A new crop picture at Furze Knoll told us "50 weeks" (or one lunar year) from the eclipse season of late-August 2007 to the eclipse season of mid-August 2008 

Most new crop pictures which have appeared so far in the summer of 2008 have told us about the astronomy of eclipses. For example, West Kennett Longbarrow of June 9 told us "48 weeks" from a total lunar eclipse on August 28, 2007 to a total solar eclipse on August 1, 2008 (see www.cropcircleconnector.com/2008/westkennettlongbarrow/westkennett2008b.html). It also showed us a second symbol for 50 units of time, but whether that meant "days" or "weeks" remains unclear.

Ridgeway of June 15 showed us two outer rings ("total" or "annular") that contained 12 small balls each, in order to symbolize the 12 lunar months of any lunar year or eclipse season (see www.cropcircleconnector.com/2008/ridgeway/ridgeway2008a.html). The lunar year may contain either 12 x 29.5 = 354.4 or else 346.6 days, depending on whether one counts phase or eclipses. 

Furze Knoll of June 20 then showed us "Sun, Moon and Earth" in direct alignment as for any solar eclipse, with 50 half-Moon symbols on the outside to symbolize the 50 weeks between any two annual eclipse seasons. In order to understand Furze Knoll more clearly, first we need to learn some basic science about the periodic yearly appearance of eclipses!

Within any yearly period of 346-354 days (one lunar year), we may observe eclipses in two separate "seasons", separated in time from one another by roughly six months. For example, lunar eclipses occurred recently on these dates, separated by 12 lunar phase cycles or 354 days:

Solar eclipses occur half of a phase cycle (15 days) before or after a lunar eclipse. That is because lunar eclipses are seen on a full Moon, whereas solar eclipses are seen on a new Moon:

2006 March 29: total solar eclipse (+15 days)
2007 March 19: partial solar eclipse (+15 days)
2008 February 07: annular solar eclipse (-14 days)

2006 September 22: annular solar eclipse (+15 days)
2007 September 11: partial solar eclipse (+14 days)
2008 August 01: total solar eclipse (-15 days) 

In summary, both lunar and solar eclipses fall into two seasons twice a year. Any two eclipse seasons then repeat on average over a time period of 346.6 days or 50 weeks (see www.earthview.com/tutorial/patterns.htm or www.hermit.org/Eclipse/why_cycles.html).

Furze Knoll of June 20, 2008 showed "50 weeks" between eclipse seasons  

With that information in mind, it now becomes easy to understand why a new crop picture at Furze Knoll showed "50 units of time" (presumably weeks) for Sun, Moon and Earth to come into alignment during the eclipse season of mid-August of 2008:

Two previous seasons for eclipses were late-August of 2007 or mid-March of 2008 (50 or 25 weeks earlier).  

That new crop picture appeared just southeast of Furze Knoll at latitude 51 degrees, 23 minutes, 43 seconds N and longitude 1 degree, 56 minutes, 45 seconds W. Two nearby features of the landscape (see above right) were included to represent "Earth" and "Moon". Those two nearby features, a farmhouse and a rocky outcrop, seem to be aligned at 120 degrees azimuth when studying photos on Google Earth. The crop tramlines could be aligned at 30 degrees azimuth. The crop circle itself seems to be aligned 7-10 degrees off the tramlines, or close to 20-23 degrees east of north.  

An upcoming solar eclipse on August 1, 2008 in northern Russia  

An upcoming solar eclipse on August 1, 2008 will be seen first over northern Russia near latitude 70 N. Sunrise there on August 1 will be observed at 20-22 degrees east of north (see http://aa.usno.navy.mil/data/docs/AltAz.php): 

Maximum eclipse will be seen at 10:21 UT a few degrees further south, near latitude 65 N and longitude 72 W close to Nyda 
(see http://eclipse.gsfc.nasa.gov/SEmono/TSE2008/TSE2008.html). Sunrise at 65 N on that day will be seen at azimuth 40 degrees, 69 N at 27 degrees, 70 N at 22 degrees, or 71 N at 13 degrees. Above latitude 72 N on August 1, the Sun will not set.  

The approximate field alignment of 20-23 degrees for Furze Knoll seems to match well a far-northern sunrise at latitude 70 N on August 1, the day of our next total solar eclipse: 

In other words, the field alignment of Furze Knoll was seemingly meant to tell us:  

"Your Sun and Moon will line up on Earth's horizon at 20 degrees east of north, for sunrise on August 1 during an upcoming solar eclipse."  

Lizzano, Italy of June 12, 2008 showed the same field alignment as Furze Knoll .

An entirely different solar-eclipse crop picture appeared near Lizzano, Italy on June 12, 2008 (see www.cropcircleconnector.com/inter2008/italy/Lizzano/Lizzano2008a.html). Yet it was likewise aligned to match August 1 sunrise at 70 N:  

The 18-year Saros cycle of eclipses 

Also shown at Furze Knoll was a more subtle feature relating to the long-term nature of eclipses. Thus its large circle for "Earth" showed 18 smaller mini-circles, that were apparently meant to represent a Saros eclipse cycle of 18 years (see http://eclipse.gsfc.nasa.gov/SEsaros/SEsaros.html):
