    Hello folks,

    Isn't Stellarium supposed to show moon eclipses? I set it to the time/date
    provided
    here
    for my location (Rio de Janeiro, Brazil, ie, zone P1: 08:48:09 UT ==> 05:48:09
    local time), but it just showed a standard full moon.

    I then set the time back 1h, centered the display at the moon, and let the
    time advance until ~15 mins after the above time: the moon showed as full
    (without any eclipse "bite") for the whole period.

    That was originally with Stellarium 0.11.0; I've since downloaded the source
    code for 0.11.3, compiled and installed it myself, and then repeated the test
    with the exact same results.

    What's wrong here?

    Thanks in advance,

    Durval Menezes.

    Hi Durval

    Have you got the correct time. It is happening now as I write this. The GMT
    time is 10.35. It shows very well on my computer with the moons umbral shadow
    covering almost half the moon. However the darkening for the penumbra is only
    just noticeable.

    Do you have the moon display at 4 times enabled, make sure it is disabled.

    Hi Durval - unfortunately in your location the entire eclipse happened below
    the SW horizon after moonset. If you want to see that in Stellarium, turn off
    the ground (G), then go to time 2012-06-04T04:00:00, find the moon, zoom in,
    then speed up the time.

    Barry, Boinka,

    Thanks for the responses. In fact, I spent the early morning watching the moon
    for the eclipse and it happened just like Stellarium showed, ie, no "bite"
    until it disappeared below the horizon.

    Barry, indeed at GMT 10:35 it shows alright in Stellarium here; from what I
    can determine watching the simulation, Moon started entering the umbra at
    ~10:04GMT.

    So, what gives? Was the original PDF I linked (to wit: http://www.nightskyinf
    o.com/sky_highlights/june_4_2012/june_4_2012.pdf
    ) just plain wrong? Or have I
    misinterpreted it somehow?

    Thanks again,

    Durval.
