Such a scenario dovetailed neatly with the old speculations that Phobos is actually an artificial satellite of Mars, which is being used as a base of operations by someone or something.
All surface detail is washed out, as is common in infrared photographs.
If the PMO was at the same distance as Phobos itself, it would be about 2 kilometers wide and 20 long. Its surface brightness is the same as that of Phobos. Since the PMO does not appear to have a metallic surface and displays no antennas or other indicators of artificiality, it is reasonable to ask whether it might be some natural phenomenon. Since the exposure time of the last photo was 8 seconds, a smeared image due to the PMO's relative motion is reasonable. This new newsletter, edited by astronomer T. Van Flandern, focusses on astronomical anomalies.
