JunoCam makes images from wideangle scans of the clouds directly below the spacecraft, which swoops close in, 3,500 km in altitude, at each perijove. So targets can be selected by latitude but not by longitude, because the location of a particular candidate "spot" depends on its often-variable drift in longitude.
Also, because JunoCam views the planet at such close range, it is important to put its images into a wider context using amateur images of the track taken close to the time of perijove. Several observers have made special efforts to obtain these, notably Clyde Foster in South Africa.

Three and a half months after perijove, Galileo reaches the farthest point in its initial orbit (apojove).
Chodas (Jet Propulsion Laboratory) argue that a 9- or 10-km body must have come apart 2 1/2 hours after its perijove
in 1992, a scenario they feel is required by the length and orientation of the fragment train.
According to this orbital solution, the cometary fragments have at least a 99 percent chance of crashing into Jupiter at their next closest approach, or perijove
. But for all its drama we'll miss seeing the spectacle, at least directly.
