Abstract:
Presentation of a period and light curve for GSC 3948:1963 in Cygnus
Name of the object: GSC 3948:1963
Equatorial coordinates: R.A.= 20h03m04s.3 DEC.= +59°06'54".0 Equinox: 2000
Observatory and telescope: Kitt Peak National Observatory, 0.9m telescope
Detector: T2KA CCD, 2048 × 2048 pixels
Filter(s): B
Date(s) of observation(s): 1998.07.10, 11, 28, 30, 31
Comparison star(s): large ensemble
Check star(s): large ensemble
Transformed to a standard system: No
Availability of the data: upon request
Type of variability: DSCT
Remarks: Period of 0.05589 ±0.00001 days with an amplitude
of about 0.14 ±0.01 mag in B. The descending
branch is steeper than the ascending branch.
Acknowledgements: These observations were made as part of the Research
Experience for Undergraduates (REU) programs at the National Optical
Astronomy Observatories (NOAO) and the National Solar Observatories
(NSO), both of which were funded by the National Science Foundation.
We would like to thank Dr. Nigel Sharp of NOAO, and the participants
of the 1998 NOAO and NSO REU programs for their help with the
observations; and Dr. Tom Kinman of NOAO for his help with the
classification.
