Select November 21, and it takes us here:

We can select data from any hour of the day, in this case he used
the 1500 UTC hour:

Here we see a mind-boggling trove of data.  The particular one he
sent was the Global Plot from 1533 UTC. There are also north and
south pole plots. You can see these minute-by-minute if you want,
stepping forward and back in time.

Here is a list of A and K index readings for the third quarter of
2012:

Note the high numbers on July 15, 2012. It looks like the highest K
index values were at the 0600 and 0900 UTC readings.

At 0639 UTC, you can see a big effect:

This looks like an interesting tool for examining some of the
effects of solar flares.

John Dyckman, WA3KFT of Aston, Pennsylvania is on a local 10 meter
SSB net which meets daily at 1800-1900 UTC (actually 1-2:00 PM local
time) on 28.435 MHz. On November 26 he and other stations on the net
worked WA7DUH in Washington, KD0TBB, WB0Y and KD0QCF in Colorado,
N3AAW in Montana and ZS6JPY in South Africa. 10 meters seemed open
to the world, and signals were from S7 to 10 dB over S9 for the
whole hour. So even with the somewhat depressed solar activity, 10
meters is still alive.
