A new solar system diagram at Cowdrove Hill on June 18, 2011 suggests that some unknown object will outburst soon near Mars orbit Cowdrove Hill of June 18, 2011 shows our inner solar system of Mercury, Venus, Earth and Mars for a date close to June 20, 2011, along with three images of another unknown object, perhaps a comet, which is scheduled to outburst or explode soon close to Mars orbit. Two accompanying slides show the locations and orbits of Mercury, Venus, Earth and Mars for a date of June 20, along with the positions of two known comets which are located currently near Mars orbit: namely comet C/2011 C1 McNaught or comet C/2010 X1 Elenin. A big "C-shaped" symbol on the left of Cowdrove Hill seems to tell where the unknown object will be located in space. Two other symbols along its outer ring seem to imply an outburst (semi-circle with thin dividing lines) followed by brightness (open circle on the right). These new symbols seem similar to other "outburst" symbols drawn at Sanctuary or Hackpen Hill on May 30, 2011. We used the "Near Earth Object" website to generate planetary and orbital diagrams for two known comets, namely C/2011 C1 or C/2010 X1, yet neither of our candidate comets seems to be located exactly where indicated at Cowdrove Hill by a big "C-shaped" symbol, not far from the current location of Mars: Thus it remains unclear from their most recent drawing at Cowdrove Hill (if real) what exactly might happen soon in space, close to planet Mars and Mars orbit? Yet it should not be long until we find out! A second crop picture from June 18 shows a spiral symbol and three small crescent Moons, suggesting perhaps three days later on June 21? This may be the same astronomical event predicted at Milk Hill in 2009, where some "mystery object" was supposed to suddenly brighten not far from the orbit and location of Mars in June of 2011, after a five-planet alignment in early June. Now we can only wait and see. Red Collie (Dr. Horace R. Drew) in Hong Kong, headed for Wiltshire Does the outer ring at Cowdrove Hill show a time series of astronomical events for the near future, based on four inner planets which specify a date close to June 21, 2011? Four inner rings at Cowdrove Hill seem to show the current locations of Mercury, Venus, Earth and Mars ("reversed C") for a date close to June 21, 2011. Yet what might those strange symbols along its outer ring signify? If we consider that its outer ring may show a series of astronomical events through time, then we can assign four discrete locations along that ring going clockwise as 0 (reversed C), 1 (blank space), 2 (nested thin lines) or 3 (large open circle). Next if we compare to a true astronomical diagram as shown below, we can see planet Mars at position 0 on the left, or comet C/2011 C1 (small blue dot) at position 1 on upper left: Several thin nested lines at position 2 would lie just above planet Earth in the diagram shown above, at upper right, while a large open circle at position 3 would lie to the far right of Mercury at middle right. Could this be a "missing comet" diagram, analogous to Longwood Warren 1995, which predicted the location in space of an outburst by comet 73P using a "missing Earth" symbol? If the current location of comet C/2011 C1 (small blue dot) is being represented by a "blank space" in the new crop picture, along its outer ring at position 1 (upper left), then the complete clockwise time series 1-2-3 could symbolize an outburst in the near future.
