IT'S a shooting star. No, it's a UFO. No, wait - it's a comet.

Anyone who has looked to the sky in Warwick after sunset could have gone through this exact thought process as they spotted a small bright ball with a tail passing through the sky.

That is anyone except Warwick Astronomy and Astrophotography's David Carvoss. He knew it was a comet straight away.

There are actually two comets flying through the atmosphere at the moment - one that can be seen with the naked eye, the other visible only through binoculars.

If you haven't seen them yet, do not panic because Mr Carvosso said they would be visible for another week.

"C/2011 F4 Panstarrs is visible to the naked eye and looks quite nice through a pair of binoculars," he said. "It should be fairly easy for people to snap a shot of this one as it is fairly bright.

"They need to look slightly left of where the sun sets and maybe a hand width up from the horizon.

"Keep watching and after 30-40 minutes it should be clearly visible.

"I would say that Panstarrs would give people the best chance to see a comet till about mid-March as it will eventually move below the horizon."

C/2012 F6 Lemmon is the comet visible through a pair of binoculars.

Mr Carvosso said it was a bit dimmer than the other comet but should still be visible in a dark location.

"It should increase in brightness for the rest of the month as it gets closer to the sun and closer to the horizon at dusk," he said.

"At the moment I have to use binoculars to see it as a fuzzy ball of light and the long exposure image to reveal some of the tail.

"Lemmon should be visible through into April and should start to get brighter for the rest of this month, hopefully becoming visible to the naked eye here in Warwick.

"Brightness of these things is a bit hit and miss. Sometimes they are brighter than predicted and other times they turn out to be a complete fizzer."

Comets, as described by Mr Carvosso, are "big chunks of ice".

As they get closer to the sun gas and particles are expelled, forming the tail of the comet.
