// Personal comments
No activity of nu-Hydrids (NHY) and alpha-Leonids (ALL) detected.

One SPO was in fact an apex meteor with magnitude +2.

One SPO could be a member of a possible f-Herculids (FHE) shower,
as described by Sirko Molau & Javor Kac in WGN 37:3 (2009).
It had a very similar angular velocity and the radiant position
within the error limits of optimum radiant diameter.

// Personal comments
The showers nu-Hydrids (NHY) and alpha-Leonids (ALL, both nothern NAL and southern SAL)
didnt show any activity supposed by the IAU working list of cometary meteor showers.

The gamma-Normids (GNO) werent observed by me, because of the too northern latitude.

One SPO could be a member of a possible f-Herculids (FHE) shower,
as described by Sirko Molau & Javor Kac in WGN 37:3 (2009).
It had a very similar angular velocity and the radiant position
within the error limits of optimum radiant diameter.

Meine vierte Märznacht.

Interessant war sie wegen der f-Herkuliden (vermutlich aktiv vom 1. bis 9. März), die von Sirko Molau und Javor Kac in WGN 37:3 (2009) beschrieben wurden. Laut dem Artikel findet das extrem schwache Maximum bei 346° Sonnenlänge, was etwa 3:00UT 7.März 2011 entspricht, also genau zu meiner Beobachtungszeit. Da habe ich um 3:36UT ein Meteor gesehen, was nach einem sehr radiantnahen f-Herkulid aussah. Von daher interessiert es mich brennend, ob noch jemand in den letzten richtig schönen Nächten Meteore beobachtete und eventuell die Aktivität von f-Herkuliden bestätigen kann?

Ja, und mal allgemein an alle – schreibt eure aktuellen Beobachtungsberichte, bitte! Das ist wichtig!

No activity of nu-Hydrids (NHY) and alpha-Leonids (ALL) detected.

One short SPO at 3:36UT with medium-fast velocity and magnitude +3
could well be a very radiant-close (D=5°) f-Herculid (FHE);
WGN 37:3 (2009) states that the maximum of FHE takes place at 346° sol,
which corresponds to approx. 3:00UT on the 7th of March 2011!

One SPO at 2:03UT was in fact an apex meteor with magnitude +4.
