Red dwarf binary system, located 11.7 light years from the Sun. Brightest
star is of mag +8.1 with companion star of mag +10.9. Separation measured
as 35 arc secs at PA 65 deg. WDS GRB 34 has a proper motion of 2.89 arc secs/year
(I hope to record this motion with an image taken in 3-5 years time).
Groombridge 34 AB are both flare stars, like UV Ceti . UV Ceti is an extreme
example of a flare star that can boost its brightness by five times in less than
a minute, then fall somewhat slower back down to normal luminosity within two or
three minutes before flaring suddenly again after several hours.

Gamma Draconis was the star that the English physicist Robert Hooke made the first 'modern' attempt to detect annual parallax in 1669. His attempt was unsuccessful, and it was not until the 1830's/1840 that Friedrich Wilhelm Bessel and other astronomers first correctly detected parallax using slightly closer stars (eg 61 Cygni). The star is probably too far away for it to show a parallax that can be measured using amateur equipment. However to check this a baseline astrometric measurement of Gamma Draconis' position was made. This task was made difficult as the number of catalog stars directly around the star is limited. To achieve an adequate plate solution the star was moved to one corner of CCD field of view.
