One more week of the exhibition at Mikaels church in Ryd, Linköping
The vernissage had a lot of spectators because it was held after the service in
the church. I gave a short talk at the church coffee. Some students from other
counties were very interested to the old school of Sweden.
In the coffee room at Mikaels church
The news paper of the town, Corren, had an article about me and the exhibition.
The article can be read in Swedish here.
The local TV station, TV4, asked for recording of a reportage about the exhibition and a
visit to my old school, Vasaskolan. A young reporter and photographer, Hanna Kastner,
came and did a one and a half hour long recording. She was very skilled and did a
wonderful work. My wife took some photo of the interview.

The life of an oriental poppy
Poppy pollen spead in the wind
I have been following the short life of a single Oriental poppy (Papaver orientale) in our garden.
Photos from the opening of the bud to the drop of the petals could be seen
here.
The transport of the pollen by
the wind was recorded in the image above(magnified).
The speed of the pollen grains could be estimated, from the length of white lines and aperture speed, to be around 2 m/s.
Bumble bees transported the pollens away to the other flowers.
A rain- and hail storm beats the petals
Heavy rain and hail storms battered the flower
several times and finally end the beauty of the poppy. Next year we will place the seeds of this poppy in the soil to get a new beautiful poppy.

Sun Halo seen in Lund, Sweden at 12:45
Sun Halo at Lund in Sweden. Time 12:45
A Sun halo can occur when the sun shine through high clouds like cirrostratus nebulosus. High clouds
can contain hexagonal ice crystals and when light refracts through these crystals a ring around the sun is
generated. In the halo mainly refraction occur, contrary to the rainbow, which include both refraction and
reflection phenomena.
The Sun halo exists only if the ice crystals are of the right size and geometry. Because the temperature
falls with about 6 C per kilometer up in the air the summer cloud must be at about 6 km the give the right
size, 0.05 mm to 0.5 mm, of small crystals. This is the right size to generate a fall down with the hexagonal
face down wards. When the crystals fall in this way the light will refract at a constant angle and the halo
will occur around the sun.
The spectrum around the sun is usually difficult to see clearly, but in the halo the red color is on the
inside of the halo and the blue color is on the outside (see the image below). This is the opposite to
the color spectra of the Rain bow as can also be seen in the image below.

Wild life at Lat N 59o 48' 26" Lon E 15o 32' 56".
Green Hairstreak (Callophrys rubi)
Early summer life in the 2000 square meter of Tallsigen 5 in Riddarhyttan includes not only grandchildren's play,
but also the start of the summer wild life season. The pair of Pied Flycatcher (Ficedula hypoleuca) is working hard
to soften the bed for the eggs. The family of the Great tit (Parus major) already has eggs under the newly repaired
roof top of the old pig shed of the soon hundred years old home. The Eurasian red squirrel (Sciurus vulgaris) is
fantastic to balance on the fence on his way for more food in the nearby forest. Our permanent inhabitant, the
Robin (Erithacus rubecula), has a nest in one of our Norway Spruce (Picea abies) trees and works hard in the wind
to get food for the family.
In the wild garden there are plenty of Bilberry (Vaccinium myrtillus) plants in full bloom. Our resident,
they live under roof of the house, bumblebees (Bombus) fly around with heavy yellow legs to collect nectar from
all the Bilberry flowers. The butterflies start fly around on looking for the flowers. For the first time I used
a long telephoto lens 300 mm and a 2x-extender to photograph the insects. One of the butterflies was the almost
white Green-veined White (Pieris napi), very beautiful from the side and showing a strange structure in the eyes.
One of the more spectacular butterflies in the garden is a green blue, about 1 cm small, which could be identified as the
Green Hairstreak (Callophrys rubi). It lives among bilberries until the month of June.
Please take a look at the photos here.
