I've noticed venus is very bright in the early evenings before it sets here.
Much brighter than usual,
Brighter than saturn.
But it wasn't like that last year. Possibly something in the atmosphere?
I don't think there has ever been a time when Venus was NOT brighter than Saturn.
But yes, I noticed it last night with naked eye...seemed that the right side of Venus was "bulging".
Uhm...RLY? Or is this only a self-fulfilling wishful "prophecy"? Because two posts above we pretty much came to the conclusion it's a lens flare

hm.. lets say it is not processing artefacts or lenses artefacts. Let us not rush into labelling everything strange as being some technology glitch, already happened at least 4 times in December . Anyone remembers this?

I observed Venus last night. Was a great site next to the crescent moon. I did not see anything out of the ordinary visually.

Looking at the raw image, there doesn't seem to be anything going on. Yes, that's the full sized image. We need the high quality science data to get more detail.
I expect it's a processing artifact.
It's a lens flare. The processing they do dramatically enhances the appearance of faint low contrast features including lens flares off of bright planets like Venus. I did a (very rough) processing of the beacon images from the 18th and the 27th, making a pseudo-dark using data from 4 days prior to bring out the flare:
Image from today:
Image from the 18th:
The high quality data from the 18th is clearly your classic Venus lens flare:
It's not as easy to tell with the jpg versions of the beacon images, but when you process the raw fits of the beacons using pseudo-dark subtraction you can see it's the same type of lens flare as on the 18th, it's just the process is repeating itself in reverse as Venus leaves the field of view. If I have some time tonight I'll redo the processing more carefully by making a better pseudo-dark and use curves adjustment to the histogram without clipping it instead of clipping the heck out of it with a quick levels adjustment.edit on 27-12-2011 by ngchunter because: (no reason given)

Well I found something strange this moring with venus. What looks like a solar flare is clearly seen exting its atmosphere. I dont have a idea of what would be causing this or what it could be. Im also prettysure its not a regular thing for a planet to have what seems to be a solar flare type event in which a larger portion of the planets atmosphere is ejected into space. Hopefully somebody more knowledgeable then myself can shed some light on what we are seeing or if its really a unkown event. good day to you all!!

I made a gif out of the images.

The latest beacon mode image shows the familiar lens flare taking shape.
