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...

The Lacrosse 4 rocket is predicted to make a magnitude 1.4 pass beginning at 6:54pm. The presentation "2018: The Space Year in Review" will take place at 7:30pm tonight.

Below is the NOAA forecast for HRPO's viewing time of 8:30pm to 10pm...
precipitation potential, 0%
sky cover, 3%
relative humidity, 67%
temperature, 3˚C
surface wind, E 3 km/h


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 "good" (4 out of 5). This evening's 20OGS operator is LSU physics professor Greg Stacy. The 20OGS will be in operation; however, the dropout will not be lowered as BREC maintenance is still working on its hydraulic cylinders. Telescope viewing will also take place at the front viewing pad. The first half of the viewing period will probably be better. HRPO will close at 10pm.

The 5 January 2018 rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

The Lacrosse 4 rocket is predicted to make a magnitude 2.4 pass beginning at 6:59pm. HRPO will have its main floor ready for patrons by 7pm.

Below is the NOAA forecast for HRPO's viewing time of 7pm to 10pm...
precipitation potential, 0%
sky cover, 5%
relative humidity, 69%
temperature, 6˚C
wind chill, 5˚C
surface wind, E 7 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). This evening's 20OGS operator is LSU physics professor Rob Hynes. The 20OGS will be in operation; however, the dropout will not be lowered as BREC maintenance is still working on its hydraulic cylinders. Telescope viewing will also take place at the front viewing pad. HRPO will close at 10pm.

The 6 January 2018 rating is...

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

Below is the NOAA forecast for HRPO's viewing time of 8:30pm to 10pm...
precipitation potential, 5%
sky cover, 25%
relative humidity, 73%
temperature, 2˚C
wind chill, -2˚C
surface wind, N 14 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 "poor" (2 out of 5). This evening's 20OGS operator is BRAS member and asteroid discoverer Merrill Hess. The 20OGS will be in operation; however, the dropout will not be lowered as BREC maintenance is still working on its hydraulic cylinders. Telescope viewing will also take place at the front viewing pad. The last half of the viewing period will probably be better. HRPO will close at 10pm; if the temperature falls below freezing anytime after 8:30pm, HRPO will close immediately.

surface wind, N 11 km/h


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 "poor" (2 out of 5). This evening's 20OGS operator is BRAS Treasurer Trey Anding. The 20OGS will be in operation; however, the dropout will not be lowered as BREC maintenance is still working on its hydraulic cylinders. Telescope viewing will not take place at the front viewing pad as the wind chill is already below zero. HRPO will close at 9pm as that is the predicted time the actual temperature will hit zero.

The presentation "The Final Iridium Flares" has been postponed until 9 February. There will be no lecture tonight. The sky viewing session will begin at 7:30pm.

Below is the NOAA forecast for HRPO's viewing time of 7:30pm to 10pm...
precipitation potential, 7%
sky cover, 63%
relative humidity, 57%
temperature, 8˚C
wind chill, 6˚C
surface wind, SE 8 km/h


Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "below average" (2 out of 5) and the seeing rating will be "average" (3 out of 5). This evening's 20OGS operator is BREC Center Supervisor Jordan Cobbs. The 20OGS will be in operation; however, the dropout will not be lowered as BREC Maintenance is still working on its hydraulic cylinders. The first half of the viewing period will probably be better. Both NASA-TVs will show a replay of the RS-25 engine fire test at 8pm. HRPO will close at 10pm.

NOAA has issued a Flash Flood Watch until 9pm CST. Additionally, NOAA's Hazardous Weather Outlook mentions "a potential for
localized flash flooding this afternoon into early this evening".

Due to this situation the Highland Road Park Observatory is closed to the public and Evening Sky Viewing is cancelled. Please be safe and follow NOAA's and meteorologists' suggestions for travel.
