I did not witness the event in person. i discovered a strange greenish object on our company webcam located in malcesine, italy facing westwards. and also 2 strange strips with dots which i believe must be an airplane but i am not sure about that. the camera takes a shot every 10 minutes during night with a exposure time of 15sec. the image was taken on the 3rd of april 2017 at 21:40 you can find the original image online here: http://www.Addicted-sports.Com/webcam/gardasee/malcesine/#/2017/04/03/2140/exif by clicking the picture you will have the full resolution view. if you then change the time to 23:50 you will see the beginning of a brown object forming until 06:10 in the morning when it suddenly dissapear. there is also youtube video about that picture and his theory is a lens array to hide planet x. you can find this video here: https://www.Youtube.Com/watch?V=oquhrun1tb8 i would appreciate if there is anybody who might have more information about this. i am very curious especially after a good friend told me that she witnessed a sighting at the exact same place in 2008. thank you everybody for your interest and patience.
