What Planet did i see in daytime? at the griffith observatory?

Almost certainly Venus. If it's far enough away from the sun in the sky, Venus can be seen with the naked eye during the day, but you have to know where to look and be a bit lucky.

Anyone who says that all the planets can be seen through a telescope in daylight has been to observatories that I've never heard of. Some daylight observing is possible if the sun is low, but I'd be interested to hear from regulars who have seen Uranus and Neptune during daylight hours at a big observatory. Even if a mag 6 object is visible through straining eyes, why would they bother?

Venus is a planet that doesn't show any detail due to its thick cloud cover, so if it was Venus, the only notable thing you could have seen was a phase of Venus (much like the moon has half and quarter phases). The same would essentially be true of Mercury.

Jupiter is a very bright planet and could possibly be seen from an observatory very late in the afternoon about this same time of year. If you saw the whole planet and not just a phase it was definitely and outter planet, most likely Jupiter. If it was a phase like the moon it was either Venus or Mercury.

Whats up Paris, interesting that your asking as an alternative of answering. It's so much find it irresistible was once at the Getty when it opened. Remember? Parking on the GO is free, but the lot is so small, the city determined to just make it off limits and shuttle each person in, considering demand to see the expanded Observatory can be very high. So, the Observatory is free, but the shuttle is $8, and you have to make reservations. However, the Planetarium show, which has constantly been additional, is one more $7 adults/$5 kids. As OC1999 acknowledged, that you can park at Hollywood and Highland, or on the zoo. My option would be the zoo.

It could have been one of several. I personally have observed three planets in daytime (Mercury, Venus, and Jupiter) as well as two stars (Sirius and Procyon), and my telescope is a lot smaller than the one at the Griffith Observatory. Did it look like a half Moon (Mercury or Venus) or was it round with stripes (Jupiter)? Most likely it would be Venus, as that's what I show in my telescope most often in daylight.

Whenever I go to some observatory and they let me play with the dials (most of them know better), I enjoy seeing planets during the day (and even a few interesting stars).

All planets can be seen though major telescopes during the day, including Neptune, as long as they are well placed (not too close to the Sun, high enough above the horizon, etc.). Saturn is my favorite, but if it had been Saturn, in your case, you'd remember the rings.

What other feature do you remember about the planet (colour, shape...)?

Depending on the year, date and time (and clearly, the direction the telescope was pointing) it could have been several. Both my wife and I have seen Venus in the daytime without aid, and even a small telescope or binoculars makes it easier, if you know where to look. (My sextant telescope counts as having help pointing, when we have a good horizon (here at home in our part of Pennsylvania, there is no "horizontal" horizon, because of the hills, valleys and mountain ridges.

In answer to your specfic question, Venus would be most likely, and it would look usually somewhat like a half moon or crescent moon when it is at its brightest.

Jupiter would have looked round -- I doubt there would be enough contrast in daytime to discern its color bands.

Was it close to the sun distance wise and close to sunset or sunrise?

Could be.

However if it was midday and high in the sky, more likely Mars, Jupiter or Saturn.
