     Why not try your hand at observing an exoplanet transit in support of the ARIEL Space Mission? All the information you need can be found at https://britastro.org/sites/default/files/ARIEL%20Space%20Mission%20V2_0.pdf. More details on the ARIEL ExoCLock project can be found at https://britastro.org/node/20102 We will be pleased to show your results at the Exoplanet Division meeting on the Saturday afternoon of this year’s BAA Winchester Weekend.

    I would like to echo Roger’s message by encouraging would-be observers to go to the website and register your observatory as a future participant mentioning in the ‘Comments’ box that you are an amateur astronomer and that you are joining the BAA Exoplanet Division’s initiative to support the ExoClock Project.

    We just need some clear skies now – Haven’t seen a properly clear night since last November!

    “go to the website and register your observatory as a future participant mentioning in the ‘Comments’ box that you are an amateur astronomer and that you are joining the BAA Exoplanet Division’s initiative to support the ExoClock Project.”

    Been there, done that.

    Clear skies are erratic in these parts.  It was (mostly) clear last night but with ferociously high katabatic winds so no observing was done. In those conditions the seeing is typically 15-20 arcsec and the scope flaps around on a similar scale, ruining tracking, even though it is inside a dome.

    Have done a couple of observations now and uploaded to ExoClock. The HOPS software is good and relatively simple to use, but I’ve discovered a slight flaw: If you choose a comparison star that is saturated, the software crashes. Have been in touch with the developers and this will almost certainly get resolved.

    Obviously there’s no point in choosing a saturated star but if you do it by mistake (as I did) it crashes. There’s no facility to check the levels of the stars you selected yet so I used the AstroImageJ seeing profile tool. Hopefully something will get added to HOPS to avoid mistakes in future.

    Sounds like I’m not the only one with installation issues.

    When installing HOPS if you get an error: “The ordinal 242 could not be found in the dynamic link library” try the following:

    It’s not a HOPS problem as such but an Anaconda one.

    In the Windows/system32 directory find a file: libiomp5md.dll

    Try renaming it to libiomp5md.dll.bak

    I believe it is a file installed by other software which conflicts with Anaconda (not HOPS). Sorted it for me. Hope it does for you too.
