what appears to be bright planet disappears in the Northern sky over N Central OK 02/21/0902/21/2009 approx. 23:19 pm /central standard time--N Central OKSee large bright planet in the western sky. It’s been there recently during the past week. Looking North at about 45 degrees see another bright light which seems stationary, but disappears after 3-5 seconds. Not spotted anywhere else in sky. (It was not quite as large as planet in the west, but close in size. Quite bright. Do satellites just blink out that way? Witnessed by myself and husband.
