All Sky Fireball Network April 26th, 2014

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com.

On Apr. 25, 2014, the network reported 9 fireballs.
(9 sporadics)

In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]

On Apr. 24, 2014, the network reported 19 fireballs.
(15 sporadics, 4 April Lyrids)

Near Earth Asteroids

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.

On April 26, 2014 there were 1466 potentially hazardous asteroids.

Recent & Upcoming Earth-asteroid encounters:

Asteroid	Date(UT)	Miss Distance	Size
2014 GG49	Apr 19	3.9 LD	31 m
2014 HP2	Apr 24	3.8 LD	15 m
2014 HU2	Apr 25	3.7 LD	22 m
2014 HM4	Apr 25	1.6 LD	18 m
2014 HW	Apr 27	2.1 LD	10 m
2007 HB15	Apr 28	6.7 LD	12 m
2014 HL2	Apr 28	8.8 LD	26 m
2014 HV2	Apr 29	1.4 LD	33 m
2010 JO33	May 17	4 LD	43 m

1997 WS22	May 21	47.1 LD	1.5 km
2002 JC	May 24	48.7 LD	1.4 km

Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
