Hi folks:
Result of May 7 early am eta Aquarids ( parent body - Halley's Comet which give rise to eta Aquarids and the Orionids annually). Look at the 5am-6am composites. All these five were negative magnitude..

Clear sky to all!!

hi Chia,
You took the videos in Woodlands right? I watched the shower in NTU and saw 4 negative-mag ones in Saggitarius-Scorpius region at roughly same times, but didn't see any in the region shown on your screenshots.
Looks like the small geograhical offset in SG still makes big difference on meteors' apparent positions! It would be interesting if more people in SG living in different locations start doing video meteor monitoring!
Cheers,
Jia Hao

Clear skies please...
These are from the Sag/Sco region. See one of the eta aquarid with star map overlaid.

It will be interesting in the future to do a visual comparison noting the meteor direction/path vs background star and TIME information so a direct matching can be done. ( wthin FOV of course).
The only location ( and time) sensitive phenomena i knew of in this little Red Dot is iridium flares. The narrow beam of the reflected sun light make the difference. For meteors in our island there shouldnt be significant parallax..

Oops I underestimated the field of view of the camera, thought the camera was aming southeast instead of southwest judging by the moon's position.
Then the meteors we saw are in the same region, but there should still be some minor offsets, maybe a few degrees, since we are still around 15km apart. It would be an interesting project though, to figure out whether the small difference can be dectected visually~.

Jia Hao

Hi Airconvent/JH:
I am glad there are visual observers out there like Jia Hao etc and some lurking some where that have not reported their visuals yet.
With the popularity of dSLR and interval shooting capability , theoretically it is possible for Singastro folks to team up and set up 'electronic fence' to capture meteors in various part of the Island ( poke outside the HDB windows) and do the parallax exercises as JH mentioned. Visual description of the meteor sighted will be useful too. ( brightness, color, train, flaring... ).
Checked this morning video May 8 had only two eta aquarids due to non ideal sky ( flickering lightning).
