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.
