JWST has a 15.5-16 magnitude now. It brightened by 1 magnitude after the sunshield was unfurled. @unistellar citizen scientists please continue to observe it in planetary defense mode as well. We have submitted an abstract to @SPIEtweets astronomy conference to present this work https://t.co/36tyzH7fRv
