Photoelectric Observations of SZ Lyncis
No. 88 (Vol 10, Part 2)
Budapest, 1986
Abstract
1018 photoelectric observations of SZ Lyn obtained at Kottamia
Observatories between 1984 and 1986 are reported. The long-period
variation in time of maximum light discovered by van Genderen was investigated
and the value of its period (PB= 1173.5 days = 3.213 years) and
semiamplitude (A= 0.00569 day = 491.6 sec) have been improved, and a secular
change in the pulsation period (B=3x10-12 day cycle-1) has been found.
