Access to On-line Solar Data (1Sep92)
(from NSO, NOAO Newsletter No. 31, 1 September 1992)

This article describes changes that will affect access to files
containing solar data stored on an anonymous FTP disk at NOAO. This
includes the Sac Peak Coronal Maps, Kitt Peak Vacuum Telescope
magnetograms, and various GONG data products.

The VAXcluster at NOAO currently consists of three VMS/VAXen: DRACO,
ROBUR, and VELA. During June or July, the disk containing the NSO's
anonymous FTP disk will be moved from DRACO to VELA. Soon afterwards,
DRACO will be retired from service and the VAXcluster will consist of
ROBUR and VELA.

This equipment change will require both an outage of several days and
an address change for those who access the disk via FTP. (There is no
change of address if accessed via NSI/DECnet, alias SPAN.) However,
since ROBUR is already part of the VAXcluster with DRACO, the new FTP
address can be used to access the disk before the disk is moved. Of
course, after the hardware change the new FTP address will be
required.

The new procedure for accessing the disk via INTERNET using FTP is as
follows:

   host: robur.tuc.noao.edu or 140.252.1.10
   ftp login: anonftp
   ftp password: guest

followed by
   cd gong
 for GONG files or
   cd kpvt
 for Kitt Peak Vacuum Telescope files or
   cd spcm
 for Sac Peak Coronal Maps.

Access via NSI/DECnet (alias SPAN) has not changed:
   noao::ga0:[ftp.gong], or
   5355::ga0:[ftp.gong]
      ;i.e., ga{zero}.

Substitute `kpvt' for `gong' to access the Kitt Peak Vacuum Telescope
files or substitute `spcm' for `gong' to access the Sac Peak Coronal
Maps.

If you have questions regarding these changes or if you encounter
problems trying to access files on the disk, please contact Jim Pintar
(jpintar@solar.stanford.edu, or pintar@noao.edu, or phone 602-325-9272).
