Betelgeuse

Post by Christopher K. »

The "fainting" of the great supergiant Betelgeuse (usually one of the fifteen brightest stars in the sky) is a major topic of discussion within the professional and amateur ranks. Betelgeuse has dimmed to a pathetic (for it) magnitude not seen in recent skygazing history. A preliminary look at AAVSO estimates by Sarah Beck indicates Betelgeuse may be at one of its faintest points since 1893. Bob King estimates a magnitude of just 1.8(!) as recently as Monday.

On 14 February, 7:30pm at HRPO, a presentation entitled "The Current State of Betelgeuse" will be offered to the general adult public. There is no admission fee; the presentation will explain the type of regular variability Betelgeuse has, how this current dimming deviates from that, and what to expect in the future.

Happy Early Valentine' Day.
