I was sky watching last night when i looked at a stationary oval-shaped object that looked too big and too bright to be a planet begin moving from south to north in a straight-line path. the color was a brilliant white. i thought "i wonder if that is a ufo?" when it flared up to 10 times its original size and disappeared completely. i thought it might have been a satellite, but after it flared up or exploded it was no longer there. i watched it for about two minutes. i kept watching for another five minutes to see if it would reappear and continue on its trajectory but it did not. i have seen several ufos in this same area over west independence in the last few years.
