    Default Visibility of Smart-1 impact



    Here's a site with an analysis of the visibility of the Smart-1 impact:

    http://slrea-smart1lunar-impact-proj....blogspot.com/

    In short, the impact itself (mag 17) will not be visual for small scopes.
    There is a low probability that it will create a dust plume that might
    reach up into the sunlight, resulting in illumination of the cloud to a mag
    11 brightness. Mag 11 can be reached by most small scopes.

    In short, not alot to get worked up about, but worth a peak.

    Photographic (CCD or web cam taking images at 30 sec intervals) seems the
    better way to go.

    Here in the UK the BBc are showing a graphic with an ~1/6 lunar radius
    cloud ~1/8 lunar radius high looking around mag 8 :-)
    Several calls "...will it be visible with naked eye/bins/etc" from
    local radio stations.

    either. -

    That's the dust ejecta from a crater about _1 to 5 meters_ deep - which
    is not alot of volume - spreadout over a 100-120km horizontal radius.
    That will not be visual because it will be hidden in the dark limb. It
    will be visual depending on how much of that ejecta cloud goes
    vertical and peeks above the dark limb into the sunlight. How much of
    that will occur, I don't know. But it's certainly worth a 5 minute
    peak with binos or a scope, with the expectation that you probably
    won't see anything.

    So long to Smart-1. It's been a great satellite. Looking forward to
    the ESA processing and releasing all the photos.

    I hope Venus Express, which I understand has just completed its orbit
    breaking manevuers, will be as successful.

    By the way, I was wondering you British were scheduling any web casts
    on the impact that we could tap into. I believe you have a great
    system of 2 meter educational scopes spread around the world. Heard of
    any?
