the potential isomer, taken btw 21:00 on
July 2nd and 6:30 on July 3rd. Two examples

  Draft   Sat Jul 3 06:49:55 2021 The remote Canadian eager beavers (Guy &Iris)AnalysisList of possible spectra with isomer decayAttached is an example for the possible isomer
(on the left) next to the 70Se (right).

2nd 21h to Jul 3rd 05h, we couldn't find
a single example of a "smoking gun" isomer

  228   Sat Jul 3 04:33:50 2021 The remote Canadian eager beavers (Guy & Iris)AnalysisSlight shift in 70Se frequencyLooks like the beam is slightly drifting...the
70Se peak frequency is slightly shifted to
the left, by ~0.5 kHz compared to earlier

  227   Sat Jul 3 03:41:48 2021 The remote Canadian eager beavers (Guy & Iris)AnalysisSummed Spectra SummaryTo summarise the method of bulk summing the
spectra, I've created frequency vs time spectra
by using the e143_analyser.py script to stack

  226   Sat Jul 3 03:07:43 2021 The remote Canadian eager beavers (Guy & Iris)AnalysisSome single spectra (410 MHz) from 21-24hAttached are some single spectra with a rough
attempt to group them according to the different
ions that appear.
