In the period from May 31 to June 7, 2013 I
was on the Dutch island of Texel for a short vacation with my wife Lizzie and our
three dogs. We
stayed in a cottage a few miles southeast of De Cocksdorp, the uppermost northern
village on Texel. Last
year we were here also and I then noticed that the 100 meter deep backyard was
very dark. At
the front of the house stands some lonely lampposts that were shielded through
the house as seen from the dark garden. The
north side has a view to the horizon. A
lighthouse at a distance of 5 km (northwest) gave some some
inconvenience. The light beams lit up the trees a
bit every 10 seconds. But it was not really a
problem for observing because I looked to the southeast and the lighthouse was
also behind a row of trees.
the weather was not good in 2012 (every night it was cloudy), but this year it
was much better! Especially
during the day it was often pretty clear. I had 4 mostly clear nights and I
used two nights to observe meteors and satellites and took some pictures of the

beautifully clear evening, but on the North Sea some clouds were lurking. After
21:15 UT I regularly went out to see if there were some noctilucent clouds (NLC's).
They were not present at that time. When
I walked into the garden again around 22:15 I was surprised by the sheer
transparency and darkness of the sky (despite the gray nights). Around
23:30 UT the sky was phenomenal: the Milky Way was visible from Cassiopeia to
just above Sagittarius! Under
the well-known "star cloud" of Scutum two clear spots were observed
in the Milkyway. I have rarely seen
them so beautiful from the Netherlands!

I started observing meteors I took some pictures with my Canon EOS 40D and I
wondered about the fact there already was so much to see in the display of the
used my Canon EF 35mm F1.4 and Canon EF 15mm F2.8 lenses. Halfway
through the meteor session I took a short break to get the ISS on the plate Because
of the dark sky I could obtain a beautiful serie of photographs from the ISS
while it moved through the Milky way.
number of meteors was low as expected for this time of year. I counted 15
meteors in 112 minutes effectively, including a beautiful magnitude 0 earthgrazer
with a four seconds lasting persistent train.

I saw visually no NLC's this night, but on
a number of shots taken with the Canon EF 15 mm clearly some weak NLC’s are

Also this night
was largely clear. Unfortunately
there was quite a cold wind and the air was very moist. Between
22:30 and 23:55 UT I observed 6 meteors. The canon EOS 40 with the Canon EF 15 mm 2.8 fish eye lens
captured two meteors within 5 minutes time. A bright magnitude -2 sporadic meteor in the Scutum star cloud and a second one of magnitude +1 or 0 in the constellation of Aquila. The last one I saw visually. I made a nice composition of it.
Picture 8: two meteors captured within 5 minutes. Date: june 5, 2013 around 22:40 UT. Camera: Canon EOS 40D with Canon EF 15 mm F 2.8 (F 2.8, 1600 iso, exp. time 10 s). Click on the image for a larger version.
addition, I could observe the two hours earlier launched ATV-4 Albert Einstein,
including a predecessor moving some degrees before the ATV-4 spacecraft.
According to veteran satellite observer Marco Langbroek it was the upper stage
of the Ariane-5 rocket that brought the ATV-4 up! The ATV4 was
magnitude +1, the upper stage was magnitude +3. They moved
along quite quickly because they were still in a low Earth orbit. It was a beautiful sight! This
combination is also captured with the Canon EF 15 mm F2.8, but unfortunately
the lens was slightly dewy. Below you find some pictures I made of ATV-4. I had to edit the images extremely to get ATV-4 and the Ariane 5 upper stage visible.
also saw the ISS this night, it moved very high through the sky and was as
brights as Venus (magnitude -4). I ended my observations at 23:55
UT because it became cloudy..
all two very nice observing sessions. The
starry sky above Texel is (according to Dutch standards) very beautiful!

A dutch written report from Namibia, with many pictures! Pictures of astronomical objects will also appear on my blog, but that will take some more time.... Click on the image above for a report.
