Asteroid: A large space rock that stays in space. These rocky objects orbit the sun and are much smaller than planets.
Bolide: The light emitted by a large meteoroid or asteroid as it explodes in the atmosphere. Sound can sometimes be produced.
Comet: A solid body made of ice, rock, dust and frozen gases. As they fracture and disintegrate, some comets leave a trail of solid debris.
Fireball: A very bright meteor. It is brighter than the planet Venus. There are several thousand meteors that are bright enough to be fireballs each day. Most occur over the ocean.
Meteor: Sometimes called shooting stars. These are space objects that can as small as dust or as large as a rock. Once they enter the Earth’s atmosphere they are heated by friction burn up. The light emitted when traveling through the atmosphere is the meteor.
Meteorite: A meteor is able to survive the hot entry into the Earth’s atmosphere and reach the ground.
Meteoroid: A smaller asteroid or space rock that can orbit the sun and become meteors if they enter the Earth’s atmosphere.
Meteor Shower: An annual event, when the Earth passes through a region having a great concentration of debris, such as particles left by a comet. From Earth, it looks like meteors radiate from the same point in the night sky.
Solar Eclipse: When the Moon moves between Earth and the Sun and the 3 celestial bodies form a straight line: Earth–Moon–Sun. Solar eclipses only occur during a New Moon.
Total Solar Eclipse: When the Moon completely covers the Sun, as seen from Earth.
Partial Solar Eclipse: When the Moon only partially covers the disk of the Sun.
Annular Solar Eclipse: When the Moon appears smaller than the Sun as it passes centrally across the solar disk and a bright ring, or annulus, of sunlight remains visible during the eclipse.
Hybrid Solar Eclipse: A rare form of solar eclipse, which changes from an annular to a total solar eclipse, and vice versa, along its path.
Lunar Eclipse: When Earth comes between the Sun and the Moon and blocks the Sun's rays from directly reaching the Moon. Lunar eclipses only happen at Full Moon.
Total Lunar Eclipse: When Earth's umbra – the central, dark part of its shadow – obscures all of the Moon's surface.
Partial Lunar Eclipse: When only part of the Moon's surface is obscured by Earth’s umbra.
Penumbral Lunar Eclipse: When the Moon travels through the faint penumbral portion of Earth’s shadow.

— Since the first day of spring, March 20, the days have become longer and the strength of the sun has increased.
This change in incoming solar radiation will directly impact the rise in our daily average temperatures.
Typically during this time of year, overnight lows fall to the lower 40s, but that doesn't mean some nights can't be cooler.
In fact, according to the National Weather Service, the average last date of 32 degree temperatures is around April 19, but have been recorded as late as May 21 for Dayton.
While we can see freezing temperatures into May, it's the warmer days that trigger the beginning of the growing season.
Areas south of I-70 generally start their growing season before our northern communities.
Because of this, on nights when temperatures drop close to freezing, the National Weather Service will begin to post freeze warnings.
Dependent upon how far into the growing season we are, there may be time when only the southern counties get placed under a warning.
As more vegetation is evident in northern counties, freeze warnings will then be issued if necessary.
There could be a few days to a couple weeks lag between growing seasons in the Miami Valley.
