LATEST SOLAR NEWS (Courtesy of Spaceweather News):
AURORAS EXPLODE OVER FINLAND: Earth is entering a stream of solar wind flowing from a sprawling hole in the sun’s atmosphere. First contact with the gaseous material on March 22nd sparked a bright display of auroras over Scandinavia. “The sky literally exploded right above our heads,” says Didier Van Hellemont, who sends this picture from Luosto, Finland:
“We enjoyed fine auroras for several hours as we walked through the woods from a snow-covered mountain in northern Finland,” says Van Hellemont. “And I hope there will be more in the nights ahead.”
Indeed there will be. Earth is only in the outskirts of the stream now. Our planet is about to move deeper into the stream where we will experience faster-moving rivulets of solar wind, with speeds exceeding 600 km/s (1.3 million mph). NOAA forecasters estimate a 55% chance of G1-class geomagnetic storms on March 24th and 25th.

ARLP012 Propagation de K7RA
At 2332 UTC on March 22 the Australian Space Forecast Centre issued
a geomagnetic disturbance warning for this weekend, March 24 and 25.
“Expect the geomagnetic activity to increase to mostly Active levels
with isolated periods of Minor to Major Storm levels due to a high
speed solar wind stream associated with a negative polarity coronal
hole becoming geo-effective”.
In last week’s report, ARLP011, there were no sunspots over the
reporting week. On March 15 one new sunspot appeared for a sunspot
number of 11, which is the minimum non-zero sunspot number. The
next day it was gone, then a new sunspot appeared March 17. Sunspot
numbers on March 17 and 18 were 15 and 13, then none for the rest of
our reporting week, March 19 to 21. So the average daily sunspot
number increased from 0 over the previous week to 5.6 over the most
recent 7 days, ending Wednesday March 21.
Average daily solar flux over the same two periods increased from
67.7 to 69.3. Geomagnetic indices about doubled, with average
planetary A index changing from 7.1 to 14.4, and mid-latitude A
index increasing from 5.7 to 11.3.
Predicted solar flux is 68 on March 23 through April 2, 69 on April
3 and 4, 70 on April 5 to 15, 69 on April 16 and 17, 68 on April 18
to 29, 69 on April 30 through May 1, and 70 on May 2 to 6.
Predicted planetary A index is 8, 22, 24, 18 and 8 on March 23 to
27, 5, 15, 10 and 8 on March 28 to 31, then 5 on April 1 to 9, then
8, 15 and 20 on April 10 to 12, then 15 on April 13 and 14, then 8
and 12 on April 15 and 16, 18 on April 17 to 19, 15 and 8 on April
20 and 21, and 5 on April 22 to 25, 8 on April 26 and 27, and 5 on
April 28 through May 6.
The spring equinox began at 1615 UTC on Tuesday, March 20 in the
Northern Hemisphere. At that moment solar radiation was equally
distributed between the Northern and Southern Hemisphere. Except
for the low solar activity, the beginning of spring should be an
ideal time for worldwide HF communication.
Geomagnetic activity forecast for the period March 23 to April 17,
2018 from F. K. Janda, OK1HH.
“Geomagnetic field will be:
Quiet on April 3, 7 to 9
Mostly quiet on March 28, 30, April 6
Quiet to unsettled on March 26 and 27, 31, April 1 and 2, 4 and 5,
16 to 18
Quiet to active on March 23 to 25, 29, April 10 and 11, 13, 15
Active to disturbed on March 26, April 12, 14
Solar wind will intensify on March 25 to 28, (31,) April (6 to 8,)
10 to 18.
Conditions have been variable. Last Tuesday saw a small ‘lift’ in conditions and some distant repeaters in the West of the UK were heard whilst out mobile in the Shoreham/Steyning areas. Auroral contacts are also likely this week.
Beacons often heard in our area:
GB3WSX – IO80QW – 70.007 MHz
GB3BAA – IO91PS – 70.016 MHz
F1ZXK – JN18KF – 144.438 MHz
F5ZSF – IN88GS – 144.409 MHz
