The Geminid meteor shower will occur soon, and once again HRPO will open during the peak nighttime period which at this time is slated for 13/14 December. The Highland Road Park Observatory will be open on Wednesday 13 December from 9pm to 1am for public viewing. The waning crescent Moon will be below the horizon for the entire viewing period! All participants must follow city ordinances, park rules and personnel instructions while on observatory property.

The 2 December Science Academy session will focus on the difference between sporadic meteors and those produced during a so-called "shower". Science Academy is for eight- to twelve-year-olds and costs five dollars per in-parish child and six dollars per out-of-parish child. Parents can register the day of the session (assuming it's not full) or register online via WebTrac. There is a maximum of sixteen slots per session.

The nighttime periods of 11/12 December from 11pm to 3am, 12/13 December from 11pm to 3am and 13/14 December from 10:30pm to 2:30am are the best times to search for Geminids. Keep in mind that periodically one may see a meteor from a weaker shower, or a meteor that is sporadic (not related to any shower).

At 7pm CST on NASA-TV1, a live discussion on why NASA studies meteors and meteoroids will be broadcast.

All those who attend the HRPO event should enter the main building to receive instructions for patrons. This is very important.

In JPL's "What's Up for December" video, a chart is shown estimating the rate per hour during the peak Geminid nighttime period. Accounting for light pollution as estimated by Danko, I have worked out an estimate. (Wow.) If this estimate of mine is worth anything, as viewed from HRPO the shower may yield during these hours...
13 Dec, 7pm = seven to fifteen streaks
13 Dec, 8pm = eight to fifteen streaks
13 Dec, 9pm = eight to sixteen streaks
13 Dec, 10pm = eight to seventeen streaks
13 Dec, 11pm = nine to twenty streaks
14 Dec, 12am = ten to twenty streaks
15 Dec, 1am = ten to twenty-one streaks
Some of these streaks may be quite dim. The waning crescent Moon rises at 3:32am.

HRPO's front gate will be open to patrons at 8:30pm. Patrons must claim positions on the grass (not concrete) on the south side of the building complex.

Below is the NOAA forecast for HRPO's viewing time of 9pm to 1am...
precipitation potential, 0%
sky cover, 34%
relative humidity, 85%
temperature, 8˚C
wind chill, 7˚C
surface wind, SW 8 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). There will be no 20OGS viewing tonight. There will be telescope viewing on the front and back viewing pads until 11pm.

Before 11pm, face south. After 11pm, any direction is fine to look for the Perseids. Look one-third to two-thirds up above the horizon.

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