COMMENT: Equatorial and mid-latitudes were enhanced at certain
times in the UT day raising the regional T index above monthly
median. The enhancement is probably from enhanced ionising solar
EUV radiation as there are now 5 active regions. The variability
may be from geomagnetic variability over the last 24h from fluctating
solar magnetic field. An extended recurrent coronal hole across
the solar equator is likely be geoeffective in 3-4 days, and
MUFs could be suppressed back to monthly averages.
