Here in Los Angeles there is a "Meetup" group called,
"LA UFO Channel", where a group of people will meet every 2 months or so, and will bring cameras and telescopes to view and capture "UFO's".....to celebrate and enjoy ufo or orb sightings in the Los Angeles skies.
These meetings will often start with a short meditation, led by a gentleman,
Robert Bingham, who will mentally "summon" UFO's or orbs to appear.
The bunk....they're just observing balloons.
Why ?
They (about 15-40 people) will always meet on a Sunday or holiday (check their schedule), and near a local park or overlooking several public parks, and then claim to see UFO's by sight, and in their cameras.
Why only on Sundays or holidays ?....(the trick) because this happens to be the most popular day(s) to see helium balloon releases, (especially over public parks) when birthdays, anniversaries, and family celebratory events happen, and helium balloons escape or are voluntarily released. Los Angeles is heavily populated by Hispanics, and they utilize balloons a lot, at parties on Sundays or holidays.
They take it seriously, but I can't help but laugh a little.
Some of their stranger "UFO's" items are easily found on party-supply sites, eBay, or balloon suppliers.
This hardest one I was able to find as a balloon, ....I suspect it was of a Mickey Mouse balloon...but I just went to google images "balloons" "mylar" "character"....there it was.
(I lost the link. I'll post it when I find it.)
Frankly, it looks like fun to be a 'balloon spotter'....but not so much fun believing their claims as to "why" they are there or what they are
