Hi. I just joined the IMO today. I have been sporadically observing meteors for ~40 years (visual). I'm wondering if the old observations are useful to the IMO and whether I should add them as visual observations. I have records since the late 1990s - about 50 observations (I have yet to find my old observing records book - too many house moves). Historically I sent them to the NAMN. Your thought
This year RAMBo has recorded a strong Ursidi activity. In the attached graphics you can see that the maximun has begun at 270,800 of solar longitude. The first graphic shows the mass behaviour, the second one (red) shows the Hourly Rate. More informations on our web site www.ramboms.com
Both the North American Meteor Network (NAMN) website and meteorobs mailing list have been offline for the past couple months. Efforts to resolve server issues for the NAMN site were not successful. It appears now that our domain has been hacked and may be potentially unsafe to visit. Therefore, I have decided to end the online NAMN presence. You should refrain from visiting the site, and remove
I just realized, while reading the 2017 IMO Meteor Shower Calendar, that Mikhail Maslov made some predictions about a potential meteoric activity linked to 249P/LINEAR, with potential activity on April 20th, 2017, around 16h 33min UT. Meteoric activity would be associated to small meteoroids, so meteors may be faint, or only radio detectable. Does anyone (Mikhail, or
We are aware of potentially strong tau-Herculid shower in 2022. However my modelling shows that there are some chances for activity in 2017 on May 30 at 17:24 UT. I suggest that if any activity appears, it should very low, perhaps, at the level of separate meteors, but their brightness is expected to be high, so even 1-2 such meteors could make a lot of fun. Details are here:
Is there a minimum acceptable Lm for observing? For example, at my rural site, the Lm is around 5.8, so it's obviously fine. At my house in an urban area, clear nights are around 3.8-4.1. The reduced number of sightings is an obvious consequence, but are the observations still of use?
When observing minor showers for the first time, is it worth trying to do an association with a known shower, or leave the shower column blank and just fill in the magnitude distribution and number seen columns? The IMO guide seems to suggest that this is the way to go.
I observed the Geminids from my home town during the night Dec 13-14. Skies cleared up from the south around 0.30 UT. I went to my observing site up in the local hills and watched the shower for 5.25 hours Teff between 01.05 - 06.20 UT. Despite the presence of a full moon, meteor rates were pretty great with hourly visual counts of 44 - 57 - 45 - 44 and 30 Geminids (Lm 4.9 up to 5.1). At the end
Here is an interesting view of the Geminids (thanks Tioga for the forward), as we could observe them from the stratosphere! Interesting to see how a meteor behave in real time, from a different point of view. Must be much harder to associate meteors to a defined radiant from there ;-) https://twitter.com/pmisson/status/809011987476840448
Around 4:30 it's suddenly become clear in Wilderen(Belgium) and different Geminids were recorded by Cams and even two fireballs on the all-sky. The first one on the all-sky at 04:48 UT and the second one at 05:10 UT. All together 44 meteors were captured by Cams between 4:33 UT and 6:28 UT. Sometimes, there were two at a time.
