If I have the time I may check the alternate angle on the high speed replay. I might catch one.

I think the reason we have not seen more cross checked, Unit1 Cam vs Unit4 Cam, is because most people might not think to do it, take the time to do it or have the knowledge to do it.
I also know the TEPCO cam clocks are not synced.
Currently they are off by about 45 seconds which is the difference on the double spark multi-angle shot.
I have cross checked many times and never seen one like the other night's double catch. Although, I have always thought it probable, as a way to possibly verify Theory 1. I'll be checking more now.
Distance and angles are hard to determine with these zoomed cams.
The purple spark on the smoke stack screenshot is interesting. (2016-07-22 23:18:35) If an Aerial Spark, then it is between the stack and the camera. It would be great to catch a 'longy' spark that is partially blocked by a stack or crane. That might tell us something.
Did your screenshots come from the high speed recording or from your own recording?
Hi Chasaha, I’m glad the two sets of well timed sparks stirred a little excitement. Since you first raised the ‘aerial’ theory, I have been cross-checking when I find a c4 spark. I’ll admit to a bit of surprise at finally finding two matchups. The spark grabs come from scanning my recordings. I sometimes go thru the time lapse vids and have grabbed from there but it’s much more difficult, kudos to those with the patience. I encourage anyone spotting a suspected c4 spark to post a jst time so we can cross check. I say suspected c4 spark because most of the ones I note down to check aren’t really there; my old eyes get tricked by the flash of a neon light. The sparks flash by so quickly watching in real time and I’m never sure if I really saw one until I check the recording.
“purple spark on the smoke stack screenshot is interesting. (2016-07-22 23:18:35)”
I have not found a spark that is partially blocked by cranes or tower. They all appear closer to the lens, in front of objects. The ones on the r1 tent are obviously between the camera and the reactor building. It’s been strong evidence for a CCD effect. However, I have noticed that Fuku fogging seems to dim the sparks. We also need to come up with a mechanism for an aerial effect. Something exploding in the distance wouldn’t be a pinpoint spark. The closest I can get would be a comparison to fireworks, sparks from igniting metal particles.
Here’s a funny, most of the sparks I noticed before I started recording the tepcams I saw on cam4. That was when r3 sfp was having debris removed and r4 spent fuel was said to be removed and the common pool was much hotter than now. In the early days, sparks were hardly mentioned and everyone was fascinated by webs. What did the old-timers think of the sparks? Nuckelchen pointed out the distortions, but that didn’t get much traction. When I see sparks on cam4 I think of something on the south side, like r3 sfp. Cam4 doesn’t spark as much as it used to. When the roof came off of r1 the sparking on cam1 increased. The radiation in the air near the cameras make sparks flash in the view. I have no problem with both theories being correct; I think we’re just figuring out the details. The switch to flowplayer put color into most of the sparks, and changed the colors; red now looks orange. I think they adjusted the f-stop or exposure time on the cam feeds.
Majia and the watchers on the Enenews webcam forum are complaining how difficult connecting to the TEPCO Flowplayer feeds is and they get rather alarmist. I haven’t had any problems with maintaining connection to the tepcams. Even the early morning disconnects have stopped. Flowplayer is more demanding of video and browsers are more demanding of computer memory resources than the old direct feeds were. Clean your computer or consider equipment upgrades.
“I also know the TEPCO cam clocks are not synced.

Yes, so which one syncs to official jst time? Been meaning to check, is either one the real jst or are both delayed?
Thanks Chas for debating the true nature of sparks, I might not have looked or known what to look for without your input and it helps me to stay objective.
