Various types of flare information, activity, active region reports, x-ray plots and
daily Campaign Action notices are now available on SPAN, and INTERNET. Although
this system was developed for use of Max '91 participants during campains, it is updated
daily and maintained at times outside of campaigns. Thus it is available for general use
outside of campaigns.
The Space Environment Laboratory maintains VAX and Apollo systems, both of
which are on INTERNET. The VAX is also on the SPAN network as node SELVAX or
9555. Details of access to files on the VAX are given below.
I. Types of Information
The following types of information are available in conveniently labeled files on the
VAX and Apollo systems.
* Daily Event Listing_
Single line listings of solar flares compiled at 03:00 UT for the previous day. These files are
composed in near-real-time by forecasters at NOAA's Space Environment Laboratory. As-
sociations of optical and X-ray events are generally established through time coincidences
of GOES data with optical identifications provided by the U.S. Air Force SOON network.
* Solar Foreca_t_
Probabilities of flare production for the sun as a whole, activity summaries and geomagnetic
forecasts.
* Solar Activity Reports
Listings of significant activity from various regions as well as particle events and recent
geomagnetic activity.
* Region Reports
Descriptions of various active regions including positions, areas and spot, classifications and
announcements of returning regions.

* Plots of GOES soft X-rays with tagged optical events
Since Textronix emulation is available for almost all computers, Textronix 4010 compat-
ible plot files which show the GOES hard and soft channels in standard 6-hour plots are
available. There are four plots per day generated at 3:00 UT for the previous day. The
files may be copied or plotted directly over the networks.
* Campaign Action
Perhaps the most important information to be distributed during campaigns (and the only
daily information which that is directly distributed to participants via EMAIL) are the
daily Campaign Action notices. These bulletins will contain daily target information, sta-
tus of primary instruments, observing itineraries, solar activity reports and brief reminders
of scientific objectives. The distribution will be primarily through electronic mail and the
GEOALERTS. Action notices are also saved in files as described below, thus if the mes-
sage is not delivered promptly, then the participant should be able to retrieve the daily
ACTION notice in the same manner as the other types of data.
II. SPAN Access to MAX '91 Information and Action Notices (VAX VMS)
On the SPAN network, node SELVAX:: or 9555:: has available a variety of files
with various types of information as shown in Table I.
To receive Max '91 information files over SPAN (VAX VMS) one should type:
SET DEFAULT 9555::sys$userroot:[max91]
Entering a command such as
TYPE 21JUN89.EVENTS
will display the event listing for June 21st on the display. One may also type DIR to
list the files that are available. Note that the complete file description with node can be
specified in the TYPE statement without setting the default directory but this may be
cumbersome if more than one file is accessed.
GOES Soft X-Ray Plots
(for TEXTRONIX-4010 compatible terminals and printers)
The SPAN Node 9555:: also has copies of GOES plots - Textronix files that are
available at 9:00 UT for the previous day. A Textronix 4010 terminal or an equivalent
emulation is required. On SPAN to receive a plot type:
TYPE 9555::SYS$USERROOT:[MAX91]08JUN89A.SAV (You may also COPY it
to your directory)

You will receive a 6-hour GOES plot 0:00 - 6:00 UT for 08 Jun 89 as the name
suggests. The suffixes A,B,C or D in the file name indicates 0-6, 6-12, 12-18 and 18-24
UT, respectively, for the day described in the file name. The data in the upper and lower
curves represent one minute averages of the 1-8A and 0.5-4A data respectively. To provide
the most complete soft x-ray coverage (in case of losses of data) data from both the GOES-
6 and GOES-7 sattelites are presented. Data from GOES-6 is drawn as a dotted line while
data from GOES-7 (the primary sattelite) is drawn as a solid line.
IMPORTANT NOTE: ON VAX VMS SYSTEMS: for plots to work be sure that yotu
terminal is set to NOWRAP. If it is not, then issue the command: SET TERM/NOWRAP
62
(Note that data more than 1 month old will be deleted from the disk in order to
conserve disk space.)
Additional means of receiving the Daily Action Notices (during campaigns only)
A backup communications system for SELVAX:: has been established on the node
SOLARX:: at the University of Colorado. Only the daily ACTION notices are stored on
this account and they may be accessed by entering commands like:
TYPE SOLARX::UP:[MAX91123JUN89.ACTION
Note also that a third method of receiving the action notices is to send any mail
message to the solarmail address - SOLAR::maxaction. In this case, a mail message con-
taining the current action notice will be transmitted back to requesting party in most
instances.
III. INTERNET Access using TELNET and FTP
* TELNET access
By far the easiest way to access Max '91 information over INTERNET is to log onto
SELVAX directly and to access the files as described above for SPAN. It is also possible
to copy the files to your computer by using FTP as described at the end of this section.
For TELNET access to SELVAX type:
telnet 132.163.2_.10
When the system prompts for the USERNAME:, type MAXT (a mnemonic for
Max' 91 and TELNET). No password is needed. Typing the various files as described for
SPAN will bring the reports and plots to your screen. To terminate the connection type
LOGOFF.
Note that this is a very restricted account and it cannot be used to connect to
SPAN or access other directories on SELVAX. It is not intended for SPAN users to use the
MAXT account since SET DEFAULT as described above accomplishes the same results.
* FTP access
(The following assumes that anyone on INTERNET has FTP file transfer protocol
available.)
INTERNET access to NOAA's SELVAX computer to acquire the Max '91 event
listings, region reports, goes plots etc. is available.
63
To your system type the numeric address (lower case recommended): (On some
systems the name address: _elvaz.bldr.nist.gov may be required instead of the numeric
address.)
ftp ISg.16S.224.10
The system should respond with a USER: request. If it does request a username,
type- ftp.
If a password is requested, simply type a carriage return since no password is re-
quired.
You then should have FTP access to SELVAX.
One should type: cd [maz91] or perhaps cd maz91 ; to change defaults to the proper
directory.
If your system fails to accept this you might try going to a higher level by:
ftp> cd .. ftp> cd max91
One of these steps should put you on the proper directory. Entering "dir" or "ls"
or a similar command should provide a list of the files that are available. One can then
"get" files from SELVAX as you desire since the SELVAX MAX91 account is open to file
outgoing file transfers. (Note to transfer GOES plots one should type "binary" before the
"get" command so as to correctly transfer the file.)
eg.: ftp> binary ; sets file transfer mode
ftp> get 25jun89a.sav ; should bring plot the file to your system
With the exception of the ACTION notices that are only issued during campaigns,
the remainder of information described above is planned to be available on a continuous
basis throughout the Max '91 program. Thus observatories can receive GOES plots or
region summaries at anytime desired. However, due to a limited amount of disk space on
SELVAX, some files may only be retained for one or two weeks. Campaign data will reside
on the disk longer than files that are generated outside of campaigns.
