Hello—

                I attach three graphs, which extend the time series from the 2020 Space Weather paper  (DOI 10.1029/2020SW002543) with another six months of data (thanks, as always, to Jody for making this available in near real time).  There are two plots of LET spectra, both multiplied by the square of the abscissa to reduce the many-decade dynamic range; one magnifies the H/He region where statistics are best, so that differences can more readily be seen.  There is also a plot of the 4-pi dose rate, calculated per the appendix of the paper for the spectrum measured in each six-month period.  As discussed in that paper, intensity during the recent solar minimum rose a few percent above the already record-setting intensity at the start of the mission; as of the most recent period, it has finally fallen back (slightly) below the level at the start of the mission.

Hope this helps in pointing out CRaTER’s utility to Artemis et al.—
