Very bright light. appeared to be a helicopter at first except there were no flashing lights. moved slowly through sky from south west toward the east at 7:15-7:20pm sept 24. watched as light moved east. intensity of light stayed consistent. last 5 seconds it dimmed quickly and was no longer visible. faded as it passed into the shadow from the earth. it appeared to move slowly in the sky… so either very large and far away or close, slow moving and very reflective. light faded at around 20 degrees in sky just after sunset in hesperia ca.
