The biggest was April 3, 1947...

Hmmm, just a few months later was the Roswell incident July 1947

[Mister Obvious]

Yeah, I was thinking about WW2. It didn't dawn on me that Roswell happened around that time, but I knew there was something significant about those years.

Here is a view of the full solar disk during a two-week period in October and November of 2003 which exhibited some of the largest solar activity events since the advent of space-based solar observing.

Iconic 2003 solar flares...

This is still my fave solar flare pic of all time though...

CMEs are the greatest thing ever.

The only time I care to see snow is on the LASCO C2...

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:

1. 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.

2. 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.

Lookin' good.

This is a really cool page.

We've really stepped up our real time monitoring of Sol's activity over the years!?

Kind of ashamed to say I've never even explored this site before...

They even have the corresponding photo of the CME beside each listing...

Wow, I'm gonna have to make it a point to look at this daily.

[Mister Obvious]

I usually just go to the SDO/NASA site instead. Or SpaceWeather.com.
