COMMENT: Ionospheric conditions were mostly normal in the Australian
region during UT day, 23 June. Expect normal to minor enhancements
in the Australian region due to an increase in sunspot activity
(EUV levels) for the next three days. Proton event 10 MeV integral
flux exceeded 10 PFU, expect possible minor impacts on HF radio
in polar regions.
