> This is Field Day weekend! Conditions don't look bad, although there
> is the chance of geomagnetic conditions becoming unsettled.  This
> week the sunspot numbers have improved, while geomagnetic conditions
> were quiet, which is a great combination. Average daily sunspot
> numbers rose over 50 points from last week to 116. Average daily
> solar flux was up almost 18 points to 113.7. Sunspot numbers were
> the highest on June 20 and 21, Sunday and Monday, and both the
> planetary and mid-latitude A indices were very low, in the lower
> single digits.
> 
> Look at http://www.sec.noaa.gov/ftpdir/indices/DGD.txt and you can
> see the K index at 1 and 0 at all locations for several days.
> 
> Sunspot groups 634 and 635 provided most of the activity, and today
> they are moving out of view. As a result, predicted sunspot and
> solar flux numbers are a bit lower, with the solar flux forecast for
> Friday through Monday, June 25-28 at 100, 95, 95 and 90. The
> predicted planetary A index for the same four days is currently at
> 12, 12, 15 and 15. This is due to weak high-speed solar wind from a
> recurrent coronal hole coming into view.

> K7RA will operate some this weekend, under Class C, which is for
> stations in vehicles capable of operating while in motion, and
> normally operated in this manner. I'll probably be on 15 and 20
> meters, both phone and CW, and 10 meters if it shows any life, and
> the operating style will be casual. One of the fun things about the
> Field Day operating activity is that the paperwork is very easy.
> When submitting a contest entry, you only turn in a list of stations
> worked, sorted alphanumerically and divided by band and mode, along
> with a summary sheet.
> 
> Unlike the ARRL Sweepstakes or DX contests, you will never lose
> points for incorrectly copying the exchange from the other station
> or the time of the contact because you don't even report it. Only
> the call sign is recorded in the appropriate band/mode list. There
> are no multipliers for numbers of states or sections worked or for
> DX. I'll probably just sort my call sign lists on a laptop with a
> simple text editor or word processor while operating, then e-mail in
> the results. See http://www.arrl.org/contests/announcements/fd/ for
> rules.
> 
> For this year's Field Day, 20 meters will be your best band, and
> possibly 15 as well. 10 meters may be good for some sporadic E skip.
> 40 and 80 meters should be good after dark. Run some numbers using a
> sunspot count of 100 or 105 and a K index of 2 or 3 on W6ELprop to
> get some ideas of where openings might point to at different times.

> Sunspot numbers for June 17 through 23 were 106, 118, 90, 142, 139,
> 113 and 104 with a mean of 116. 10.7 cm flux was 111.3, 107.8,
> 112.7, 119.1, 115.8, 116.7 and 112.5, with a mean of 113.7.
> Estimated planetary A indices were 7, 8, 5, 3, 4, 4 and 5, with a
> mean of 5.1. Estimated mid-latitude A indices were 7, 10, 4, 3, 3, 1
> and 2, with a mean of 4.3.
