    The bottom part of a towel with a Hertzsprung-Russell diagram printed on it

    Our puzzler prize for this year (well, its lower part): The Hertzsprung-Russell diagram according to Gaia on a wonderfully soft towel.

    After two years of “virtual” meetings, this year the venerable “Herbsttagung der Astronomischen Gesellschaft“, the meeting of Germany's Astronomical Society, is back. Almost as before Corona, it is bringing astronomers together, this year in Bremen (previously on this blog: 2018 in Stuttgart).

    Bowing to the “German“ in GAVO, this is an opportunity for us to connect to the (or, rather, our) community, both with a splinter meeting and with our traditional booth, at which you can pick up various edifying printed matter, a laminated ADQL reference card, and lots of VO wisdom (i.e., chat with our friendly booth staff).

    And you can solve our puzzler, a little problem that has an elegant VO-based solution (previous puzzlers). As is tradition, solving the puzzler will not only give you intellectual satisfaction and perhaps even insights into the VO, it will also give you a chance to win an item that is heavenly fluffy. The article photo shows this year's puzzler prize, and if this piques your desire, absolutely feel free to hand in solutions even if you are not in Bremen[1].

    Update 2022-09-15: This year's prize went to Bonn. So, there's no point to hand in solutions any more – rather, have a look at how we thought the problem should be approached.

    [1]We've had an actual award (the AG-RAS Carolin Herschel medal) being handed out virtually yesterday, so in case we really draw a remote entry, I am very confident that we can work something out for handing over the prize.

    towel with astro photo

    Our puzzler prize this year: a Photo of the seahorse in the LMC, taken during Hubble's 100000th orbit around the earth, on a fluffy towel.

    It's time again for the meeting of the Astronomische Gesellschaft (as 2017 in Göttingen; last year we had the IAU general assembly instead). We're there with a booth (right next to the exhibition on 100 years of IAU) and a splinter meeting, at which I'll have a sales pitch for cross-server uploads.

    And, of course, there's a puzzler again: you could win a beautiful towel if you solve a little VO-related problem. This year's puzzler is about where in the sky you'll see “nebulae” (in the classic sense defined by NGC) batched together most closely. If you've been following this blog for a while, it shouldn't be too hard, but to participate you'd have to find someone in Stuttgart to hand in your solution.

    If you are in Stuttgart: As usual, we'll be giving hints during the coffee breaks on Tuesday and Wednesday. So, be sure to visit our booth.

    Photo of our booth

    For the 11th time, GAVO has a booth at a meeting of the venerable Astronomische Gesellschaft (AG). This year, we are in Göttingen, again offering advice to users and data providers at our booth (if you're looking for us: We're close to the entrance of Hörsaal 5).

    And again we have a Puzzler, a little problem easily solved if you know your VO tech – and if you don't we'll gladly help you at our booth. We are also giving hints there, one being released at each coffee break on Tuesday and Wednesday (there are little posters with them, too, if you miss one). Of course, if you're not in Göttingen, you're still welcome to try your hand. You won't get to win our great first prize then, the big Crab Nebula towel (it should be easy to spot on the image above).

    If, on the other hand, you are in Göttingen, be sure to drop by our splinter meeting. Yours truly, for instance, will speak about EPN-TAP (remember And the Solar System, too right here? That's what this is about).

    Update 2017-09-20, 17:00 We've just given out the last hint for the puzzler, and so we can publish them all over on the puzzler archive: Hints for the 2017 puzzler. If you're in Göttingen, you still have until tomorrow 16:00 to hand in a solution and perhaps win our nice and fuzzy Crab Nebula towel.

    Update 2017-09-21, 17:00 And the winner is... again not from Marburg, which is beginning to become a running gag, and they've been unlucky for the last three years in a row. Anyway, here's our proposed solution.
