429. Out of focus

I tried this latte on going by bicycle. It was pretty tasty.
So, I took a shot by putting it on the saddle of my bicycle. Though the focus is at the street side, it shouldn't matter much.

428. Oo-jisibari / butana

The weed at a nearby square was cut out just recently, yet they came back again as in the photo.
=2020-05-25 mon sharp aquos sh-o1l=
It looks like the yellow flowers
are called oo-jisibari*.
Becasuse of this tough nature, they can occupy this place year after year.
*After-note: Checked the entire appearance of the yellow flowers in the above photo on the walk this morning, as in the left photo.
=2020-05-27 wed sharp aquos sh-o1l=
It has leaves like dandelion, and stems with branches. This looks to indicate that it is
butana and not
oo-jisibari.
427. Kaki
Kaki (persimmon) at my place blossomed.
Every year I cut out its branches and seldome saw the flowers. Last year I refrained from pruning the tree. Then the result is this.

426. Siran
=2020-05-22 fri sharp aquos sh-o1l=
A long spell of rainy days has kept
siran at my place drenched.
I remembered the right one in a pot had just the same name,
siran (purple-orchid). Then it means "white purple-orchid". Without realizing, I murmured
"dottti-ya" in Kansai word ("which one").
Checking online revealed that it is generally called,
"siro-bana siran" (white flower purple-orchid).
425. Aspect ratio of 250
Hera-oobako is everywhere at this time of year. This is the one taken at the entrance of a nearby water supply faciltiy.
As in the photo, it employs an inflorescence like an observatory atop a slender stem. It looks mechanically disastrous, yet seems all right.
=2020-05-19 tue sharp aquos sh-o1l=

I took a stem and measured its length and diameter.
Length 65 cm, Dia. 2.6 mm. The ratio of length to width, aspect ratio, is 650/2.6 = 250.
=2020-05-19 tue canon ixy digi55 es ps sx40hs=
For example, in case of Tokyo Skytree, the height is 634 m, the lower section is said to be an equilateral triangle with a 68-m side. Thus its aspect ratio is 634/68 = 9.3.
In an extreme case, an elcetric distribution pole comes. This is roughly, dia. 30 cm and length 10 m. The aspect ration is 10/0.3 = 33.
As I thought, the aspect ratio of 250 is extraordinary. If this is applied to an antenna design, by utilizing a 40 mm dia. pipe, it is possible to install a self-standing antenna of 250 times the diameter, i.e., 10-m high antenna. Those who oerate radio must be jealous of such design.

The stem looks to consist of a bundle of a number of fibers.
The photo shows a look of the stem through a 10x loupe. The stem is composed of 6 fibers by bundling them together, straight without twisting.
=2020-05-19 tue canon digi55=
After all, it employs a trick in its own way.
424. A zari-gani

A
zari-gani we encountered at the morning walk a few days ago.
Jiro seemed not so much interested in it, as if only saying "what's this guy".
=2020-05-15 fri sharp aquos sh-o1l=

It was a sidewalk of a street facing paddy fields at one side and a large stormwater reservior at the other. The street is 10 m above the paddy fields.
=2020-05-18 screenshot / national geospatial information authority=
The map of National Geospatial Information Agency shows the elevations of the paddy fields 7 m, the road 16 m, and the reservior 9 m. I put the figures into the map.
Those like
zari-gani or turtle look to know the existance of water basin on the other side of the embankment, and go and return between them.
423. Suiren
=2020-05-17 sun canon ps sx40hs=
Suiren in full bloom. Large flower about the size of opening a hand. At the moat of the castle site park.
422. Sporadic E layer

There appeared a strong sporadic E layer. NICT ionogram of last evening.

421. Summer has come in

Suddenly summer has come.
A
yuri-no-ki (tulip tree) at a nearby square this morning.
Though its flowers must have been blossoming by now, it is difficult to see them clearly.

420. Deities of a clan going across the sea

Just got a rare book. This shows its cover page.
A manga about the clan related to the Munakata Great Shrine, designated as a world heritage, centering on the times when Yamato sovereignty was being established in the Nara basin
#1.
=2020-05-04 mon canon ixy digi55=
As widely known, this clan had been actively engaged in trade throughout the country, based in the Genkai Sea, since long before the ancient times. There exists a Munakata shrine close to my place too. In some regions, several different Chinese characters are adopted to express the same "Mumakata" word.
It is well known that they had tattoos on their chests or shoulders, probably to identify themselves as seafarers, with stringed triangle images, possibly suggesting fish scales. This practice is also said to be the origin of the name "Muna-kata",
mune (chest) and
kata (shoulder).
Nationwide, there exist 69 shrines with that name of "Munakata". Of which 13 are, for some reason or other, at a narrow strip on the upland in the west of the Inba Marsh, that is an academically interesting subject
#2.
The area corresponds to the current Chiba New Town. In fact the area is full of the districts with the names including characters of ship and
to, olden word of port, despite the fact that they are all on the hills. Also there is a district with the name, just "Munakata". This suggests that the area had been a bridgehead of the clan in the east.

This is one of the 13 shrines located at Moroto, Inzai.
=2020-05-03 sun canon ps sx40hs=
The notion being the deities of a clan who crosses the sea is tremendously different, in its scale of image, from those of the deities of scholarships or businesses.
Munakata Shikou, a printer and a parishioner of Utou Shrine in Aomori which enshrines the same deities as "Munakata", is said to have been proud of himself being a member of the "Munakata" clan throughout his life. I know the feeling.
