Bright meteor at the sky of Espirito Santo Brazil

On the night of May 3, three Exoss network cameras recorded a bright meteor over the south of Espirito Santo, Brazil.

Its maximum brightness came close to the magnitude of Venus. Applying the usual criteria of the meteoroid source analysis, together with its orbital elements, such as eccentricity , inclination , semi-major axis,...

Early May, 2017 ACAC observations of the eta Aquariid meteor shower from north Florida

Greetings again all, Members of the ACAC have already been out a few times in the pre-dawn (0400 – 0600 a.m.) monitoring the build-up of the 2017 eta Aquariids (ETAs) towards their maximum activity level over the next several mornings. Dave and Brenda Branchett have led the way from Deltona, Florida with several observations of moderate ETA activity so far.  I managed one hour’s observation  from the “meteor roof” of my home yesterday morning.  Here is the report on what we’ve been seeing: Observed for radiants: ETA:  eta Aquariids ANT: Anthelions ARC: April rho Cygnids SPO sporadic meteors May 3/4, 2017 Observer: Paul Jones. Location: 3609 Crazy Horse Trail, St. Augustine, Florida, Lat: 29.89.11 N, Long: 81.30.31 W (5 miles SW of St. Augustine, Florida) 0430 – 0530 EDT (0830 – 0930 UT) Teff: 1.0 hour, no breaks, LM: 5.2 sky conditions: clear, slight haze, facing: south 5 ETA: 0, +3(2), +4(2) 2 ANT: +2(2) 9 SPO: +1, +2, +3(3), +4(4) 16 total meteors All the ETAs were short-pathed (which is unusual for them).  The zero magnitude ETA flared a pretty golden color and left a short train.  The two ANT meteors were both long, slow and bright – very pretty meteors. Here are Dave and Brenda’s reports: Observer: Dave Branchett Location:  Lat 28.8766 deg N Lat 81.1803 deg W Private residence Deltona Florida. Date: 05/01/17 Time: 09:12 – 09:42 UT...
