Objects Session Notes
- 3.5 hour session - main aim was to record further images of comet 73/P SW-3 and recent supernova - 2006bp, 2006bt. - opportunity was taken to acquire sequence of images of asteroid 2006 GY2, which is passing by Earth
(6.5 LD at closest approach).- moon at 100% phase (full moon)
(too low to image)- More Notes
As part of an ongoing project examining the variability
in the cepheid star RT Aur, further image sets of the variable were recorded
at the commencement of the session. Image sets comprised 7 sequences of
images (3 x 2s V & 3 x 5s B) alternated between RT Aur & reference star SAO 78571. These
and previous image sets from previous session from Feb-May 2006 were analyzed.
Results are shown in graphs below. Data is consistent with a regular
variation with a period of 3.728115 days. Quality control for this
variable is less tight than ideal due to the faintness of the available check
star (particularly in B). Data quality, particularly in B Band, suffered
from increasing Airmass through May, which hampered ability to confirm B-V
trends through the magnitude minima. Nevertheless the light curve for RT Auriga
has been reasonably well constrained by the total dataset.
