WADARC meets at – Lions Hall, 21 Roberts Road, Lancing. BN15 8AR.
THE PAST WEEK
The “Search and Rescue” trip arranged by Alex, 2E0UMD was a great success, according to reports from those who attended. Members spent several hours at the facility and despite the crew being on a “shout”, there was a very informative tour of the facility.
Last Wednesday’s meeting was a talk on plastics by Norman, M0EBI who obviously knows his subject very well. Norman covered a brief history of how plastics came to be developed, followed by a trip into molecular science, showing how different plastics with varying capabilities can be made, sometimes by changing one small but significant component.

LATEST SOLAR NEWS (Courtesy of Spaceweather News):
RARE SOLAR MINIMUM SUNSPOT: Almost every day this month, the face of the sun has been utterly blank. Today, however, a new sunspot is growing near the sun’s southeastern limb, pocking the surface of our star with several Moon-sized dark cores.
Only on the eve of Solar Minimum would such a puny sunspot attract attention–and that is exactly where we are. Sunspot numbers are plummeting toward a deep nadir of the solar cycle expected to hit bottom in 2019-2020. For the foreseeable future, every sunspot is a rarity worthy of note.
This sunspot will probably remain small and quiet. But we could be wrong. Occasionally, potent sunspots emerge during Solar Minimum, unleashing powerful flares. Astronomers with backyard solar telescopes are encouraged to monitor this one … just in case.

ARLP011 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.
Monitoring ON0VHF has produced varying results from ‘unheard’ to 5/2/9 and back into the noise. This pattern can sometimes repeat may times in an hour. This could be due to ‘aircraft flutter’ or to changes in the Troposphere. There have been no enhancements this week due to temperature inversions.
Beacons often heard in our area:
GB3WSX – IO80QW – 70.007 MHz
GB3BAA – IO91PS – 70.016 MHz

During Norman’s lecture on plastics, he mentioned that the new Dreamliner aircraft is made from just two plastic mouldings, which makes it light and fuel efficient. I wonder how this affects its resistance to turbulence. Is it more likely to be bounced around the sky? Has anyone travelled on one yet?
