"Pseudo-MPEC" for C1AUGE1 = ZTF0Edd = 'Multijunk'

Created 2020 Oct 22 12:59:06 UT using Find_Orb

Click here for an explanation of pseudo-MPECs

TLEs are available for this object, and for some of the other objects on these pages. Because it is an ETBO, the predictions are going to be somewhat poor.

This was picked up five times before it was recognized as an artsat. CSS finally got it as C1AUGE1 and stayed on it a while. It helped that we also had data from (H01) Magdalena Ridge, for parallax. That got us a decent orbit, one which was both unambiguously an artsat and one that could be linked to observations of ZTF0Edd made four nights earlier from ZTF. That, in turn, got us linkages to three previous objects from NEOCP.

The orbital elements are similar to those that would be expected of 'Multijunk', the ETBO in a 2.3-day orbit that has been observed, off and on, since 2017. The similarity is a little rough, because the last previous observations were from April 25. (Actually, that page needs to be updated to include said observations...)
