Charts of variable stars
We have prepared charts with V-magnitude sequences for a number of variable
stars, mainly cataclysmic variables (novae and dwarf novae). These charts
are chiefly based on Hipparcos, Tycho, Guide Star and USNO catalogues, plus
CCD measurements by A. Henden.
1903+12 Nova Aquilae 1999
Field 5 degrees and limiting magnitude 9.5. Available as
GIF and
PostScript files. Chart and magnitudes from Tycho catalogue.
Field 2.5 degrees and limiting magnitude 10.5. Available as
GIF and
PostScript files. Chart and magnitudes from Tycho catalogue.
Field 1.25 degrees and limiting magnitude 11. Available as
GIF and
PostScript files. Chart and magnitudes from Tycho catalogue.
1040-51 V382 Velorum (Nova 1999)
Field 20 degrees and limiting magnitude 7.5. Available as
GIF and
PostScript files. Chart and sequence from Hipparcos catalogue.
Field 5 degrees and limiting magnitude 9. Available as
GIF and
PostScript files. Chart and magnitudes from Tycho catalogue.
Field 2.5 degrees and limiting magnitude 10. Available as
GIF and
PostScript files. Chart and magnitudes from Tycho catalogue.
Field 1.25 degrees and limiting magnitude 11. Available as
GIF and
PostScript files. Chart and magnitudes from Tycho catalogue.
1801-27 Nova Sagittarii 1999
Field 150' and limiting magnitude 10.5. Available as
GIF and
PostScript files. Chart and sequence from Tycho catalogue.
V magnitudes of comparison stars are given in units of 0.01 mag.

0846+58 BZ Ursae Majoris
Field 45' and limiting magnitude ~14.5. Available as
GIF and
PostScript files. Dotted coordinate grid for every 20s of RA and 5'

of Decl. (equinox 2000.0). Last revision 1999 March 27.
Robert Modic has prepared a V-magnitude sequence
[vsnet 1791] which is based on Tycho catalogue and CCD observations by
A. Henden.
