[IDV #TNW-894406]: IDV: Lightning data

I can verify that an NLDN record with no lightning flash data was being
sent out every six minutes.  This null record (valid header, no data) was
sent as sort of a heartbeat.  I assume that you were getting those products
and no others.  At least, I didn't see any products with valid/usable data.

re: There will be an announcement after the necessary sign-up web pages have
been updated at Embry Riddle.

> OK, I'll keep an eye out for that.

We are planning on providing an eLetter article and sending an announcement
to appropriate email list(s) (e.g., ldm-users).

Yes, folks are now aware of the return of NLDN data.  There are still issues
being worked through with the data, however.  That's why there has not been
an announcement.

They are share a very large fraction of code in their bases.  Also, things like 
are sharable between systems.

I'm happy to help out when I can...

If the only access available is from local machines, then this is OK.  If, 
is more general, this is definitely _not_ OK as it violates the usage ageements!

I am afraid that "security through obscurity" is not OK in this instance.  You
can configure the NLDN setup in your local RAMADDA to restrict access to the
data.  Please do so as soon as possible!

Yes, there are lots of interesting things going on that can not (yet) be shared
with the community at-large.  To me, this is one of the benefits of being
on one of the governing committees :-)
