Hello—

                I attach the usual trio of figures, adding another six months of data to the CRaTER LET spectrum and the dose rate calculated from it, per our 2020 paper.  The most recent intensities (black curves in the two spectrum plots) are almost back down to the level of the 2014 solar maximum (green curves).  I’m thinking of submitting this, along with the data files that go into the plots, to the Zenodo repository so they will be available for others to use.

Happy new &%*#@! fiscal year…
