Based on 10 hours of observation so far, X67648 seems to be on an extremely eccentric orbit that takes it from <0.3 AU from the Sun to well over 4 AU. The min aphelion according to CNEOS is ~4.4 AU, and the max is ~8.7 AU (the nominal being ~5.6 AU). Although a large number of low-perihelion asteroids have aphelia extending nearly out to Jupiter, only a tiny handful actually cross Jupiter's orbit: 2013 JA36, 2016 BY14, 2006 OS9, 2010 JG87, 2017 HE4, 2011 GS60, and 2019 OC5. Of those, only the final three have aphelia beyond this object's nominal orbit.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Performing a search for similarities to known meteor showers, the definite closest relationship is the shower 00128/MKA - the Daytime Kappa Aquariids, compared here to X67648's preliminary orbit, as well as the hypothesized parent body of them, 2002 EV11:<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"> MKA X67648 2002 EV11<br></div><div dir="ltr" data-setdir="false">q ~0.23 ~0.25 0.232<br></div><div dir="ltr" data-setdir="false">e ~0.88 ~0.91 0.889<br></div><div dir="ltr" data-setdir="false">i ~2.2 ~0.3 11.60<br></div><div dir="ltr" data-setdir="false">node ~358 ~200 183.6<br></div><div dir="ltr" data-setdir="false">peri ~50 ~210 218.1<br></div><div dir="ltr" data-setdir="false">long ~48 ~50 41.7</div><div dir="ltr" data-setdir="false">H N/A 25.8 20.0</div><div dir="ltr" data-setdir="false">d (m) N/A ~24 ~340<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The possible relationship is fairly clear.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Followup would of course be very much appreciated. The object is currently circa magnitude 20.5 and dimming moderately quickly, at a very favorable elongation. The uncertainty will remain at a couple dozen arcseconds for the next few days, so really the main limiting factor for study is its dimming. Even if it is a meteor shower progenitor, I very much doubt that at this distance it would be outputting very much dust, but it couldn't hurt to pay special attention to any cometary activity for anyone observing it.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">~Sam<br></div></div></body></html>
