[Sagamihara-shi Kanagawa-prefecture Japan]
≪神奈川県相模原市 佐藤康明≫
Venus captured during several minutes improved seeing period today,could get only 2 set of IR685,UV and CH4.
Very poor seeing except this timing due to high altitude jet stream..
≪東京都 立川市 皆川伸也≫[Nobuya Minagawa:Tokyo Japan]
Under good images. Conspicious polar caps bordered by a dark collar were noted,
a thin banding pattern was noted,AL was not there,bright spot as well.

Seeing 8/10 Transparency 8/10
[Szabolcs Nagy: London United Kingdom]
I had some really good seeing here and I was afforded some of my best views of Venus I've had in a very long time,
with the planet perfectly steady in the eyepiece. Quite remarkable given how clear and transparent the sky was!
- Illuminated Disk: Some subtle markings,patch like cloud structures seemed to be present.
- Bright Limb Band: Visible and complete
- Terminator: Geometrically regular
- Cusp Caps: Both very brilliant tonight but perhaps the northern cusp was slightly brighter.
- Cusp Collars: Both present- about equal.
Concluded observations at 1919UT as it was by then,too dark to observe the planet.

[Silvia Kowollik Ludwigsburg,Germany]
≪茨城県 : 阿久津富夫≫
North is up in all images; observation with apodising screen.
Faint banding was suspected with the W47 (violet) filter. The W12 (yellow) filter showed an incomplete bright limb band and a single bright cloud near the southern limb. Cusp caps were seen with both filters as terminator shading.
