus on 1961 March 12 at 17:15-17:45 local time (22:15-22:45 UT) as sketched by K.R. Brasch. 8" reflector at 165x-300x. Seeing 4-5/10. Transparency 3 (daylight). Detail relatively conspicuous, North P. region quite dark, Ashen light suspected along dotted region. Band structure quite definite with filter.
