Both of those features suggest that a solar storm may impact Earth on July 7, 2009, as has already been suggested by several other crop pictures from April or May (see bishopcannings or roundway2).
The new crop picture also shows a small, horizontal, four-circle band just between its head and its long tail (blue arrows, left or right above). That feature closely resembles a crop picture from July 20, 2008 which told us about eclipses (see time2007x). Indeed, the suggested date of July 7, 2009 for an upcoming solar storm will be a penumbral lunar eclipse (see eclipse.gsfc.nasa.gov).
“If directed at Earth, a coronal mass ejection is harmless to people, but slams into Earth's magnetic field, thereby distorting it into the shape of a jellyfish buffeted by a strong current. The most severe CMEs may cause geomagnetic storms capable of disrupting satellites, radio communications or power systems†(see
