This coming Saturday, 23 March 2013, Singapore will be celebrating Earth Hour.

My friends and I will be conducting free stargazing sessions at Bishan - Ang Mo Kio Park from 7:30pm onwards. Location is just outside McDonald's at the park. As of now, there is no news of this park switching off its lights during the event.

If you are organising a stargazing event this saturday and would like to be listed here, please feel free to send me an email at

Just would like to highlight a few points especially to those who are new to Earth Hour celebrations in Singapore:

- The switching off at 8:30pm is NOT compulsory by any law. Only some participating organisations are supporting it. So do not expect the whole country to be in total darkness and be able to see the Milky Way stretching across the sky on Saturday.

- In addition to Jupiter, Moon and star clusters, do give Saturn a try tomorrow night! It rises at around 9:35pm from the horizon. The longer you can wait for it to rise higher, the better the view will be.

- For viewing of Planets, Moon and bright star clusters, you do not really need to go to a very dark location in Singapore. Thus, you may organise your own private Earth Hour stargazing sessions with family and friends in a relatively bright but more convenient place. Perhaps at someone's house and switch off all the lights for an hour (or longer) from 8:30pm.

Going to a darker outdoor location does have the advantage of lesser local light pollution which means lesser eye irritation of direct light shining at you or the telescopes. It can also enhance the of stargazing atmosphere and mood.

But visually, do not expect to see a lot of extra details for bright objects with the same astronomical equipment just because you are stargazing at a darker site in mainland Singapore. For example, you will not see an extra bigger Jupiter or surface details of its moon with the same amateur-size telescope.

So lets all pray for clear skies tomorrow and wishing all of you a wonderful Earth Hour stargazing session wherever you are!


Update 23/3/2013: Weather permitting, Richard will be deploying his 15.4-inch dobsonian telescope at Mandarin Orchard (Outside Mandarin Gallerythis evening in celebration of Earth Hour. More info:
