There are a number of rules and regulations that must be followed in exchange for being allowed to be at HRPO...
*No white lights are allowed. White light destroys night vision. Please keep headlights off. Please outfit your white flashlights with red construction paper, a red stretch balloon, red cellophane (several layers may be needed to make the light suitably dim) or a thin coat of red nail polish. Please do not use a camera flash upstairs in the dome or outside at the viewing pads without permission from the telescope operators.
*Blankets and lawn chairs are only allowed in the designated viewing area on the southwest side of the main building. You and your group may not use a isolated or secluded area away from everyone else. Please check in at the front desk beforehand. Please do not lie or sit on any concrete (viewing pad or sidewalk). If the ground is moist, bring a tarp or any fabric that can get dirty.
*If a telescope is not in operation, please do not handle it in any way. If a telescope is in operation, please wait until it’s your turn and place your eye to the eyepiece without touching the telescope.
*No glass containers are allowed.
*Pets and animals must remain under control and on a leash at all times.
*Please do not curse or use profane language.
*Litter and refuse are to be placed in proper receptacles.
*Running is not allowed outside at night, or inside at any time.
*Loud music is not allowed. Use headphones or earbuds; nearby people should not be able to hear it.
*Food and drink are allowed outside, and inside on the main floor, but not in either telescope dome or on either telescope pad.
*Alcohol and smoking are not allowed.
*As with any nighttime event at HRPO, there is no remaining on the property after the public program is concluded.

Kelly Beatty from Sky & Telescope has a thirteen-minute audio explaining the upcoming Total Lunar Eclipse...
https://www.skyandtelescope.com/observi ... r-podcast/

The Jet Propulsion Laboratory also has an excellent page with a wealth of information...
https://www.jpl.nasa.gov/edu/news/2019/ ... -supermoon

It will be extremely cold, with a zero wind chill. Below is the current NOAA forecast for 8pm Sunday to 2am Monday...
precipitation potential, 3%
sky cover, 1%
relative humidity, 61%
temperature, 4˚C
wind chill, 0˚C
surface wind, N 12 km/h


Anyone planning to use a lawn chair or sleeping bag (either at HRPO or elsewhere) should take precautions to ward off the cold:
*Follow all "camping in cold area precautions" appropriate.
*Consider a purchase of chemical-pack hand warmers and feet/toe warmers. Follow the instructions on the packs!
*Wear mittens or gloves, and thick outdoor socks.
*Wear headgear to keep heat from escaping via your skull.

HRPO is open for the Total Lunar Eclipse. Below is the NOAA forecast for HRPO's viewing time of 8pm tonight to 2am early Monday morning...
precipitation potential, 0%
sky cover, 0%
relative humidity, 84%
temperature, 2˚C
wind chill, 0˚C
surface wind, NE 5 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "average" (3 out of 5) and the seeing rating will be "good" (4 out of 5). This event is basically an unaided-eye event. However, there will be moderate-aperture telescopes providing low-magnification views of the Moon. Patrons are strongly recommended to bring binoculars; patrons cannot bring any equipment that requires a set up on the ground.

The 20 January 2019 rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

Bob King and Richard Talcott have summaries of the major points to follow while viewing a lunar eclipse...

The Moon rose ten minutes ago. It will be its highest in the Baton Rouge sky (due south of course) at 12:18am.

If you decide to become a citizen scientist and to take a Danjon estimate between, say, 10:56pm and 11:28pm, be sure to report your L estimate to Joe Rao (skywayinc@aol.com) and/or Richard Keen...

HRPO had a wonderful night, with a lot of people--and I mean a lot. The parking lot was full.

Since the actual temperature is now freezing, HRPO is closing at 1am.

BRAS President Steven Tilley has directed our attention to a lunar impact that happened during the Eclipse! It took place at 10:42pm, near the exact moment totality began.

Here's one shot...

Hopefully, there are more!
