SOLAR TERRESTRIAL REVIEW FOR 17 MAY TO 23 MAY
Solar activity between 17 May and 23 May ranged from very low to high.
Departing Region 6619 provided the most impressive activity during the
period. At 05:45 UT on 18 May, a major class X2.8/1N Tenflare erupted from
Region 6619. The location of the flare was N32W84. The flare was associated
with a moderate intensity Type II sweep and a weak Type IV, as well as with a
5,700 s.f.u. radio burst at 2695 MHz. Immediate concerns were raised
concerning a possible proton bombardment from this event. Fortunately, no
significant protons were detected. A minor proton enhancement was observed
(the suspected cause is the class X2.8/1N flare) and remains in progress at
the present time. Although proton levels never surpassed event thresholds,
the duration of the enhancement has been relatively long. Proton levels are
now very near background levels.
Aside from this major flare, no significant solar events occurred.
Other items of interest included several filament disappearances in the
10-20 degree range. One of these is suspected of producing a sudden magnetic
impulse of around 40-55 nanoteslas (43 nT at Boulder, 51 nT locally) at 00:18
UT on 22 May. This event has been followed by generally unsettled to active
geomagnetic conditions since then.
Geomagnetic activity on 17 May was generally active over most middle
latitudes, while major geomagnetic storming was observed over the northerly
middle and high latitudes. The activity was preceded by a SI of 40-50 nT
earlier on the 16th. Significant levels of auroral activity were observed
over many middle latitude locations. Equatorward auroral oval expansion was
observed during this storm period. Auroral activity was reported as far
south as southern Montana, and northern South Dakota over the northern
hemisphere, while Australian observers also reported observing auroral
activity on 17 May. No low latitude auroral activity was reported over the
northern hemisphere. Geomagnetic and auroral activity then subsided until 22
May, when some resurgence was observed over the higher latitudes.
HF radio propagation conditions were normal to below normal throughout
the week. Ionospheric conditions were rather weak during the period. HF
propagation on 10 meters was also below normal. However, an interesting
phenomena has occurred on the VHF bands lately. Unusual openings on 6 meters
have been observed by many stations from the high to the low latitudes. The
openings have been generally observed over a period of a few hours with slow
fading and relatively low signal strengths. These conditions have so far
been reported throughout most of Canada and over parts of the U.S. The cause
of these openings has not yet been firmly determined.
SHORT TERM SOLAR TERRESTRIAL FORECAST
Solar indices are expected to bottom out this week. Region 6615, which
was responsible for six M-class flares last rotation, is expected to return
back to the eastern limb on 25-26 May in the southeastern quadrant near S10.
This region may return in a configuration capable of producing M-class
flares. Indices are then expected to begin a slow rise until 30 May to
01 June when several other major regions are due to return (including Region
6619). Thereafter, indices should rise rapidly toward a peak of between 230
and 245 (10.7 cm solar flux vlaues) near 07 - 10 June. There is a risk for a
few more isolated major flares with the rotation of these active regions back
into view. Proton activity cannot be discounted.
Geomagnetic activity has increased lately to generally unsettled to
active levels. Geomagnetic activity is expected to surpass minor storm
levels between 25 - 27 May over the middle latitudes, while high latitudes
may observe major geomagnetic storming. Activity is expected to peak during
the 25-27 May period (target date is presently 26 May) with planetary
A-indices between 35 and 60. High latitudes could observe isolated
(localized) A-indices of between 45 and 100 (with values between 45 and 75
being more probable).
Auroral activity will become moderate to very high over the northerly
middle and high latitude regions during the 25-27 May period. There is a
small risk for visible auroral activity over the lower latitudes,
particularly after the Moon sets. Lunar phase will interfere with attempts
to view auroral activity.
HF propagation conditions will become increasingly degraded until 26 or
27 May. Thereafter, a slow and gradual improvement will take place as
ionospheric conditions begin to recover and strengthen. A full recovery to
more normal conditions is not expected until early June. Propagation
conditions during the disturbed period will be rather poor, particularly over
the high and northerly middle latitudes. Fairly significant levels of
fading, noise and distortion are anticipated for most middle and high
latitude paths on 26 and 27 May (possibly 25 May as well). Lower latitudes
may not be as strongly affected, but will still suffer degradation in signal
qualities and signal range.
There is a good opportunity for VHF auroral backscatter communications
above 50 MHz (50 - 144 MHz should be good) on 25-27 May over the high and
middle latitudes. Provided auroral and geomagnetic activity reach forecasted
intensities, backscatter conditions should be possible over fairly wide
areas. Conditions should remain fairly favorable between 25-27 May, but may
also be possible over more localized areas on 28 May.

NOTES:
Predicted geomagnetic activity is based heavily on recurrent
phenomena. Transient energetic solar events cannot be predicted reliably over
periods in excess of several days. Hence, there may be some deviations from
the predictions due to the unpredictable transient solar component.
