Weak lunar eclipse coming November 30

There will be a lunar eclipse the morning of November 30, 2020 but you may not want to get out of a warm bed to view it — it will be fairly “weak.” This month’s eclipse, viewable in its entirely from Northern Ohio (given clear skies) is of the penumbral variety and will not display the eerie colors that make total lunar eclipses so exciting.

A penumbral lunar eclipse occurs when the Moon passes through the thin outer portion of the shadow Earth casts out into space.

A penumbral lunar eclipse occurs when the Full Moon passes through the shady outer circle — the penumbra — of Earth’s shadow streaming out into space. Careful observers will note how most of Moon dims slightly with a sliver of a brighter southern edge and a darker northern area. During a total lunar eclipse, the Full Moon passes fully through the darkest portion of Earth’s shadow, the umbra, and is illuminated by the colors of the globe’s sunrises and sunsets. Again, that won’t happen this time.

Most of Monday’s event is quite subtle and takes a long time, many won’t even notice the difference. If you want to see this eclipse at its best, even photogenic, view it only around maximum. The penumbral eclipse begins [P1] at 2:32 AM, reaches its Greatest eclipse (you may note northern darkening) at 4:52 AM, and the event ends [P4] at 6:53 AM when Moon completes its emergence from Earth’s shade.

The next total lunar eclipse — the type that features coppery-red colors at its peak — will take place May 26, 2021; unfortunately, that event will reach its maximum as Moon sets locally. The next total lunar eclipse that we might see in its entirety will take place May 16, 2022 and that should be a doozie!

Rounding out the year

November and December will see two excellent speakers present talks, rounding out this most unusual year for the Cuyahoga Astronomical Association’s (CAA). COVID-19 isolation restrictions on group gatherings, and closed meeting facilities caused the club to take its meetings online via the Zoom cloud service. Normally the club hosts a December dinner in lieu of a meeting but since the dinner cannot be held, there will be a December “virtual” meeting complete with speaker.
