Venus on 1961 January 21 at 13:10-13:20 local time (18:15 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 1. Transparency 3. Almost at dichotomy.

Venus on 1961 January 5/6 at 16:55-17:05 local time (22:00 UT) as sketched by Geoffrey Gaherty, Jr. 8" Cave reflector at 180x. Seeing 3. Transparency 2-1. Transparency deteriorated at end of drawing making intensity estimates impossible.

Venus on 1960 December 24 at 12:48-12:57 local time (17:52 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 3-1. Transparency 4 (daylight). First attempt at intensity estimates of Venus; of doubtful value.

Venus on 1960 December 17 at 14:00 EST (19:00 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 1-2. Transparency 3.

Venus on 1960 December 3 at 13:35-13:42 local time (18:38 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 3. Transparency 3 (daylight). Markings very difficult. Fairly certain of cusp bands; diagonal streak less certain.

Venus on 1960 November 19 at 14:50-15:00 local time (19:50-20:00 UT) as sketched by G. Gaherty. 6" refractor at 150x. Seeing 1. Transparency 2.

Venus on 1960 October 12 at 15:25-15:35 local time (19:25-19:35 UT) as sketched by G. Gaherty, Jr. 6" refractor at 150x.  Seeing 1-2 (image boiling). Transparency 4 (daylight observation). Planet appears yellow-green against blue sky. Markings very indefinite.

Venus on 1960 October 10 at 16:00-16:05 local time (20:00-20:05 UT) as sketched by G. Gaherty, Jr. 6" refractor at 150x. Seeing 1. Transparency 3. Daylight observation. Planet appeared green against blue sky background. Markings drawn, except terminator shading, were extremely indefinite and of doubtful reality.

Mars on 1961 January 4/5 at 23:05-23:15 local time (04:10 UT) as sketched by Geoffrey Gaherty Jr. C.M. 284°. 6" refractor at 220x. Seeing 5(!)/10. Transparency 4/5. T = 1°.

Mars on 1961 January 11/12 at 23:05-23:15 local time (04:10 UT) as sketched by G. Gaherty, Jr. C.M. 222°. 6" refractor at 150x. Seeing 3-0. Transparency 4. Drawing terminated due to poor seeing. T = 0°.
