*Moonrise = 7:38pm
*Sunset = 7:51pm
*Moon enters penumbra of Earth's shadow. = 8:32pm
*Moon Reaches 10° Altitude: 8:37pm
*End of Twilight = 9:23pm
*Moon enters umbra of Earth's shadow. = 9:27pm
*Moon Reaches 20° Altitude: 9:36pm
*Total Eclipse begins. = 10:29pm
*Moon Reaches 30° Altitude: 10:46pm
*Total Eclipse ends. = 11:53pm
*Moon exits umbra of Earth's shadow. = 12:55am
*Moon Culminates at 39°= 1:01am

Please bring a binocular if you have one. Do not bring any mechanical or electronic equipment that requires placement on the ground. Please sit or lie down only on grass--not concrete. Current predictions from Peat suggest six visible passes from 8:13pm to 9:24pm, the brightest of which is currently listed as magnitude -2.5! This list will be posted after the values are refined over the next few weeks.

Some advertising was released stating the upcoming Total Lunar Eclipse was on 18 May. That advertising is incorrect. The Eclipse begins the evening of Sunday 15 May. HRPO regrets the error.

The interesting color of the Moon during a total eclipse is due to a phenomenon called Rayleigh scattering--also responsible for the Earth's sky usually having a blue color.

All who lives in the greater Baton Rouge area are encouraged to alert your family, friends and coworkers. This will be the last total eclipse of the Moon this area will see in its entirety until March 2024.

As of this posting, the NOAA forecast shows four percent rain chance and ten percent cloud cover for Sunday night. LSU's professional-grade 20OGS scope will be unlocked from 10:45pm to 11:45pm, during the full emersion of the Moon into the Earth's shadow.

The Danjon Scale is a very useful tool for gauging the brightness of the Moon during the midpoint of a total lunar eclipse. The scale runs from "0" (very dark, Moon almost invisible) to "4" (bright red or orange, with possibly a bluish rim).

Please keep in mind, if Standard Time were being used HRPO would be open from 6:30pm to 12:30am...

The front gate will be open at 7:05pm. The main building will be open at 7:10pm. Below is the NOAA forecast for HRPO's planned viewing time of 7:30pm to 1:30am...
precipitation potential, 1%
sky cover, 27%
relative humidity, 77%
temperature, 31˚C
surface wind, SW 8 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time both the transparency rating and the seeing rating will be "average" (3 out of 5).

Peat predicts three visible passes from the viewpoint of HRPO grounds...
*the International Space Station, magnitude -2.0 beginning at 8:50pm
*an H-IIA 202 rocket body (Spacetrack #38341), magnitude 1.8 beginning at 8:59pm
*a Chang Zheng 4B rocket body (Spacetrack #29093), magnitude 1.1 beginning at 9:17pm
There is a chance to see a couple of sporadic meteors while the Moon is completely immersed in the Earth's shadow (10:29pm to 11:53pm).

Beautiful 28cm x 30cm graphic art prints commemorating the upcoming lunar eclipse have been provided by BREC's Marketing Department. One will be given to each interested patron who arrives at HRPO. First come, first take.

The 15/16 May 2022 rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

There is currently a NOAA Special Weather Statement that includes the HRPO area. There is now constant lightning, and periodic rain and thunder. HRPO is now closed.
