A paper with preliminary analysis has been submitted, but we're gonna need more data in future encounters to really nail down the specs on this. It's a noise-level detection, so a few more photos would also be nice

That’s amazing!

We think so! WISPR was definitely not designed to find this kind of feature!

Very cool... I've been waiting for this. If you'd like a mass-loss model to compare against, I published one a few years ago... https://ui.adsabs.harvard.edu/abs/2016EM%26P..118...51C/abstract …pic.twitter.com/qDdBwELjlR

Yeah, this is something we plan to look into once we get deeper into the data (which'll happen once we have a couple more datasets under our belt). Unfortunately we missed seeing Phaethon itself earlier this year, but at least we have a trail!

Very cool Karl! Does your data give any indication of the mass of the stream shown? And whether it has been recently deposited?
-
We have estimated the mass of the entire (full orbit) of the trail and it's very much closer (though a tad under) the Geminid mass (very old stuff). Certainly MUCH more than Phaethon produces at perihelion. But this is all prelim analysis!
