Energy Efficient Night Lighting for Safety, Security, Health and the Environment

General Meeting Speaker: Debbie Moran

Deborah Moran is the 2017 recipient of the International Dark-Sky Association’s Hoag-Robinson Award for education of government officials about outdoor lighting issues. For the past three years she has shared her concerns about Houston’s retrofit of its street lighting with bright white LED lights, while at the same time, many cities across the US are switching from this disruptive lighting to more “responsible” low wattage warm or soft white LEDs.

Debbie has spoken multiple times at Houston City Council meetings and various Civic Organizations to educate them about the safety, security, health and environmental benefits of responsible night lighting. Responsible night lighting is recommended by the American Medical Association since the produce less glare and reduced disruption of day/night circadian function in people and wildlife. Such disruption can interfere with sleep and cause a host of health problems.

Upcoming Women's Observatory Training

Rene Gedaly, Observatory Trainer

The Mar 23 Women’s Observatory Training class is cancelled so we’ll try again Mar 30 and, if necessary, Apr 13. Here’s how signing up for Observatory Training works:

  1. The observatory will be tentatively reserved for class on non-prime Saturdays. 
  2. The week before class, the lead trainer will announce the possibility of holding class via the website, AstroList, and the HAS Facebook group. 
  3. The trainer will monitor the weather and announce that class will definitely be held as late as the Friday before the Saturday class. 
  4. Once the trainer announces class is a Go, email your RSVP to Observatory Director Chris Ober at [email protected]. Do not email your trainer. Chris will check your prerequisites and add you to the class. It’s first come, first serve to the first six students.

All prerequisites are on the website, but in particular, make sure you've taken this year's Dark Site Orientation or you’ll miss out.

Asterisms – Greg’s “3” Asterism

By: Steve Goldberg  (Posted 3/18/2019)

Asterism: a grouping of stars that form a recognizable pattern.
 
Constellation: Leo
Right Ascension: 09h 38m 00.0s
Declination: +15° 17' 00"
Magnitude:  8 to 11
Size: 15’ (minutes)
.
 

This asterism is called “Greg’s 3” because it was discovered by Greg Parker. It is located inside a triangle with stars Regulas α Leo, Eta η Leo and the “center” star in Cancer, Delta δ.  

 
 
 
 
 
 

 

 
In this eyepiece view, you can see the bright stars that make up the asterism. The circle FOV is with an eyepiece giving 80x.
 
 
 
 
 
 
 
 
 
 

 

 

 

 

Here is the asterism with the “3” drawn in.

 

Here is an article from 2013 in “Earth Science Picture of the Day” publication. Read the article here.
