Algol magnitude
WebAlgol’s brightness is usually at magnitude 2.1, with 10-hour long eclipses occurring every 2 days, 20 hours, and 49 minutes, when the fainter Beta Persei Aa2 passes in front of Beta Persei Aa1 and the system’s magnitude drops to 3.4. At maximum brilliance, Algol matches the brightness of the nearby second-magnitude star Almach. Webthen the magnitude of Algol will be. 2.1 + 0.17 x 5 = 2.1 + 0.85 = 2.95. 0r 3.8 – 0.17 x 5 = 3.8 – 0.85 = 2.95. Now compare Algol with ε Persei. Is Algol brighter or fainter than ε Persei, if Algol is brighter then check your estimate again. And then decide if you would estimate the magnitude of Algol to be 2.8, 2.9 or 3.0.
