2.1 Comments on Solar Activity.
Solar activity was at moderate to high during the beginning
and end of the month. A lull in flare activity was observed just
after the middle of the month. A total of 47 flares were
observed, 45 M class events and 2 X class events.
The largest flare for the month was an X1.1 on Nov 25. Four proton
events were observed during the month.

3. GEOMAGNETIC DISTURBANCES (for Australian Region)
DATE COMMENTS
01 Nov 01: Active periods
05 Nov 01: Active to Minor Storm, two weak sudden impulses observed
1555UT (14nT) and 1753UT (12nT).
06 Nov 01: Severe Storm Levels, following a moderate sudden impulse
of 84nT at 0151UT.
15 Nov 01: Weak sudden impulse of 14nT observed at 1509UT, no
significant activity followed impulse.
19 Nov 01: Unsettled to Active, a weak sudden impulse of 16nT was
observed at 1815UT.
24 Nov 01: Severe Storm Levels, a weak sudden impulse of 35nT was
observed at 0501UT, and a strong sudden impulse of 102nT
was observed at 0556UT.
25 Nov 01: Quiet to Active, a weak sudden impulse of 20nT was observed
at 0535UT.
Most of the disturbances this month were due to coronal mass ejections.
Severe storm levels were observed on 06 Nov and 24 Nov, with the local
A index reaching 86 and 127 respectively.
===============================================================================
4. IONOSPHERIC DISTURBANCES (for Australian Region)
06 Nov 01 Northern region MUFs enhanced 20%
Southern region MUFs near normal to depressed -20%
07 Nov 01 Northern region MUFs enhanced 20%
Southern region MUFs depressed -30%
24 Nov 01 Northern region MUFs enhanced 25%
Southern region MUFs depressed 30% second half of UT day.
25 Nov 01 Northern region MUFs mildly depressed.
Southern region MUFs depressed 20-40% most of UT
day.
MUFs during the month were generally 15-20% above IPS predicted
monthly values for November. Strongly depressed conditions were
observed southern Aus/NZ region during intervals 06-07 Nov and
24-25 Nov in association with coronal mass ejection induced
geomagnetic storm activity.
