HD290380 eclipse
Posted: Tue Oct 09, 2018 3:11 pm
Dear all,
Last year in France I took spectra of HD290380 because of an AASVO alert concerning an eclipse by a planet/brown dwarf.
Only last evening I could take another one...... the green one is last year.
The SNR is very low (magnitude>10) but the difference is obvious!
Cheers Arnold
