Misterious white dot

[Tusia]

This is my first moon shot with the new Olympus camera. It seems to have worked OK for the beginning.

My only problem is the white dot that keeps on appearing on every shot of the moon I take. It does not appear on pictures I take in daylight. Since it is my first DSLR, I wonder if ones of you with lots of experience can tell me if this is a normal optical glare/reflection (and how to minimize it) or is it something wrong with the lens (I still have a week to return the camera). Will appreciate your insights.



Camera: Olympus E-520
Exposure: 0.003 sec (1/320)
Aperture: f/5.6
Focal Length: 150 mm
ISO Speed: 100
Exposure Bias: 0 EV
Flash: On, Did not fire
Lens Type: Olympus Zuiko Digital ED 40-150mm F4.0-5.6

My first thought was that it was a star or planet in close conjunction with the Moon. But, if you're getting it in every photo similar to this it could be a hot pixel in the sensor. However, to my knowledge, hot pixels have more of a tendancy to show up in much longer exposures than this one. Also, hot pixels are usually either red or blue so being that this "spot" looks white, I'm not sure what it could be.

Sorry, I know this might not have been too helpful... but at least I made a half-assed effort.

Could it be akin to reciprocity failure or is that only in chemical photography?

Oooo maybe it is a dust on your sensor
just kiddin...something NASA should investigate, might be something to worry about

Will need to run pixel mapping (comes in Olympus camera). Found a very friendly and helpful bunch of Olympus users on Flickr. Highly recommend.

Hey, KazeFox. Good morning. You seem not to be a morning person at all. But just in case, I will forward this to NASA along with your recommendations.
