11th mag. star visibility? Mimi Occultation 7 May, Ireland

I was checking simulations of your dayligt and darkness times in Ireland with Starry Night...
I have a question:
Is it possible at this time of year (early May) to locate and observe an 11th mag. star from Ireland, at 21:15 UT, if it is at 29 degrees altitude, due West?
Let's say it is very close to Tejat Prior and Tejat Posterior.
: : : :
I am asking this in order to check an upcoming asteroid occultation event in Ireland.

Vagelis,
I think it is simply going to come down to seeing conditions based on an observer's location. Some of Ireland's south and west coast enjoys almost-to-the-horizon clarity at times. However, the more we go into summer, Irish skies become more hazy regardless. Ireland seems to experience many micro climates across this relatively small island.

Seanie.

Dont know the answer to your specific question Vagelis but a bit of confusion can arise with the two star names you picked.

Most modern atlases call "Tejat Prior"(Eta Geminorum) just "PROPUS"
and they call "Tejat Posterior" (Mu Geminorum) just "TEJAT".

Dont know why they changed the names.
Both stars are the "signpost" stars to M35.

I still call them Tejat Prior and Tejat Posterior myself.
Those were the names in my childhood star atlas!

Right, Seanie, local seeing is everything.
Well, I was going to propose to those who would like to try to observe an asteroidal occultation the Mimi event: www.asteroidoccultations.com/2008_05/0507_1127_16870.htm



And I have prepared a google simulation of the irish path here:

Steve Preston gives it a rank of 73/100, which is quite respectable.
Oh, and the star is actually 10.9 mag! (TYC 1323-121)
Another problem is that there 's a rich star field down there at Gemini feet, by the Tejats, Mark, so it needs an extra effort to locate it..
Good Luck!

I doubt it Vagelis, at 9.15 GMT (=10.15 summer time here) is the sky is still bright.
In mid summer the sky here doesn't go dark at all, we can see the sunglow on the northern horison at midnight for a good part of the summer,
On the flip side, you can go observing at 5.30pm and finish up at 7am in mid winter if you like.

I was afraid of that, Dave.
Starry Night showed no mercy, when it presented the 53 deg lat. bluish skies, but you know, hope dies last.
