Is this really the 21 mag asteroid (427377) 2014 XF15 ?

    Hi,
    this seems to be the 21 mag asteroid (427377) 2014 XF15. The trajectory fits perfect but it seems to be brigther in the picture, doesn't it?

    Regards,

    OK, it could be also (41373) 2000 AR101 which has mag 19.5.

    Which Observatory code fits best to the images here?

    (41373) 2000 AR101, M:19.4
    (427377) 2014 XF15, M:21.0

    Star-bleeds seriously limit the maximum magnitude of objects that are still visible/detectable. Also M:21.0 objects are, as far as I know, out of range even in good quality conditions. (Magnitude is a logarithmic-scale)

    So (427377) is out for sure. That leaves (41373), ... or a new/unknown asteroid of course. 😉

    But this makes its a pretty sure case its the (41373) asteroid.

    Nice spotting job btw. 😃

    (General additional note: These known-asteroids ... where not known to AZ.)

    Thx a lot. 😃

    I got fooled by the image descriptions in my plot because they were the other way round (because the starting circles were too near to each other). The lower circle was labled above the circle and the upper circle was labelled below the circle. Thus I thought that the lower trajectory would belong to (427377).

    But it is of course (41373).

    Yea, I have had the same problem at times.
    I'll make a note about this, next time I send a message to the Lowell site.
