An interesting step toward understanding the substantial brightness variations seen from JWST came from Peter Plavchan at George Mason University. He reported a 3-hour light curve which had remarkable symmetry. where the timing and amplitude of four peaks were almost perfectly mirrored after a brightness minimum. He shows a graph with the time overlay in https://twitter.com/PlavchanPeter/status/1481333935602913280 <https://twitter.com/PlavchanPeter/status/1481333935602913280> With a little imagination, a similar pattern centered between two peaks may be there in the earlier light curve from the University of Hertfordshire: https://twitter.com/BayfordburyObs/status/1479091173234987011 <https://twitter.com/BayfordburyObs/status/1479091173234987011> I haven’t yet followed it for so long - this may be incentive.
