Hello, world! This is the mission account for the Polarimeter to UNify the Corona and Heliosphere (#PUNCH) mission. Follow for announcements, milestones, and science. We launched just a few days ago, but data will be flowing before you know it. First light is about three weeks from today. ☀️🛰️

Now it can (finally) be told. We've been tracking Comet 3I more or less continuously with PUNCH. Everything is fine. 3I is definitely very interesting – but it is most definitely *not* an alien spaceship undergoing maneuvers, no matter what that Boston guy says. ☀️🛰️🔭🧪 #3I #comet #not_aliens

I don't have the Polarimeter online presently due to other experiments. So measured the period the old fashioned way.
The TIANDU-2 signal is also fading at the same rate of about 16.9 seconds. 🛑

PUNCH @punch-mission.bsky.social found out we are good at comet tracking, even as we calibrate/refine our solar wind imaging pipeline. In the last 3 months, we've tracked 3 notable comets with images every 4 min, around the clock: SWAN, Atlas, and Lemmon. PUNCH data are free to get and use. ☀️🛰️🧪🔭

I'd like to report an error in my Galileo analysis. I incorrectly calibrated the polarimeter. I thought I had tested a new feature properly but turns out I didn't. 🙄
'Turns' out (pun intended) that the Galileo is slowly rotating and has a RHCP signal and it rotates MUCH faster in eclipse! 🧵⬇️
