ARLP052 Propagation de K7RA

Solar activity was a mixed bag over the week of December 18-24

compared to the previous seven days. Average daily sunspot numbers

were down 12.5 points to 132.9, while average daily solar flux rose

22.9 points to 190.6.

A peak of geomagnetic activity occurred on December 22 and 24, with

planetary A index at 20 and 17. Three CMEs hit earth on December

21-22.

The latest prediction (December 25) from NOAA/USAF forecasters has

solar flux at 140 December 26, 145 December 27-28, 150 December

29-31, and 140 January 1-3. After that it climbs, from 145, 150, and

155, January 4-6, then 165, 170, 175 and 180 January 7-10, 185

January 11-12, 190 and 200 January 13-14, 205 January 15-17, then

peaks at 210 on January 18. Flux values then decline to a low of 140

on January 18-20.

Predicted planetary A index from the same source is 5 on December

26, 8 on December 27, 10 on December 28 through January 1, then 12,

25, 15 and 10 on January 2-5, 8 on January 6-7, 10 on January 8-9, 8

Lee, W4KUT said he was unable to participate in the recent ARRL 10

Meter Contest, but "I did venture into 28 MHz CW territory and, WOW!

I sent a quick response to a CQ from W1AW/7 (Comstock, NV) 2329 UTC

on December 12, S9+ on both ends.

"I tell you, I've got to do more 10M activity. The band is hot these

days!

"I would urge American Hams with a Tech license or better, to check

out 10 Meters, and yes, 10 Meters is available to Technician

Licensees; CW, RTTY/Data and Phone (SSB).

"According to the ARRL website: 28.000-28.300 MHz: CW,

RTTY/Data--Maximum power 200 watts PEP 28.300-28.500 MHz: CW,

Phone--Maximum power 200 watts PEP"

Jon Jones, N0JK (EM28) in Kansas writes "A strong winter Es opening

on 50 MHz between the Midwest and eastern states December 19 from

1430-1730z. Here in eastern Kansas, K1RO FN33 and K2UU FN30 were

very loud around 1600z. No links noted to F2 to Europe or Africa."

Jon is a frequent contributor to this bulletin, and he also writes

"The World Above 50 MHz" column for QST Magazine.

The site http://www.arrl.org/the-world-above-50-mhz gives some

details about the column and a little bit of history, where it says

it "has appeared in QST for more than 60 years, making it one of the

longest running columns. It originated as 'On the Ultra Highs,'

which debuted in December 1939 under the direction of Ed Tilton,

W1HDQ."

While true the column has run for more than 60 years, currently it

has run for over 75 years. It says that W1HDQ was the first

columnist, and I've mentioned before that Ed was also the author of

this weekly bulletin until 1991, when Ed became ill, and I offered

to write the bulletin for one week. I've been at it ever since, and

I expect that Ed was the original originator of this bulletin, but I

can't find anyone who knows when it began. I first copied it on CW

from W1AW in 1966, when I was a very young ham.

From time to time I've paged through my old QSTs from the 1950s and

1960s looking for a reference to the bulletin, but have found none.

Maybe it is time to apply some modern search tools to the effort.

related to meteor activity. This site is run by Chip Sufitchi, N2YO,

who is in the Washington DC area, and uses an SDR receiver tuned to

55.23693 MHz with a Yagi pointed toward a channel 2 television tower

in Canada. The page also features both a spectral and a waterfall

display.

Here is an interesting article from the Daily Mail about a new space

telescope: www.dailymail.co.uk/sciencetech/article-2884213/ .

One more report came in concerning working Bob, ZL1RS on 6 meters,

reported in last week's Propagation Forecast Bulletin ARLP051. Bob

Miles, K9IL in Martin, Tennessee (EM56) wrote on December 19 that he

heard ZL1RS as good as 579 over three evenings around 0100 UTC.

This is the last propagation bulletin of 2014, and on a personal

note, back in 1999 in propagation bulletin 52 I made a brief mention

of completing my seventeenth season playing the Grandfather

character in Pacific Northwest Ballet's lavish production of

Nutcracker.

http://www.arrl.org/w1aw-bulletins-archive/ARLP052/1999

And now we come to the end of the run. This weekend I am completing

my thirty-second season in this same role, but this is the final

year of this production, and my character doesn't appear in the

brand new 2015 production. This began for me with a series of

unlikely events in 1983 when Don Walter, W7NG recommended me for

this role in a brand new Nutcracker with sets and costumes by

children's book author and illustrator Maurice Sendak. It was a huge

hit, and as many as 46 performances are done (but I am not in all of

them) every December. The house holds an audience of 3,000 people.

This became hugely popular, so now that this is ending, every

performance has sold out. By noon the day after Thanksgiving, ticket

sales for this final Nutcracker hit seven-million dollars.

Every Christmas Eve we perform an alternative version, The Nutty

Nutcracker, with all kinds of gags and pratfalls, improvised and

with no rehearsal. On December 25, 2013 this photo appeared in the

Seattle Times:

That's me in the brown coat, leaning back in shock, as I did not

know that the dancer crouching down on the right was going to

release a can of "Silly String" from an aerosol container in his

right hand, nor did I know that photos were taken. I sneak up on him

as he is about to let go with a tremendous dramatic sneeze while

facing the audience downstage center so that I can react and express

annoyance. He held the can so it appeared that it all projected from

his face.

On opening night this year at the end of November I gave a backstage

tour to a writer, who came up with this:

Here is an article about the big change:

I will be sad after the final last performance, which begins at 2330

UTC on Sunday, December 28. I am the only player remaining from the

premiere season, and won't know what to do with myself in December

2015. But I love this company so much that I may come back as a

volunteer Kid Wrangler, herding the children from dressing rooms to

the stage and back. I am sad, but not bitter. It has been an

incredible run, far beyond what I ever could imagine!
