Objects Session Notes
WDS GRB 34 - Double Star NSV 13395 - Possible Variable Star Tumbling Satellite ?
- 1.5 hour session - Aim of session was to record a variety of starfields in Cygnus with NSV (suspected variables), to enable testing of software to detect variable star behaviour - Opportunity was taken to record the nearby red dwarf binary star system WDS GRB 34) - More Notes
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.
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).

| Tumbling Satellite ? or Plane ? (Notice how track seems to wobble. This may not be real phenomena of the moving object, but may be due instead to periodic error on the telescope's RA drive, or is related to atmospheric turbulence (seeing) |
