AAVSONet proposal for TU Tau, submitted by Robert Buchheim (BHU)
Goal: I (along with other participants in our Spectroscopy discussion group) plan to monitor the star for any spectral changes during this observing season. Contemporaneous photometry will allow us to flux-calibrate the spectra, thereby correlating spectral changes with brightness changes.
Requested observations: I request B-V-R observations of this star approximately every seven to ten days, from now through April 15, 2023. There are no time-critical events on this semi-regular variable star (SRB), so you can adjust the observing schedule as needed for weather or other higher-priority targets, or to avoid the Moon (which can pass close to TU Tau).
|Target||RA (H.HH)||Dec (D.DD)||Magnitude||Telescope||Observation Frequency||Expiration Date||Proprietary Term|
|TU Tau||5.753810||24.42011||7.7–8.8||BSM_NH2||5||April 15, 2023||No|
Committed to NH.
The following request was e-mailed to Ken Menzies, and he is "on it" (2022-11-20):
This relates to my project on TU Tau. After looking at the first two sets of images, I’d like to make two changes:
• Change the aiming to put TYC 1866-1160-1 (RA= 05 43 19.049, Dec= +24 48 40.15) at the center of the image. That will offset the target so that I get two good comp stars in the field (“75” and “76” on the chart).
• Change the R-filter exposure to 10 seconds (is currently 15 sec) – the target is close to the linearity limit in the R-images.
Telescope = BSM_NH2
