Event Date: May 26th
Time: 5:00 AM
Brief
Our morning northeastern sky showing continues today, highlighting another constellation: Perseus. Translated to 'the hero', he saved Andromeda from Cetus the Sea Monster. Refer back to this link that I included last month, regarding the myth including these two. Perseus rising with some stars labeled. The clock is forwarded 30 minutes later from yesterday's time to show the entire stick figure above the horizion. By the end of the season, it will be higher in the northeastern sky to see. Perseus' most popular star is Algol, which is an eclipsing variable.

Detailed
Algol's companion star faithfully transits it every 2 days, 20 hours and 45 minutes, dimming it from 2.1 to 3.4 in apparent magnitude. More detail about the dimming can be found here:
Besides Perseus and stars, I kept the stick figure of Aries to the right (south), and star Capella to the bottom-left (east). The star is to mark the evil (or 'ghostly') eye of Medusa, which as the myth states, Perseus is holding in his hand, As the classical illustration shows overlapping the stick figure here, the head of Medusa is shown near Rho Persei (Gorgonea Tertia).
Capella, stated above, rises shortly after most of Perseus' more visible stars, and is much brighter than any of them. I will show more of Capella as it gets higher and easier to see this summer during the morning; it is the brightest star of Auriga the Charioteer. The star is far enough north that as the Sun sets this month, Capella sets at about the same time. I will show that tomorrow. For now, sticking with Perseus, here is a magnification to more clearly show him holding his sword in his right hand, and Medusa's head in what appears to be a sack (is that term still used?) of some type.
