Any astronomy bros been tracking Comet Leonard?

I saw it a week ago in my 3" refractor when it passed in front of M3, and it's been cloudy for me ever since, so I'm excited for it to appear in a few hours. A friend in Arizona said last night that it's now visible with the naked eye. Look east before sunrise y'all.

Also a heads-up that this comet will be visible in the western sky just after sunset along with Venus by next week. Its dust tail could pass sufficiently close to cause meteor showers there (see article).

"On 14 December 2021 the comet ... will quickly become better seen from the southern hemisphere. The forward scattering of light could cause the comet to brighten to as much as magnitude 2."

Also a heads up that Venus is approaching conjunction, so if you zoom in on her you're in for a treat. Looks like a tiny pic related right now at a blazing magnitude -4.7

Update - tonight the comet was at the bleeding edge of naked eye visibility from my location (light-polluted area with 80%+ humidity). Underwhelming on that front, but still a solid target for binoculars or a small telescope. It'll brighten up significantly as the week goes on, but it's all clouds for me going forward.

Also a heads up that the Geminid meteor shower peaks next Monday:

>The meteors from this shower are slow moving, can be seen in December .... with the date of highest intensity being the morning of December 14. The shower is thought to be intensifying every year and recent showers have seen 120–160 meteors per hour under optimal conditions, generally around 02:00 to 03:00 local time.

Shameless self-bump. One of the numerous IQ or racebaiting threads deserves to die more than this one.

captured an image of it with an iphone and a 5 inch dob, pretty bad especially since I didn't take flat frames, but if it's gone forever I might aswell try
