Hello all, I will be sending the annual card and gift card to Charlene Bootland, in appreciation for allowing amateur astronomers to continue using the private property (linked below) in Stewartville, located about one hour west of Ottawa. As you may be aware, Tom Bootland has sadly passed away last year. Charlene and her children are now looking after the property. If anyone would like to contribute to the gift card, please let me know by emailing me at meteorshowersca at yahoo dot ca I am happy to accept an eTransfer. Please note that the observing site is not yet available due to the Spring thaw. I will keep the group posted after I receive an update from Charlene. Clear skies! - Pierre

Hello everyone! A few people have been asking me if it's worth braving the cold tonight to attempt observing the Geminids meteor shower. Tonight is the peak, and the sky is expected to be clear around the Ottawa region... although it'll be cold (down to around -15C to -18 plus windchill). The Geminids have long been my favourite annual meteor shower. It is consistently active every year, produces a lot of bright, colourful meteors that move gracefully through the winter constellations, and under the best observing circumstances, they can reach up to 100 or more meteors per hour! The Geminids are also visible all night. For the Ottawa region, the radiant is low at 6 pm (local time), so only low rates can be expected. By 10 p.m., the radiant near the bright star Castor is 40 degrees high, and already plenty of Geminids can be seen. The radiant reaches its highest point in the sky at 2 am, and Geminids will appear to drop down in all parts of the sky. Unfortunately, this year's Geminids will be severely hampered by a nearly Full Moon. Only the brighter meteors will be visible. On the plus side, the weather forecast for tonight looks excellent (but cold). During the 2022 Geminids, a 74% gibbous moon was up for most of the night and reduced significantly the sky darkness during the optimal viewing times (that is when the radiant is high up near the peak of the shower). Despite the Moon's presence, I went to a dark sky site east of Ottawa. I was fortunate to have good sky transparency — free of any clouds, humidity or haze. I could see stars as faint as 5.4 (normally can see up to 6.2 from the same location on moonless nights). It was also quite cold with the wind. Was it worth it? OH YES! During the best observing hours, I had visual rates of 48, 52 and 62 Geminids per hour! Sometimes, I would see 2 or 3 meteors within a few seconds, and a few minutes of inactivity. But I was impressed at seeing so many meteors with a bright moon in the sky. In 4.5 hours of actual viewing time, from midnight onwards, I counted 287 meteors — exceeding my expectations! I'm not so sure that I would expect to see as many meteors tonight as the Moon will be even brighter. Tonight, the Moon will no doubt reduce significantly the display and wash out most Geminids. The fainter meteors will be invisible. In my opinion, a good proportion of Geminids are bright enough to punch through the moonlight! It really helps to have a good open view of the sky, away from trees, buildings or other obstructions. Rural sites will also have an advantage by having less artificial light pollution — therefore, less total light pollution to contend with. According to the IMO, the nominal peak time of the 2024 Geminids is predicted at 01h UT (which translate to around 8 p.m. EST) on the evening of December 13 (tonight!). The peak is quite broad, and can last several hours, followed by a sharp drop in rates. During the early evening, the radiant will be a little low, and the Moon will be very high and hard to avoid. It might be a better strategy to wait until 10 or 11pm, for the radiant to be much higher. Facing the north or east and looking a little lower will keep some of the moon's glare behind you. If you look towards the north around 11pm, any Geminids will appear to drop down towards the horizon. Geminids that appear further away from the radiant also tend to have longer paths. These can be easier to spot than the short Geminids near the radiant. One more strategy is to skip the first half of the night, and get up to watch during the last hour or two before dawn (say 4 a.m. onwards). The moon will still be up but much lower over the western horizon. For instance, the Moon will be only 17 degrees above the western horizon at 5 a.m. It will then be easier to avoid its glare. There is also a possibility that the Geminids could switch to brighter meteors and fireballs late tonight as the Earth starts to exit the stream (an effect known as "mass sorting"). In a nutshell, the Geminids are considered to be the best annual shower, along the Perseids and sometimes the Quadra

One of the caps for my 22 mm Nagler EP has disintegrated. I used to get replacement EP caps (might be the one that disintegrated) from Focus Scientific, but RIP. Does anyone know how to get replacement caps?

Hi Paul, How was the RASC star party last weekend? I was not able to attend. I have not seen any reports. Mike On Sep 18, 2024, at 9:58 PM, PolyWogg <thepolyblog@...> wrote: ?

Salut les OAFS, I'm wondering if anyone has a copy of the Xerlox books by Harry Adams - there was one for Messier and one for finest NGCs. Mine is rather ?magané?... I wonder if perhaps there is a pdf of this most elegant set of maps. Merci! Pat

I have public dem to do for my club on a new solar telescope nad also have some kind of gadjet for putting my cell in back of the coronado taht gime me beautifull images I plan to shar the images whit the cell software https://support.google.com/android/answer/9286773?hl=en#zippy=%2Cshare-content-with-someone do someone in the grop are interested to help to start this new way to share observation I need tester whit androide or maybe and other metod better whit route and wyfy

Hello all, In case anyone else is interested in observing tonight, FYI I'm planning to observe at FLO for a few hours. I'll likely arrive around 9:00 and observe until after midnight, as conditions allow. Matt

Hello all! Raymond and I are heading out to the Irvine Lake Airstrip (aka Nirvana) to observe the Perseids tonight. We plan to arrive before dark to setup, and stay the night until morning. Road map for Nirvana: https://www.google.com/maps?q=45.029722,-77.264200&hl=en CSC for Nirvana: https://www.cleardarksky.com/c/Rod1ArsrpONkey.html The road going in to the airstrip area has been repaired a few years ago and is now much easier to access. It is a very dark site, about 2.5 hours west of Ottawa. If you would like to join us, it's recommended to arrive before dark. But no worries if you are arriving later. Company is welcome! P.S. Fantastic auroras last night!!! Here's a few iPhone shots I took from Orleans that I posted earlier today on the OAOG's Facebook page: https://www.facebook.com/OttawaValleyAstronomy Clear skies! - Pierre

Hello all! The sky is expected to clear up this evening, with good sky transparency at Bootland Farm after midnight. The forest fire smoke particles in the atmosphere have also appear to have mostly dissipated (for now). I plan to be at Bootland Farm to do meteor observing from about midnight until morning. A few friends might be joining. All are welcome! I am unsure how good the weather will be for the Perseids peak nights next Sunday and Monday nights, and meteor rates are already kicking into high gear! : ) For those of you new to the group, you can find the maps, and instructions for the Bootland Farm site in the files section of the group... /g/oaog/files/Maps/Bootland%20Farm Clear skies! Pierre P.S. Weather also looks good for tomorrow night, but I haven't decided where to go observing.

Hello all! Very nice Perseids seen last night! Raymond and I will be setting up at Bootland tonight, staying from evening until morning. All are welcome to join us! Maps and driving directions available here in the groups files section: /g/OAFs/files/Bootland%20Farm%20dark%20sky%20site%20%28near%20Stewartville,%20Ontario%29 Note: possibly very dewy and quite tall grass, bring water proof boots. Clear skies! Pierre

Hi all, I will head over to Bootland Farm tonight for meteor observing from about 1am to 4am. The sky is expected to clear at around midnight with very good transparency. If you are up for some late night viewing, come on over! : ) Note that the grass is quite tall in the field. I also recommend good boots as the field will be wet from all the rain. Cheers! - Pierre
