All things astronomy and space (and then some) - in tiny bits and pieces but mostly with links to more ... :-)

Beginner's luck, but also frustrating: on the very first test picture a bright Perseid flew thru the field of view tonight, but it only left a feeble track, despite ISO 1600 and f/2.8: the wide-angle (25 mm equivalent; cropped here) apparently didn't allow the - fast, thru the zenith! - meteor to register much. Gotta think a bit more about better settings for tomorrow ...

Thank you, #MSL, for bringing all those visitors to http://skyweek.wordpress.com which was Mars-only for the past 5 days with three subsequent live-blogs. And please deliver more excitement next week after the software change!

Unusually - I think - complicated sundog this evening, here in a contrast-enhanced version. Before I could rush for the camera the feature (to the right of the Sun) was even brighter - and very narrow and sharply defined. Probably cloud edges playing a role.

Here is the proof - the fairing separation images shown during Ariane 5 launch webcasts ARE NOT LIVE! This is the view broadcast a few minutes ago - and http://twitpic.com/9lheto shows a screencap from a launch on 16 May: clouds and lighting are identical. Arianespace, this is not right!

Unusually clear view of booster separation during the ongoing daytime Ariane 5 launch.

Just seen on live TV: NASA has caught a (somewhat small) Flying Saucer and shown it at a press conference! (It's a scale model the Mars Science Laboratory in its aeroshell, of course. :-)

Here's another decent flash picture I just took - settings were ISO 100, 30 sec with f/5.0 and maximum wide angle, then cropping the good stuff. More at http://www.facebook.com/media/set/?set=a.3790220908971.2139769.1080556720&type=1&l=22393a7aed

While the #olympicceremony in London was approaching its climax, so did a thunderstorm over Bochum, Germany - got some nice flashes, more in http://www.facebook.com/media/set/?set=a.3790220908971.2139769.1080556720&type=1&l=22393a7aed

Missing in action: the beloved failwhale! Instead during today's Twitter outage we got this semi-message ...

A rare glimpse of actual science data, from a webcast talk by Sam Ting at CERN today: the instrument - sitting on the ISS one year now - is seeing the periodic system of elements in the cosmic rays it catches. Again no hints dropped on when detailled and potentially new science will be released.

More live music photography on the weekend: "The Voice" in Landsberg and - seen here - "Still Collins" in Bonn, Germany: lots more photographs in http://www.facebook.com/media/set/?set=a.3707691845796.2138033.1080556720&type=1&l=d272dcbb15

Fascinating ... an old friend of fine, Moh'd Odeh - who was our host in 1999 at the Jordanian Leonids camp & conference http://www.astro.uni-bonn.de/~dfischer/leo99/story.html - in a looong Arabic TV talk show http://www.youtube.com/watch?v=0QWoX0eqXzc discussing the Ramadan lunar sighting problem. I know only a few words, but "hilal" (crescent) comes up pretty often.

30 years ago today, on 20 July 1982, I went on my first solar eclipse 'expedition' - to a little hill south of Bonn, Germany, but that added elevation was crucial: it lifted me a tiny bit above a dense haze layer so I could spot a few minutes of early partiality while folks down in Bonn saw nothing at all. Here's my report, published in Telescopium Vol. 10, 46 (4/1982), with drawings made from color slides.

Here goes the Soyuz! And within a few seconds the rocket was already out of sight, disappearing behind clouds.

The #ICHEP2012 summary slide from LHC CMS, which sees a narrow resonance at 125.3 +/- 0.4 (stat.) +/- 0.5 (syst.) GeV - and these error bars are conservative and will be smaller when the ATLAS & CMS papers will be submitted on 31 July.

And now the #ICHEP2012 CMS talk on that ~125 GeV LHC resonance - the results from both main detectors are nearly identical, something that was not guaranteed at this time.
