I would say it's a huge interstellar mothership, caught in the moment of exploison, being overloaded on to much helium it took few moments ago,

I think defcon5 is correct. IIRC, the answer will include "telemetry dropout".
I'm about 99.9% certain that's Venus on the right. The white lines are CCD blooming.
Here's another example of the dropout.
The LASCO instruments are not the newest. They were built in the late 1980s, when a digital camera was something very special. Sometimes disturbances do happen.
There are two kinds that repeatedly occur:
Blackouts and Whiteouts, in broken lines, circle-like shapes, or over the whole picture. They are caused by the electronics box. There has never been a firmware update, since it was judged as too sensitive changing the flight-software.
Black and white pixels, occurring in patterns, without pattern or alone. Those "missing blocks" are telemetry dropouts, caused by radio interference or a disturbance in the data transfer to Goddard Space Flight Center.
Simple answer: crapy software!
The software uses a circular buffer, and instead of nulling old images just overwrites them with new images once they become available. If there is a data gap, the old images remain in the buffer instead of being deleted. If the next DSN pass includes data from the onboard tape recorder (which can be several weeks old), the software sometimes gets confused and associates the header with a wrong image file.
I should emphasize that this affects only the quicklook data (quick and dirty near real-time data that are created on the fly for our web pages). The final level 0 science quality data in the SOHO science archive are correct.
