Hoeven Snow Formation #1 (December 19, 2009): 
© Roy BoschmanThe largest (60m x 52m overall dimensions) formation yet reported in snow,
occurred near Hoeven: 21 simple rings, 1 tiny circle & 1 spiraled circle.
At around 11:30pm (Netherlands time) on the evening of December 17, 2009 I called my friend Robbert van den Broeke in Hoeven, and we talked until about 1:30 - 2:00 am (Netherlands time) about various things. Near the end of our conversation Robbert said he felt that some circles might be coming and I got the feeling that this was likely to occur before Christmas.
The next evening (Friday, Dec. 18th) at around midnight Robbert got a very strong feeling that a formation was arriving at the field not too far from his home which we call the "special" field (because so many anomalous events have occurred there over the years). He telephoned a local friend, Ellen Gomis, to ask if she would drive him to the field to see if a new circle was present, and Mrs. Gomis agreed. The temperature was about -10 degrees C and there was a 6-inch snow cover already on the ground.
When they arrived at the field around 1:00 am (now Saturday, Dec. 19th) Robbert immediately felt what he described to me as a peaceful, very still, "holy" feeling and heard what he could only describe as sounding like a choir of "angels singing" in the air above the field. I asked if Ellen heard this, too, but Robbert said "no" -- it was only he who heard the "singing." As they walked down from the dike they could both see multiple rings scooped out of the snow-covered field.
