Trying to observe V404 Cyg...

[Paolo Berardi]

Another attempt with Lhires III 150... V404 Cyg tonight (21:15 UT) appears significantly fainter than yesterday (when was shining at mag V 15.8).

AAVSO light curve has not yet updated, last observations (morning of 28 june) provide a V mag between 16.5 and 17.

Working console (the H-alpha emission is always relevant in the dark subtracted single frame):

Edit: it seems the star has become brighter at 23:30 UT
