Symbiotic stars: T Crb, YY Her, V443 Her, CI Cyg. Z And

[Peter Somogyi]

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,
