[McIDAS #HUK-605825]: GOES-east Outage

Hi Fred,

> Tuesday evening at 3:30Z the GOES-13 failed because of a problem with its star
> tracker.  NESDIS is still trouble shooting the problem on GOES-13, but does 
> not
> have any quick fix.  NESDIS has activated GOES-14 located at 105W which is now
> routinely providing satellite data.  However, no decision has been made on the
> fate of GOES-13 or moving GOES-14 into the operational east position at 75W.
> While GOES-14 is transmitting data, the data is not being routed through GOES-
> 13.

The non-routing of GOES-14 data through GOES-13 was quite a surprise to me.
It either means that GOES-13 is in BIG trouble (e.g., transponders not
working or causing too big of a drain on power), or that NESDIS is hoping
to get things working again.

> NESDIS has stated that any GVAR users with antennas who want current data

I saw this while checking my email in the airport in Houston.

I will be interacting with folks in the office tomorrow to see if they are
up for re-pointing the GOES-East dish to the 105 W longitude slot.  If the 
strength is high enough, the LNB should not have to be rotated to correct for
the polarity alignment that a simple swing of the antenna will cause.  The
problem is that I am typically one of two at Unidata that does things like this,
and I will not be back in Boulder until June 10.

Personally, I am up for re-pointing our GOES-East dish now, and swinging it
eastward if/when GOES-14 is drifted to the GOES-East slot.  I'll know more
tomorrow, however.
