Posted: Tue Jun 09, 2015 9:22 pm
Last saturday I've taken a look-around of symbiotic stars in the database - result at R~11000 (LHires + 35um slit, 2x2bin) around H-alpha, I could process them by only today:
T CrB:
Slightly increased.
V443 Her:
YY Her:
It was the hardest object, left peak increased a bit since last noisy exposure.
CI Cyg:
Having triple peak, good snr.
Z And:
Good snr, narrow and extreme strong H-alpha (increased a lot since last year).
Experimented with very short term (5-20s) exposures on CH Cyg 20150606.958 - 20150606.981, but found no visible flucuation above the high noise, otherwise all looked simple 1-peak state.
Cheers,
Peter
