Kind of off topic, but does anyone know if the left and right front hazcams actually take their respective stereo images at exactly the same time? The time stamps usually appear as identical with left and right pairs, but is their a slight difference in the actual imaging time of a few milliseconds? I ask because while scrolling through the 14 images taken on Sol 276 (the entire sequence is here), I noticed a bright "smear" in the sky above Mt. Sharp that appears only on one particular right hazcam image of the sequence. The corresponding left image, lacks this anomaly, as well as all the others in the sequence. The JPL raw image page time stamps both left and right images at "2013-05-16 16:45:59 UTC"
Is this a processing anomaly or a lens glint? If it's a glint then from what? The cameras appear to be in full shadow. Upon closer inspection it seems to almost have a "nucleus" of sorts, (one very bright pixel) and even a wispy looking "tail" associated with it. It certainly seems highly improbable this could be daytime meteor trail, but it almost has that kind of look. If the hazcams take their frames at precisely the same moment then of course it's not or it'd appear on the left image too, correct? . Just wondering what might have caused this because I don't recall seeing many distinct single frame hazcam anomalies (like this one anyway) very often, and it doesn't have a 'digital glitch' look at all due it's wispy nature. Most likely a sun-dog on the lens then? Caused by what though? A reflection off the turret? ... same image with levels tweaked to bring out details: -------------------- "We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time." -T.S.
