21 Vul a new luminous long period delta Scuti star

Photometric observations of 21 Vul have revealed it to be a Delta Scuti variable star with one of the longest known periods, 0.227 d, among those variables. 21 Vul presented a short period amplitude variability of about 0.05 mag, and the log of its effective temperature was calculated to be 3.891.
