The Highland Road Park Observatory (located at 13800 Highland Road) periodically has sky viewing, usually using telescopes. LSU owns two professional-grade Optical Guidance Systems reflectors. BRAS and BREC own several smaller ones.

Approximately three hours before any public event with sky viewing is to take place, I will post the NOAA forecast for HRPO. The forecast parameters posted will include precipitation potential, sky cover, relative humidity, temperature (with heat index or wind chill in applicable) and surface wind. I will also post the "transparency" and "seeing" estimates from Attilla Danko.

Finally, I will post a rudimentary HRPO Sky Viewing Rating derived from the data listed above. That Rating will be one on a scale of six values: Excellent, Very Good, Good, Fair, Poor, Bad.

For NOAA data, I use the "pinpoint" forecast for Village St George...

NOAA’s current forecast for the HRPO area is stating the following…
*Winter Weather Advisory until 12am
*Wind Chill Advisory beginning at 9pm
*Hazardous Weather Outlook for tonight which mentions “hazardous travel conditions”.

Because of all this, we will not have either the Friday Night Lecture or the Evening Sky Viewing tonight. The lecture “2016—The Space Year in Review” will be moved to Friday 3 February at 7:30pm.

At this time, neither Science Academy nor Learn Your Telescope tomorrow are affected; we are still planning to have those offerings. Drive safely, and cover exposed pipes.

Due to the actual temperature forecast to be below freezing before viewing time begins, and due to a Hard Freeze Warning from NOAA beginning at 9pm CST, the Highland Road Park Observatory will remain closed tonight as well.

The Hubble Space Telescope is predicted to be seen from HRPO grounds beginning at 6:22pm CST; anyone who arrives early can watch it with us.

The presentation "Star Clusters" will take place at 7:30pm tonight. The speaker is LSU physics undergraduate Rory Bentley.

Below is the NOAA forecast for HRPO's viewing time of 8:30pm to 10pm...
precipitation potential, 3%
sky cover, 51%
relative humidity, 84%
temperature, 18˚C
surface wind, E 6 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 "average" (3 out of 5). Tonight's 20OGS operator is BRAS member Peter Lazar. HRPO will stay open until 10pm.

The 13 January 2017 rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

The Hubble Space Telescope is predicted to be seen from HRPO grounds beginning at 6:12pm CST; anyone who arrives early can watch it with us.

Below is the NOAA forecast for HRPO's viewing time of 7:30pm to 10pm...
precipitation potential, 4%
sky cover, 61%
relative humidity, 79%
temperature, 18˚C
surface wind, E 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). Tonight's 20OGS operator is LSU professor Greg Stacy. HRPO will stay open until 10pm.

HRPO will not assign a Rating to tonight's sky viewing time due to disparate data.

The presentation "Wonders of the Winter Sky" will take place at 7:30pm tonight. The speaker is BREC Education Program Specialist Amy Brouillette.

Below is the NOAA forecast for HRPO's viewing time of 8:30pm to 10pm...
precipitation potential, 51%
sky cover, 89%
relative humidity, 82%
temperature, 21˚C
surface wind, S 8 km/h


Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "too cloudy to forecast" (0 out of 5) and the seeing rating will be "poor" (2 out of 5). Tonight's 20OGS operator was to be BRAS member Merrill Hess. However, there will be no viewing and HRPO will close at 9:15pm. If it begins to rain anytime after 8:30pm HRPO will close immediately.

The 20 January 2017 rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

[Note: Usually the red lights are on during public-welcome time. However, since it has already rained and outside surfaces are wet the lights for safety reasons will remain off.]

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "bad" (1 out of 5). Tonight's 20OGS operator was to be BRAS Secretary Ben Toman. However, there will be no 20OGS viewing; viewing will be attempted with a portable telescope on the front viewing pad. HRPO will close at 9:30pm. If it begins to rain anytime after 7:30pm HRPO will close immediately.

HRPO will not assign a Rating to tonight's sky viewing time due to disparate data.
