To obtain the data files which you seek, connect via FTP to the site specified below and follow the additional instructions provided. The examples shown here are valid for a typical UNIX operating system.

FTP Address :

           >   ftp ftp.hao.ucar.edu 122
 
     login >   anonymous
 
  password >   your_email_address

All directories contain an INDEX and README file. README explains the purpose of the directory. The INDEX file lists the names and a brief description of the files in that directory.

SMM C/P Event Images :

A selection of CME images from approximately 40 events recorded by the Solar Maximum Mission (SMM) Coronagraph are available at this time.

To get the SMM C/P event images type :

	ftp>  cd /d5/events/smm/cme	
	ftp>  ls

You will see the following :

	INDEX		Directory contents file
	README		Information file
	gif		GIF images
	jpg		JPEG images
	log		CME catalogues
	ps		Postscript images
	tif		Tiff images

The CME images are available in either GIF, JPEG or TIFF format. If you wish to access GIF images, type: ftp> cd gif If you wish to access JPEG images, type: ftp> cd jpg If you wish to access TIFF images, type: ftp> cd tif Each of the GIF, JPG and TIF directories contain sub-directories, one for each year during which event observations are available. Choose the desired year by moving into the appropriate sub-directory. For instance, to select the 1980 sub-directory, type:

	ftp>  cd 1980

Before you transfer images, set the binary option in FTP by typing:

	ftp>  binary 
	

To transfer one image at a time type:

	ftp>  get filename	 


To transfer all images in the directory type:

	ftp>  mget *

If you wish to obtain mass ejection data that is not yet posted to this directory, please email your request to: mlso_data_requests@ucar.edu)

SMM C/P CME CATALOGS:

        ftp>  cd /d5/events/smm/cme/log

The files containing SMM C/P CME information are:

	smmcp_cme_catalog_1980.ps
	smmcp_cme_catalog_1984.ps
	smmcp_cme_catalog_1985.ps
	smmcp_cme_catalog_1986.ps
	smmcp_cme_catalog_1987.ps
	smmcp_cme_catalog_1988.ps
	smmcp_cme_catalog_ 1989.ps

These images are in Postscript format.

Before you transfer any files, set the binary option in FTP by typing:

	ftp>  binary		 


To transfer one image at a time type:

	ftp>  get filename	 


To transfer all of the catalogue files in the directory, type:

	ftp>  mget *.ps

SMM C/P SYNOPTIC MAPS:

        ftp>  cd /d5/events/smm/syn

The GIF files containing SMM C/P MAPS are organized into separate directories for each year:

For instance, to select the 1980 sub-directory, type:

	ftp>  cd 1980

Before you transfer synoptic map images,
set the binary option in FTP by typing:

	ftp>  binary 
	

To transfer one image at a time type:

	ftp>  get filename	 


To transfer all images in the directory type:

	ftp>  mget *

The synoptic map filenames contain either a single Carrington rotation number, or a starting and ending rotation numbers, follwed by the radius at which the azimuthal scans were performed. For instance, "r20" is used for a map constructed from a scan at 2.0 solar radii. The other two available heights are 2.8 ("r28") and 3.4 ("r34") solar radii.

The files which contain the phrase "cme" show the position and extent of identified coronal mass ejections.
