Subject: URGENT: BK 121 = VLBA, Y1 ToO for SGR 1806-20 on Jan 5 UT

Mike:  We have accepted this ToO proposal (cover sheet attached) for 
two segments.

Segment A will be on January 5, 1400-2200 UT, with a VLA single antenna, 
at 256 Mbits/sec but limited to one tape per station.  Becasue this 
observation involves a maintainance day at the VLA, the single VLA 
antenna will participate on a best-effort basis. 

Please ftp your schedule files to aspen via

      cd astronomy/jan05/bk121a

and be sure to cc vlbaops and vlaops when you have done so.  Your 
observation nominally starts about 7am in New Mexico, when the trusty
VLA and VLBA operators will be the only staff on duty.

I am herewith asking Lorant Sjouwerman to serve as local technical
contact person for this ToO proposal.

I will email you tomorrow concerning Segment B.

Mike:

Your last ToO observation, segment B, will be on January 6 UT.

Because segment B is a short observation that is related to the ToO
allocation to AK 598, we ask that you schedule segment B with LST =
VLA and day = 60094.  You will have the VLBA without Pie Town for
1800-1900 LST, then the VLBA with Pie Town and a single VLA antenna
for 1900-2100 LST.  The recording rate will be 256 Mbits/sec.

Please ftp your schedule files to aspen (cd astronomy/jan05/bk121b)
ASAP, so Operations can learn your specific UTs.

Lorant Sjouwerman will serve as local technical contact person for
this ToO proposal.

- Joan

Hello Mike and all,

We were able to get the VLBA schedule and get set up before the start
of our VLBA observing schedule, BUT then we were shut down for
high winds.  At 18:32 UT we were back on source.  We
also were able to setup the GBT Spigot to observe simultaneously.

The Normal GBT VLBA setup calls for a band pass filter in
the range 1.3 to 1.45 GHz.  So this strongly limits the
detectable signal in the 0.8 GHz Pulsar spigot mode used for
the piggy back operations.  The Spigot observations
running at 18:36 UT
