About 270 pilot whales be-
came stranded on Tasma-
nia West Coast. At least 25
of the animals are believed
to have died already.
"To see a stranding like
this is not unusual. It just
doesn't happen every day"
said Vanessa Pirotta wild-
life scientist.
A helicopter crew spotted the
large pods of long-finned pilot whales 9 kilometres outside
the river mouth. These whales became stuck on sandbars in
Macquarie Harbour, on Tasmania West Coast.
Marine conservation experts performing a massive rescue
operation to try and save these blue water mammals. Around
60 people with all specialized equipment are involved in the
team. Out of which 40 are parks and wildlife staff. Remaining
are personnel from nearby fish farms, which have supplied
boats.
The success of the rescue operation would depend on how the whales respond.
Pilot whales are a species of Oceanic dolphin that grows 7 meters long and can weigh up
to 3 tonnes. It is not known why whales sometimes beach themselves. Authorities say
they are known to follow a leader, as well as gather around an injured or distressed
whale.
However, Olaf Meynecke, a whale researcher and Project Manager of whales and climate
at Griffith University, told Reuters "Their social groups and strong bonding between the

groups causes often all of them to strand."
Tasmania is the only Australian state where mass stranding of whales and dolphins regu-
larly occur. But it is seen to be the biggest mass stranding in more than a decade. In
2009 around 200 whales beached themselves off the coast of Tasmania.
The regional manager north-west with Tasmania's Parks and Wildlife Service, Nic Deka,
told reporters on Tuesday "We've rescued about 25 at the present time and escorted
them out the channel and out to sea and crews are continuing to work, so that number
will increase before we get to the end of the day."
Welcome Solar Cycle 25

CYCLE- the sequence of regularly occur-
ring events.Few known cycles-water cy-
cle, mineral cycles, etc. The uncommon
cycle with interesting facts is the SOLAR
CYCLE.
Sun is a bright shinning, huge gas ball
moving constantly. This movement of the
gases produces a magnetic field and the
sun behaves as an electromagnetic bar
with north and south poles. The magnetic field produced gets tangled or stretched and
causes switching of the poles i.e. north pole becomes south and vice versa in a span of
11 years (8-14years).
SUNSPOTS- The Magnetic field produced in sun results in the formation of dark spots on
the sun's surface, limiting the energy transfer and reduced surface temperature. Solar
activity is the measure of the sun's magnetic field. The SUNSPOTS helps in tracking the
solar cycle by alterations in the sun's activity.
The Solar cycle has two major stages- Solar Maximum (most sunspots) and Solar Mini-
mum (least sunspots) and the time from one minimum to the next is called a Solar Cycle.
The beginning of a solar cycle is called Solar Minimum, solar activity is less so there are
fewer sunspots but as the activity increases the number of sunspots also increases
called Solar Maximum. As the activities proceed the number of sunspots decreases,
reaching the stage Solar Minimum marking the beginning of a new cycle.
The numbering of the solar cycle started in 1755, and Today lets welcome the new solar
cycle 25. This 25th cycle started in December 2019 but the sun is a variable star, it
takes about 9-10 months to confirm the beginning of this new cycle- SOLAR CYCLE 25.

AFFECTS OF SOLAR CYCLE:
The poles reversal because of gaseous move-
ment on the sun's surface produces current and
the current sheet. Earth revolves around the sun
hence, affects weather.
The current sheet absorbs the cosmic rays pro-
duced by high energy particles in space and de-
flects them from entering thus, protects Astro-
nauts and space crafts.
Ejection of Plasma (charged gases) from the sun, produces solar flares and winds affect-
ing radio communication and space weather.
If there is low solar activity, fewer sunspots resulting in cold temperatures and vice-
versa.
Although, it is believed that the strength of the
solar cycle is decreasing over the period but it
can be still concluded that the effect of SUN will
always be there in our life.
Wild Fires

WILDFIRES-A CAUSE OF WORRY--SPEEDING
UP GLOBAL WARMING OR THE OTHER WAY
ROUND.
A series of out of control fires broke out across
California in August. Almost 14,000 firemen
have been sent to drench the fires. This fire
has destroyed huge sections of land.
Inhabitants of San Francisco and a few other
areas over the US' West Coast got up to orange
skies. Numerous parts were covered in orange to rust-colored skies.

Solid breezes kept on carrying smoke and debris
from the rapidly spreading fires toward the
northern parts of California. The winds known
as SANTA ANA winds are a naturally occurring
phenomenon that regularly peaks during the au-
tumn. Such breezes can assist fires in develop-
ing quickly. They spread rapidly and turn out to
be fatal.
The smoke and debris get significantly thicker
near the rapidly spreading fires. It can remove
the daylight totally, making it resemble the dead
of night,
As per NASA, the skies are an aftereffect of smoke particles. This blocks certain wave-
lengths from the sun. The smoke particles from the flames permit longer wavelength
colours like red and orange to pass. It obstructs the short-wavelength colours of yellow,
blue, and green. These longer wavelengths give the sky a red or orange colored appear-
ance. The same happens during sunrise and sunset.
What decides the shade of the sky is the manner in which our eye gets light. It gets it from
the sun through the atmosphere. When all light effectively goes through a clear atmos-
phere then all the colours which make up the spectrum are identified by our eye as 'white
light.
The important factors on why California and other areas of the world are encountering so
many wildfires year after year are.
•the environmental change brought about by the consumption of non-renewable energy
sources.
•poor fire management.
In a period of pandemic and catastrophic events, orange skies are one more sign 2020 is
to be associated with.

Well, the IPL is here. It started
on 19th September and will go
on till 8th November, in Dubai.
We finally have some sporting
events being telecasted. A
break from the monotony and
a ray of hope for sports lovers.
Although Tennis and a few
other sporting events had re-
sumed a few weeks back. In
India, Cricket being the most
popularly watched sport, the
excitement has built up only
now.
Well, so it has been a while; and it is quite evident from the extra ounces of weight most cricket-
ers have put on, around their usually flat tummies. But haven't we all put on a little, with all that
delicious home-cooked food we have all been eating, the last couple of months? In my humble
opinion, it makes the cricketers look humane. That said, all's good until it doesn't impact perfor-
mances. After all, we love our IPL masala packed.
So far, Deccan Chargers (DC) and Sun Risers Hyderabad (SRH), have lost the one match they
played; and Mumbai Indians (MI), Chennai Super Kings (CSK), Kings 11 Punjab (KXIP), and
Royal Challengers Bangalore (RCB) have won one and lost one match each. From what we can
see, controversies that follow each IPL match, have already begun. Viraat Kohli, the captain of
RCB, has been fined Rs. 12 lakh on Thursday for maintaining a slow over-rate against the King
XI Punjab. The minimum-over rate refers to the minimum number of overs to be completed within
an hour. 14.11 overs need to be completed in an hour in an IPL match that is not delayed. Else, it
becomes a breach of conduct.
Looking at the brighter side of things,
KL Rahul, the captain of Kings 11 Punjab, went on to score 132 runs and was adjudged to be the
Player of the Match. He also broke Sachin Tendulkar's record to become the fastest Indian bats-
man to reach 2,000 IPL runs. The KXIP skipper also registered the highest score by an Indian in
an IPL game, having smashed 14 boundaries and seven sixes.
