WEBCAM July 2018
#1
Post webcam observations for July here.  Observations should start with a date and ‘jst’ time (Japan Standard Time) and camera(s).  Describe as best as possible what you see.  Contribute data such as weather conditions, work activities, TEPCO or local news reports, radiation readings, earthquake activity, or any information that documents events occurring at Daiichi.  Comments and analysis welcome.  Help keep an eye on TEPCO's disaster site.

More remote cranes surround r1 and they've been working late.  There's been a noticable increase in the activity around r1, I wonder what's going on.  What brought me to this evenings recording was that odd little light transiting the upper left hand corner of cam1.  I haven't been able to watch much or skim thru recordings lately, just been busy with other chores.  I could use some help at watching the cams.  I haven't checked if it happens every night now; it was only by chance I noticed it again.  No moon or moonlit sea this time.  The light didn't have a crane in the way.  The color seemed to pulse white or pale to a deep orange but it was on steady. The event lasts 25 minutes.  The combo pics are 3 minutes apart except where I included the distortion, spider movement, and sparks.

The week was full of foggy conditions.  Fog developed during the day and at night, sometimes just a layer over the buildings up to a complete grey out of the screen.  The fog was sometimes localized showing on one camera before engulfing both cameras.  I noticed cam1 had gone black and white so I looked for the filter change hoping to catch a camera resetting.  The change was abrupt, no zoom outs.  The camera reset back to color later in the light of day.  Watching the fog roll in and out I still see the thickest fog developing over r2 and the CSFP area.  A spider crawled across the screen.  I didn't see any crane activities in the brief periods of clearing to report, just a busy spider working hard in front of cam1.  I noticed a lot of sparking and started to count.   22 sparks in an hour.

7 July, Microcarpa said this about Fukushima during recent rains (western Japan).

"Flooding in west #Japan has no effect on #Fukushima, 'cause it's too far away. Rainy and seasonal cold & humid wind called "Yamase" may cause dense fog surrounding Dai-ichi.Making it look like radioactive plume,but it's just a fog(or partly not?)"

just pm me if needed.

I understand that Daiichi gets dense fog this time of year naturally.  I also know that radionuclides promote fog formation.  From the camera views I can't really measure how dense the fog is.  Sometimes it looks thicker or it seems to linger longer over certain parts of the plant but that is a subjective observation.  Once fog engulfs the cameras the view becomes very limited.  Whether foggy or clear the sparking on the cameras can be a measure of the gamma radiation in the air around the cameras at the north and south ends of the plant providing a more objective observation.  The sparks are indicating that the fog over Daiichi sometimes shows more radioactivity than at other times.  

07-08 More foggy pictures; the camera views at dawn to show the pink in the sky and the morning and noon shots to show how different the weather conditions can be from the north end to the south end of the plant.

The fog comes and goes, often several times in a day or night, on one camera or the other but most often on both.  To be clear, I don't think the fog is a new radioactive plume.  I think the spark activity in the fog is just fallout of the emissions over the plant.  The small increase of sparks I saw could have been because of the added burden from the recent opening of r2.  

07-09  The fog cleared for a bit and I saw that light transiting in the upper left hand corner of cam1 again.  

   
   

I wasn't scanning for sparks but when I skipped thru the recording I landed on a green spark.  In the spark pic, if you look between r1 and r2 there is a moon lit glow in the water.  The moon must have passed by earlier when it was still foggy.
