The ISS views are incredible. The outages and waiting for the dark periods to hunt for sparks were frustrating. Watching the earth below it was hard to figure out what the ISS was flying over. I just hope that was a desert in the top grab and not a Fuku pink cloud.

A simple explanation would be a loose strand of a real spider web blowing around in front of the camera lens reflecting the bright site lights.  I've seen that once before but it was easily identified by the common anchor points of the web thread.  These bolts of light or streaks emerged from the right side of the screen at various heights and didn't have a single anchor point.  I also noticed that the streaks were occurring when the sparks did and absent when the sparks were absent.  The streak activity increased as the spark activity increased in the hour of recording that I scanned.  I wouldn't hazard a guess yet what those streaks are.  The sparks remind me of a fireworks show and the streaks looked like the smoke from the rockets launching them into the air.  Not very scientific, so I'll point out the streaks are unusual, not mentioned before that I know of.  

With all the earthquake activity I expected more 'fogging' events and I think that radioactive steam coming from the Common Spent Fuel Pool is the source of a large part of that 'fogging'.  Dropping the TBS feed for a week on the camera that gives us a front on view would give Tepco plenty of time to vent the CSFP without showing the dramatic waves of fog rolling across the screen in videos that used to spill out on the internet and stir up chatter in the old webcam forum.  Counting sparks has been faster with the flowplayer only giving us half the data that we had last year.  Doubling the counts for this year to compare to last year indicate conditions are as bad as the worst of last year.

Arrow  [good observation] I also noticed that the streaks were occurring when the sparks did and absent when the sparks were absent.  The streak activity increased as the spark activity increased in the hour of recording that I scanned.  I wouldn't hazard a guess yet what those streaks are.  The sparks remind me of a fireworks show and the streaks looked like the smoke from the rockets launching them into the air.  Not very scientific, so I'll point out the streaks are unusual, not mentioned before that I know of. 
  • Loose strands from a 'spider web' effect was my first thought.  They seemed to whip in the wind.
  • My second thought was a volcano like puffing from a rouge core venting.
  • My third thought is that there is something spewing from the CSFP.  Maybe that's why they have it covered up on the cam 4 side.
Wink  Something goin' on.

At this point - five years+ later, we need to advocate new video/camera infrastructure housed inside most reliable cam protection for radioactive area. I don't know anyone producing such protection for video cams in rad environs. We know that rads bust all so far presented electronic recording equipment, so - testing/data collection is not sufficient after so many years. Electronics get fried no matter current special engineering. What has not been tested for short duration intentioned excursions? Highest quality rad protection required. Space Sci on earth needed. Now.

just pm me if needed.

Well Pia, Tepco needs better radiation hardened robots at the Dai-Ichi disaster site, but the cameras aren't the show stopper.  'Space Sci' CCD cameras onboard the ISS show sparks in high radiation fields; it seems to be a feature of CCD technology.  The Tepco cameras are good quality surveillance cameras with positioning, zoom, and a frame rate of at least 10fps.  Tepco has carefully selected camera angles, diminished the viewing area by zooming in on rooflines to show as little activity as possible and concealed the area of the common spent fuel pool.  This year, the frame rate was reduced to 5fps to conceal or diminish the sparks and emissions that I think are indications of the radioactive steam being released into the air at the site.  

Good news, the ENENews webcam forum is fixed.  Many important observations and links were posted on that network, great to see it working again.

Of course, I ought have known it'd be more an issue of placement and handling.

4-25 a spark count from 20:00 – 20:59 found 16 sparks.  One was a nice double.  

   

A moon transit started about 22:45 and I scanned for sparks.  Found those streaks again and sparks; another double.

TBS/JNN still off-air.   Several weeks now.   Huh

4-27 17:56 on cam1 there was a big spider, possibly an orb spider, swinging in front of the camera.  The streaks seen recently could be from spider webbing.  Aside from the streaks, the spark counts have been fairly high recently and include fancy double sparks.  The remote cranes have been busy during the day.  Much of the work over unit3 must be trying to get the reactor ready for the superstructure that was to be used to remove spent fuel from unit3's sfp.  Hard to believe much could be left in there.  The ice wall is said to be working, slowly freezing the ground around the reactor buildings.  It remains to be seen if freezing the ground will slow the radioactive contamination leaking out to sea.  Tepco recently announced plans to remove the top of the 25 Sievert r1/r2 cooling tower that is falling apart.  Tepco hasn’t mentioned where the tower will end up, hope that doesn't disappear into the harbor or worse yet into car parts.  The TBS/JNN cam is back up this evening but this time of night I see only pixilation.
