Good morning and welcome to the first day of UPDATE MARCH 16 SOLAR FLARE
If you've been wondering why band conditions have been poor lately . . . . read on. As the sun reaches its maximum 11 year peak in activity additional solar flares can be expected. Fortunately, propagation has gradually been improving lately with frequent openings on 12 and 10 meters. And now a solat flare!
Here is an updated look at the visible solar disk on Wednesday. Solar activity during the past 24 hours was moderate. Region 2297, currently in a gradual state of decay, produced an M1.0 solar flare at 23:34 UTC. A weak CME was associated and directed away from Earth. The formerly threatening region continues to move closer towards the west limb. New sunspot 2302 located in the northwest quadrant continued to expand overnight and now has a Beta-Gamma magnetic layout. The active region is currently producing C-Flares and could produce an isolated M-Flare as it too approaches the west limb. No Earth directed coronal mass ejections were observed during the past day.
Minor (G1) geomagnetic storming continues on Wednesday morning following a hectic day on Tuesday which featured periods of severe (G4) storming at higher latitudes in the wake of a CME impact. Activity is expected to gradually decline to lower levels during the next 48 hours. Sky watchers at high latitudes should remain alert as geomagnetic flareups will be possible.
Information: This data is measured by the GOES-15 satellite which does monitor Solar X-Rays. This information is very important in tracking solar flares. Large X-ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere. Solar flares can also trigger geomagnetic storms which produce aurora and nice openings on VHF.
What is a Solar Flare?
A solar flare is a violent explosion in the Sun's atmosphere with an energy equivalent to tens of millions of hydrogen bombs. Solar flares take place in the solar corona and chromosphere, heating plasma to tens of millions of kelvins and accelerating the resulting electrons, protons and heavier ions to near the speed of light. They produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths from long-wave radio to the shortest wavelength Gamma rays. Most flares occur around sunspots, where intense magnetic fields emerge from the Sun's surface into the corona. The energy efficiency associated with solar flares may take several hours or even days to build up, but most flares take only a matter of minutes to release their energy.
Solar Flare Classifications
Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square meter, W/m2) of 100 to 800 picometer X-rays near Earth, as measured on the GOES spacecraft. Each class has a peak flux ten times greater than the preceding one, with X class flares having a peak flux of order 10-4 W/m2. Within a class there is a linear scale from 1 to 9, so an X2 flare is twice as powerful as an X1 flare, and is four times more powerful than an M5 flare. The more powerful M and X class flares are often associated with a variety of effects on the near-Earth space environment. Although the GOES classification is commonly used to indicate the size of a flare, it is only one measure.
Coronal Mass Ejection (CME)
A coronal mass ejection (CME) is an ejection of material from the solar corona, observed with a white-light coronagraph.
The material consists of plasma consisting primarily of electrons and protons (in addition to small quantities of heavier elements such as helium, oxygen, and iron), plus the entrained coronal magnetic field. When the solar cloud reaches the Earth as an ICME (Interplanetary CME), it may disrupt the Earth's magnetosphere, compressing it on the dayside and extending the nightside tail. When the magnetosphere reconnects on the nightside, it creates trillions of watts of power which is directed back towards the Earth's upper atmosphere. This process can cause particularly strong aurora also known as the Northern Lights (in the Northern Hemisphere) and the Southern Lights(in the Southern Hemisphere). CME events, along with solar flares, can disrupt radio transmissions, cause power outages (blackouts), and cause damage to satellites and electrical transmission lines.

SOLAR FLARE MARCH 16, 2015
Space weather predicted moderate disturbance with geomagnetic storms reaching the G2 level. Solar radiation storms reaching the S1 level were expected. Radio blackouts reaching the R1 level occurred. Many Ham Radio stations are reported auroral flutter on 80 through 10 meters. Check it out.
A long duration C9 flare peaking at 02:13 UTC (March 15) around region 2297 may have produced a coronal mass ejection (CME). More updates on this once new coronagraph imagery is available. Image below is courtesy of the Solar Dynamics Observatory (SDO) using the 94 angstroms channel.
CME UPDATE #2: A geomagnetic storm watch has been issued for the middle of the upcoming week. Modelling completed by the Space Weather Prediction Center (SWPC) is calling for a potential glancing blow CME impact by late Tuesday or early Wednesday. Although directed mostly to the west, sky watchers should remain alert should the flank of the interplanetary shock (IP shock) impact our geomagnetic field.

Here's some Northern Lights photos taken by various photographers. The beautiful light display in the sky are cuased by solar radiation striking the Earth's atmosphere and electrofying the air molecules, causing them to give off lioght of various colors.
INTERPRETATION OF SOLAR DATA
“A” INDEX ….. 1-6 BEST 7-9 FAIR 11+ BAD - Represents overall geomagnetic condition of the ionosphere over a given 24 hour period.
“K” INDEX ….. 0 or 1 BEST … 2 OKAY .… 3+ BAD .…. 5 VERY BAD - This is the overall geomagnetic condition of the ionosphere averaged over the planet over the past 3 hours. K index indicates geomagetic storms. Below 10 MHz, K of 5+ increases noise level appreciably, K of 7+ degrades HF significantly.
“SFI” ….. 70 NOT GOOD … 80 GOOD … 90 BETTER …100+ BEST - SFI is the Solar Flux Index and is a measure of total radio emissions from the sun.

THE SPRING SEASON IS SOON TO ARRIVE IN IN HOWARD, PENNSYLVANIA
This past winter has been unusually cold, breaking or nearly breaking weather records. It was so cold here that all the house doors froze shut and I couldn't let the dog out. Most of these frigid days were spent on the air in the ham shack. Fortunately we were able to install the 17 meter monobander on the 80 ft tower before cold weather.

40 METER CENTER FED DOUBLE EXTEND ZEPP ANTENNA
This is my favorite antenna. It tunes all bands 80 through 10 meters. and is fed with six inch wide homebrew open wire using #10 wire and 1/2 inch x 7 inch PVC pipe spacers at 1 foot intervals. A little heavy but very rugged.
Using PVC pipe as feed through insulators through the exterior house wall, down through the ceiling tile,into the radio shack and onto the MBVA Nye Viking tunner. I learned this little trick from Morris, W3SCB.
> Three towers are being added to the ham station this year. Land has been cleared to accomodate the main tower which will support a Hygain TH7DXX for 10, 15 & 20 meters. It will also help support a North-South fixed position 3 element delta loop for 40 & 30 meters and East-West 3 element delta loops for 40 and 30 meters.
< This 80 ft Rohn 25 tower will support a 4 element 17 meter monoband beam, a 2 meter 22 element beam, and one end of the 135 ft dipole.
> TOWER #3 The 80 ft Amerite tower NOW HAS a 12 meter 3 element monoband beam. It will also help support the East-West fixed position 3 element delta loop for 40 & 30 meters. It will also hold up one end of a 135 ft dipole fed with openwire into a tuner.
Getting the TH7DX up sure put a smile on my face!

Ron (K3SEW), Rich (Son-in-law), and Mick (W3FJ) making final plans to get the 7 element tribander up on the 70' tower.
A slide ramp or trolly made from stainless steel cable is being used. The photographer was a litle tipsy!
Paul McBride (Mick, W3FJ) wants to pull it up using the Kubota and a single fixed pulley at the tower base and the ginpole.
Now lets see . . . what is the best Boy Scout knot to use? How bout the boweline.
And away we go !
Come on fellas get it up here. I can't beleive I'm still doing this stuff at age 72!
The temporary and permanent guys became big problems and we didn't get her up on October 14.

Inspired by my neighbor, K3KOQ, and classmates in college physics, K3QIA and K3AKZ, I became interested in amateur radio at age 20 and received the Novice license, KN3SEW in 1962. Received General Class that same year and became Extra Class in 1971. K3SEW is the only callsign ever held and I operated with it from various residences: Shamokin, PA; Stone Ridge, NY; Sunbury, PA; North Windham, ME; Northumberland, PA and from my present QTH in Howard, Centre County, PA.
As a science teacher, a school ham radio club was always part of my curricula and as a professional executive with Boy Scouts of America, Jamboree On The Air was a major annualevent. In addition to sharing ham radio with youngsters, I enjoy building antennas and DXing. My favorite mode is definitely CW but I do have a microphone and a teletype station.
Station equipment includes: Icom 781 Transceiver, Alpha 87 & SB220 Amplifiers, 2 MBVA Nye Viking Antenna Matching Networks; AEA Morse Machine and various homebrew stuff including several homebrew computers. Computer logging, rig control, and internet resources are used.
Antennas include: TH7DXX 10, 15 & 20 triband beam; TB3 10, 15 & 20 triband beam; 12 Meter AJ1T monoband beam; 204BA 20 meter monobander; 40 meter 3 element delta loop; 80 meter / multiband horizontal loop using open wire feed; 40 meter / multiband center fed zepp, 160 meter slopper; and reference dipoles for 80, 30, 17 & 12 meters. I’d build a 160 meter vertical with all the radials if I know I wouldn’t move again!
Awards include: Triple Play W.A.S. #7, WAC, We The People; 5-Band WAS,DX Challenge 1784/1829,Mixed, Phone & CW DXCC;, 8-Band DXCC, and DXCC Honor Roll. Total Confirmed Countries = 339. Confirmed Current Countries = 324.

WINDHAM, MAINE QTH
Antennas in Windham, Maine were the 204BA 20 meter monobander shown above.
Others were a Th7DX Tribander, 80-10 meter Vertical Loop, and a 40 meter Center Fed Zepp.
SUNBURY, PENNSYLVANIA QTH
Equipment at the Sunbury QTH was the Drake B Line, Heathkit SB220, homebrew 813 transmitter & TZ40 AM modulator.
Ron, K3SEW, and son, Adam, WA3THG.
Antennas at the Sunbury QTH were a 3 element qubical quad, 80 meter inverted vee, 40 meter double extended zepp.
Because of high maintenance the quad was replaced with a 204BA 4 element 20 meter monobander and a 22 element two meter beem above and an 80 meter inverted vee side mounted off the tower at Sunbury. That's me on the tower at age 28. I'm age 70 now and still climbing!
STRAIGHT KEY CENTURY CLUB MEMBER #4872
HOMEBREW 80~10 ANTENNA TUNER – Built from QST Article, June 1964. A transmatch (antenna tuner) for 80~10 meters at 1 KW. Ideal for a new Ham to get started. QST article and photos available upon e-mail email@example.com. Ron, Howard, PA, 814-625-2468. $55 + shipping or arranged pick up.
Although CW is my favorite mode, I've always enjoyed RTTY. Back in the 80's I was very active in RTTY ART using Model19 and Model 28 teletype machines. Since then technology has greatly changed. Now I'm operating FSK using the W3YY board and the MMTY computer software. RTTY WAS & DXCC on all bands have become the new challenge.
I'm not a psychotic paper chaser. However, I've been acumulating Ham Radio Awards since I was first licensed in 1962.

"THE SEX LIFE OF AN ELECTRON"
A DISTORTED WAVE
ONE NIGHT WHEN HIS CHARGE WAS PLENTY HIGH, MICRO FARAD DECIDED TO GET A CUTE LITTLE COIL TO LET HIM DISCHARGE. HE PICKED UP MILLA AMPS AND TOOK HER FOR A RIDE ON HIS MEGACYCLE. THEY RODE ACROSS A WHEATSTONE BRIDGE AND STOPPED IN A MAGNETIC FIELD BY A SMALL STREAM OF EDDY CURRENTS.
MICRO FARAD, ATTRACTED BY MILLI AMPS CHARACTERISTIC CURVE, SOON HAD HER AT MINIMUN RESISTANCE AND HER FIELD WAS FULLY CHARGED. HER RIPPLES WERE PULSATING HEAVILY AND HER CAPACITORS WERE GETTING HOT AND LEAKY. HE TRIED TO TEST HER SHORT BY PULLING OUT HIS HIGH VOLTAGE PROBE AND INSERTING IT IN PARALLEL. HE BEGAN TO SHORT CIRCUIT HER SHUNT.
FULLY EXCITED, MILLI AMPS SAID: MHO! MHO! MHO!
AT LAST SYNCHRONOUS MOTION WAS TAKING PLACE BETWEEN THE TWO COMPONENTS. WITH HIS TUBE AT MAXIMUM POTENTIAL AND HER COIL VIBRATING DUE TO EXCESSIVE CURRENT FLOW, SHE SOON REACHED HER MAXIMUM PEAK. BUT MICRO FARAD WAS LAGGING BEHIND AND ONLY AFTER SEVERAL TIME CONSTANTS DID SHE FINALLY REACH SATURATION AND THERMONIC EMMISSION TOOK PLACE.
THE EXCESSIVE CURRENT IN HER SHUNT HAD HER PRETTY HOT AND MICRO FARAD'S CAPACITOR WAS RAPIDLY DISCHARGING. THEY FLUCTUATED ALL NIGHT AT TWO CYCLES PER SECOND, TRYING VARIOUS CONNECTIONS UNTIL HER MAGNET HAD LOST ALL OF ITS FIELD STRENGTH. FINALLY MILLI AMPS EVEN TRIED SELF INDUCTION.
WITH HIS BATTERY FULLY DISCHARGED, MICRO FARAD WAS UNABLE TO EXCITE HIS FIELD, SO THEY ENDED UP BY REVERSING POLARITY AND BLOWING EACH OTHER'S FUSES.
