enhanced conditions S Aus/Antarctic region. Daytime sporadic-E 
conditions observed at some stations. Solar radio noise again 
observed during sunlight hours on the Culgoora Radiospectrograph 
and IPS Antarctic Riometer network, but intensity has declined 
significantly from the levels of previous days. Expect similar 
HF conditions next three days with low latitude variability and 
declining solar radio noise emissions. Possible minor disturbances 
Antarctic region on days one and two.
