Candidates Analysis

(1) Use blinking image to see if the object only appears on one of the images.
(2) Use zoomed image to analyze brightness of the object. Is it too faint to see the endpoints?
(3) Use dark zoomed image to find out if the object is a cosmic ray. Is it pixelated?

The common observer's comments are listed below with examples.

Observer's comment: STRONG FMO

Real FMO! Positions sent to MPC. Watch NEO Confirmation Page.

Observer's comment: PIXELATION

The zoomed image shows this is not real due to strong pixelation and/or high contrast with background (lacks gradual change). With experience, we hope reviewers will avoid resubmitting these candidates.

Observer's comment: TOO LONG

Object could be a satellite, diffraction spike, meteor, charge bleed, CCD crosstalk or even a real fmo. But, as it crosses the edge of the blinking edge it is MUCH too fast to recover even if real! Please do not submit these objects.

Observer's comment: STATIONARY

The object in the center is not moving between passes (see blinking image) and there is no other obvious trail in the image. Please avoid resubmitting stationary objects.

Observer's comment: TOO FAINT

If a trail cannot be easily distinguished in the zoomed image, please do not resubmit the candidate. It is probably just noise that the compression turns into a line but even if it is real, it is too faint

Observer's comment: CLOUDS

Conditions are poor (star extinction). FMOs are unlikely to be visible under these conditions.
