Venus on 1961 June 3 at 13:50-13:55 local time (17:55 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 1-2/10. Transparency 4-5/5. Phase estimated as about 42%. Seeing too poor to permit intensity estimates.
Venus on 1961 May 14 at 14:05-14:15 local time (18:05-18:15 UT) as sketched by G. Wedge. 6" refractor at 150x. Seeing 2-1/10. Transparency 1/5. Two notches near northern cusp very indefinite, other markings except dusky mark just south of centre very indefinite. Intensity estimated from drawing and from memory.
Venus on 1961 May 11 at 11:15-11:25 local time (15:20 UT) as sketched by Geoffrey Gaherty, Jr. 8" reflector at 180x. Seeing 1-2. Transparency 4. Daylight observation. Ashen light suspected. Terminator looks reddish brown, rest of planet white.
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).
