Hello!
My name is Sonka Bruno.My AAVSO code is SBX.
I made observations of SV Cassiopeiae and I noticed
that the comparison star labeled 88 and West of SV Cas
has a magnitude of approximative 9.2 when compared
with 96 and 94 comparison stars. The 87 magnitude star
is much brighter than 88 (about 0.5 magnitude
brighter).
The chart used is from AAVSO PC3/1991.
Here are my observations:
2451957.3 9.4 87,96
2451973.3 9.3 87,96
2451977.3 9.4 87,96
2451981.3 9.2 87,96
2451987.3 9.3 87,96
The instrument: Refractor 100mm F/7
The AAVSO chart is PC3/1991
